As ECOC, the largest conference on optical communication in Europe and actually one of the largest such gatherings events in this field worldwide, rolls around to Gothenburg (and as CIOE 2017 addresses the latest developments in opto-electronics at the Shenzhen Convention & Exhibition Center in China), this issue of Optical Connections provides a handy companion piece to the events, with news and features on many of the hot topics under discussion. Hot topics this year include fibre devices and amplifiers, integrated devices and processors, digital techniques, subsystems and network elements, point- to-Point Transmission Links as well as core, metro and, of course, data centre networks. Gothenburg, in the heart of Scandinavia, is an apt location because Nordic countries have a great tradition of developing optical telecoms technologies – as Danish industry expert Per Danielsen reports on page 18. Hybrid optical and wireless networks oering flexible benefits are described by John Williamson, who says that hybrid networks in broadband access and distribution networks oer flexibility in network design; increased service variety and ultimately greater customer satisfaction. See page 22. With standards for 5G wireless networks still being finalised, there are many diverse options for fibre’s future role, says Andy Extance: optical technologies are supporting not only fronthaul and backhaul, but also crosshaul. Read all about it on page 24. Hardly a day passes without a media report of a network security problem – hacking, data leaks, shutdowns of company networks and so on. So how can better security be designed into optical networks? Ellen Manning investigates this hot topic on page 28. Software innovations in management are changing the nature of optical networks, as was discussed at the latest Next Generation Optical Networks conference in Cannes. Antony Savvas attended and reports for us on page 30. We also have a specially contributed article from Intel on the latest developments in silicon photonics to boost data centre interconnectivity; specialist Robert Blum reports on page 33. Another contribution from Chris Dunford of Exfo outlines best practice for testing scalable G.Fast deployments, on page 44. Enjoy the shows – and enjoy Optical Connections. We would love to hear your feedback on both.

Researchers aim at 100 Gbits/s- plus lasers
A project underway at The University of New Mexico (UNM) is aimed at demonstrating that semiconductor laser devices can send data at a bandwidth speed of over 100 Gbits/s, with potential applications that could result in ten times the speed of current fibre optic networks. The project addresses the
energy-ecient high- speed optical data egress (exit) from a cryogenic environment to room temperature for further processing. “Ultra-high-speed (>100 GHz) on-chip modulation of integrated lasers is an important ‘holy grail’ for the ever-increasing demand for ultrafast communication,” Osiński concludes.
Newsroom website, author Sharon Steely quotes Prof. Osiński: “Development of inexpensive ultrafast chips operating at speeds exceeding 100 Gbits/s will have a huge societal impact by increasing the transmission capacity of fibre-based networks.” Osiński’s project explores the use of semiconductor ring lasers to provide
need for faster data transfer by increasing the speed at which signals are first generated to send through a fibre optic network.For the past two and half years, work has centred on numerical simulations of proposed devices. The laboratory work will be performed at UNM’s Center for High Technology Materials (CHTM). In a posting on the UNM

and a 40GbE link using the NSD protocol serves as the backbone for each R&S SpycerBox Cell. A second 40GbE link from every R&S Spycerbox Cell combines two storage units into a SAMBA cluster and connects it to the central 40/10GbE switch. This provides the media links for the transcoder farm as well as the I/O connections for the overall system. Each R&S SpycerBox Cell uses an additional 10 GbE dual link, running NSD blocks via the central switch to the connected R&S Venice servers. Separating the systems into input and output clusters optimises the I/O performance for the massive data rates within each cluster. The solution fulfils all performance requirements within a single system of only four HUs.
In April of this year, Rohde & Schwarz introduced a new, intelligent storage and file management solution at the NAB trade show in Las Vegas and, together with its partner, system integrator Jordi AG, the company were awarded a project for Zürich-based customer, tpc. tpc already has two R&S Venice ingest and playout servers in house and the new storage and file management solution will be added to an existing network. The network only has a limited number of ports and there is limited space in the available racks, so Jordi AG came up with a solution to install two clusters, one for read and one for write, each with two R&S SpycerBox Cell units using SSDs in a RAID 6 configuration.

Broadband a utility as important as running water to UK homeowners
Access to ultrafast broadband is now almost as important to new home buyers as running water and electricity. So says Rob Perrins, Chief Executive of UK property developer the Berkeley Group. Perrins reckons owners expect broadband to be available from the day they move in, and believes the company would risk losing buyers if new properties didn’t oer high-speed connectivity. Berkeley is partnering with Openreach in a UK nationwide scheme to connect all sizeable new housing developments in the UK with ‘full-fibre’ FTTP technology. Launched in February last year, the scheme was initially free for developments of 250 homes or more, then in May 2016 Openreach reduced it to 100 homes, and from November it was reduced further to 30 homes. The IoT (Internet of Things) has become the leading technology for digital transformation and is the number one priority for 92 per cent of organisations, according to global research findings published today by Inmarsat, a provider of global mobile satellite communications. The Inmarsat Research Programme study focusing on the enterprise application of the IoT revealed that machine learning (38 per cent), robotics (35 per cent), and 3D printing (31 per cent) were also key requirements for eectively delivering digital transformation for business.

The provision of FTTP infrastructure for free to all new housing developments with 30 or more homes is dependent on developers registering their site with Openreach and working together early in the
So far, Openreach has worked with developers to provide ultrafast broadband to more than 586,000 premises across 2,400 developments registered with Openreach to benefit from a free FTTP infrastructure, with many more expected to join over the coming months. This year, Berkeley Group has adopted ‘full fibre’ across almost every development it is building and will provide the technology to all future homes. “For new home buyers, high speed broadband has almost become a given now – it is like the power steering on a car – no one asks whether the car they’re buying has it anymore,” remarked Perrins.

Improved service delivery capabilities (47 per cent), better health and safety across the organisation (46 per cent), and greater workforce productivity (45 per cent) were identified as the top three benefits to be gained from the deployment of IoT- based solutions.

IoT the ‘top priority’ in driving digital transformation
Paul Gudonis, President, Inmarsat Enterprise, commented, “This research confirms that IoT is the leading technology in digital transformation, taking a steady lead over other forms of innovation. IoT acts as the eyes and ears of organisations and its value comes from how the data it collects is used to improve eectiveness across an organisation. As such, it is unsurprising that so many organisations are deploying to imply that challenges are absent. The research points to clear concerns – namely, security, skills, and connectivity. The increasing interconnectivity of devices, teamed with a heightened cyber-security landscape and a short supply of relevant skills, brings an array of issues. To overcome these challenges, collaboration is key. IoT to propel their digital transformation initiatives. “However, this is not

Almost half (47 per cent) of respondents believe that their organisation will need to rethink their approach to data security and make heavy investments to meet IoT security requirements. Some 45 per cent cite lack of skills as a particular challenge for their organisation in deploying IoT, while 29 per cent agree with the statement that connectivity issues threaten to derail their IoT deployments before they have even begun.

The second is a high- performance CFP2-ACO that has a reach of up to 4,000km at 100 gigabits and 650km at 200 gigabits. Elenion also has a 25-gigabit optical engine that will soon be launched as a datacom product. At the OFC show held in March, Elenion demonstrated the optical engine directly mounted on a Cavium QLogic network interface card connecting a server to a high-capacity Cavium Xpliant Ethernet switch chip. The demo showed how 16 NICs could be connected to the switch chip for a total capacity of 400 gigabits. “No more direct-attached cables or active optical cables, literally fibre-to-the-server,” said CEO, Larry Schwerin. Marc Rouanne, president of Mobile Networks at Nokia said: “There should be no doubt about the huge potential of 5G. Through 5G FIRST, Nokia is evolving its 5G strategy to drive the industry rapidly towards the adoption of standards-based commercial applications – as early as 2019. GROWING DEMAND FOR 5G NEW RADIO Thirteen leading telecommunications innovators, including Fraunhofer Heinrich Hertz Institute HHI, have joined forces to advance the development of new radio technologies for 5G (5G New Radio – 5G NR) driven by growing interest in mobile 5G applications based on fully standardized technology. The European research project ONE5G (aware Optimizations and advancements for the Network Edge of 5G New Radio) focuses on boosting the capacity of mobile networks, improving their energy efficiency and enabling a variety of new vertical use cases in dense urban areas as well as in rural environments. Besides Fraunhofer HHI, the members of ONE5G are Orange, Telefónica, Huawei, Intel, Nokia, Samsung, B-COM, WINGS ICT Solutions, as well as the universities Aalborg University, Freie Universität Berlin, Universidad de Malaga and the research institute Centre National de la Recherche Scientifique. ONE5G has received funding from the European Commission under the EU’s “Horizon 2020” initiative to drive research that enables a swift move towards 5G NR and advance digitization.
Elenion Technologies is progressing its optical engine design for the data centre that will soon be a product. Elenion has been working with Ethernet switch chip maker, Cavium, and data centre player, Microsoft, as part of its datacom work. The silicon photonics private company had been active for two and a half years and shipping a product before it announced itself last December. Since then Elenion has been shipping its coherent transceiver PIC – an integrated modulator-receiver assembly – first to Coriant and now other companies. The PIC is part of two Coriant CFP2 Analogue Coherent Optics (CFP2- ACO) pluggable modules for its Groove G30 platform used for data centre interconnect. One is a short- Meeting growing customer interest in 5G, Nokia is broadening its focus into multiple areas of early 5G mobility use cases, including enhanced mobile broadband and ultra-reliable, ultra-low latency communications. Nokia says it will be pushing for accelerated 3GPP industry standardization while building on early customer experiences with its Nokia 5G FIRST end-to-end solution, launched in February 2017 With clear interest for 5G mobility applications already emerging from operators, notably in markets like the US, China, Japan and South Korea, Nokia plans to implement early 5G specifications, enhancing 5G FIRST with the 3GPP 5G Phase I protocol. This 5G NR (New Radio) air interface standard (see below), which is due at the beginning of 2018, is designed to support a wide variety of 5G devices and services. Nokia will continue to evolve and expand 5G FIRST as an end-to- end solution, designed to drive broader market adoption of 5G, via both mobility and fixed applications, as well as testing multiple 5G use cases. The company is building on extensive field experience already gained with Nokia 5G FIRST. These and many other of the key elements of 3GPP-based 5G implementation will enable Nokia to extend the scope of interoperability testing with a variety of devices. Nokia will also continue its application of leading-edge technologies, such as chipset and radio frequency innovations, in its end-to-end 5G strategy.
The industry knows what the next-generation 400-gigabit client-side interfaces will
look like but uncertainty remains
regarding what form factors to use. So says Simon Stanley, analyst-

at-large at Heavy Reading. Implementing the desired 400-gigabit module designs is also technically challenging, which could present a market opportunity for 200-gigabit modules should any slip occur at 400 gigabits. “There is significant investment going into the QSFP-DD and OSFP modules. Developers of semiconductors and modules are hedging their bets which means they have got to develop for the QSFP-DD, so that is where the bulk of the development work is going,” said Stanley. “But you can put the same electronics and optics in an OSFP.” The big challenge for 400 gigabits is getting 100-gigabit-per-wavelength components cost effectively. This requires optical components that will work at 50 gigabaud coupled with 4-level pulse-amplitude modulation (PAM-4) that encodes two bits per symbol. There is the IEEE 400Gbase-DR4 standard that supports four individual fibres each carrying a 100Gbit/s signal. Other coarse WDM four-wavelength standards under development include the -FR4. The challenge of implementing 100-gigabit-per-wavelength designs is what gives 200-gigabit modules an opportunity. Instead of 4x50 gigabaud and PAM-4 for 400 gigabits, a 200-gigabit module can use existing 25-gigabit optics and PAM-4. “You get the benefit of 25-gigabit components and a bit of a cost overhead for PAM-4,” said Stanley. “How big that [200-gigabit] opportunity is depends on how quickly people execute on 400-gigabit modules.” The first 200-gigabit modules using the QSFP56 form factor are sampling now. Meanwhile the first 400-gigabit QSFP-DD and OSFP client-side modules are expected in a year’s time with volumes starting at the end of 2018 and into 2019.

Over the past five years Intel has worked with software companies, contributed to open source communities, and released tools and libraries designed to help developers take advantage of the performance and security features of the Xeon platform. Spelman commented, “Our Cloud, fabric, network and the links swivel while the fibre slides under the microtabs, an arrangement that keeps the fibre from spilling out of the links. The fibre is then routed out of the tray and toward the side of the panel to help keep the cable out of the way of the sliding tray and avoid any fibre being pinched or broken. The chassis is designed to fit a variety of network environments, including enterprise, telecommunications and cable TV.

Target customers for the platform are cloud and communications service providers, enterprises, HPC and AI engineers. “Our early-ship customers are already seeing great results. For example, AT&T is already running production trac and has seen a major performance improvement using 25 percent fewer servers per cluster,” said Lisa Spelman, vice president and general manager of Intel Xeon products and marketing in the Data Centre Group. “Customers on the Google

Senko’s next generation connector
Connector optimises 400G data centre performance

Senko Advanced Components has introduced a next generation connector
Connector accentuates ease of fibre breakout. “Optical connectors with low insertion and return loss will be essential components in DCs as signalling speeds increase and the use of higher level modulation such as PAM4 becomes more widespread,” points out CS Connector’s Product Development Manager, Tiger Ninomiya. “Also, as many of the DCs are deploying Leaf Spine architectures, easily manageable breakout capabilities are becoming a critical requirement for many of our customers.” Working with industrial experts at various standards bodies and with Multi Source Agreement (MSA) groups, the CS Connector has been developed for dual CWDM4 QSFP-DD and OSFP modules, which require a four- fibre channel. The CS Connector
LC connectors. For the future, operating from its multiple country locations, Senko intends to continue with its strategy of developing products “with” its customers instead of “for” its customers. According to Dr. Bernard Lee, Senko’s Regional Technology Director, development of the CS Connector is not only focused on achieving better connector performance in terms of insertion loss and return loss, but also on improving user friendliness, without compromising reliability. Another priority will be to address smaller footprint connectors that will allow multiple connectors to fit within the constrained physical space of existing MSA mechanical form factors, but also enhance ease of breakout.
specifically designed for Data Centre (DC) 400G optimisation. To accommodate the “lightspeed” upgrades currently taking place in hyperscale DCs, the reduced size CS Connector is not only capable of delivering low insertion and high return loss comparable to existing LC connectors, but with significantly reduced footprint. These attributes allow the CS Connector to support the use of the more advanced modulation schemes such as PAM4 which is associated with the 100G and 400G speeds. Meantime, working with the newly agreed QSFP- DD and OSFP pluggable form factors, the new CS Anritsu has introduced the MP1900A signal quality analyser, a next- generation bit-error rate test (BERT) platform. The new instrument is the successor to the MP1800A and has the same footprint as its predecessor, but is slightly taller, making room for a 12.1-inch touch-screen display and more slots to add test features. There is also an intuitive GUI that can display block diagrams and four applications at the same time. Remote commands matching each GUI function can be displayed
ferrules contained in one housing, with
the ferrules pitched 3.8mm apart. This represents about a 35% reduction in size compared to regular LC duplex connectors. It also allows two CS Connectors to fit in the QSFP-DD/OSFP module footprint, something that LC connectors cannot accomplish. Unlike MPO types of module, each pair of TX/RX fits in one CS Connector. This arrangement facilitates easy break-out without the use of fan-out jumpers or break-out boxes. For patch panel applications, the CS Connector oers a density that is about 38%
Molex debuts 56 Gbps channel zSFP+ interconnect system
Anritsu announces MP1900A signal quality analyser supporting 400 GbE and PCIe Gen4/5
21G/32G MU195020A pulse pattern generator (PPG), the MU195040A error detector, and the MU195050A noise generator. The instrument is backwards compatible with the MU181000B synthesizer and MU18500B jitter modulation source. The built-in PPG has intrinsic jitter of typically 115fs rms, as well as typical response times, Tr/Tf, of 12ps. Total peak-to- peak jitter is typically 6ps maximum and typical input sensitivity of the internal error detector is 15mV.
Molex has expanded its zSFP+ interconnect system to support 56 Gbps PAM-4 channels and provide enhanced signal integrity in a stacked 2XN port configuration. The updated system has multiple features that allow for greater flexibility, with EMI ganged cages which are available in multiple port sizes from 2x1 through 2x12. Chris Hagerman, global product manager, commented “Molex provides a passively cooled solution by using an enhanced airflow cage design to maximize airflow through the cage and connector eectively lowering the temperatures by about 17 degrees Celsius. This yields optimal thermal management for next-
generation systems while eliminating the need for costly heat sinks or cooling modules.” Molex has also created a next-generation terminal and wafer on the stacked integrated connectors. The advanced terminal provides superior signal integrity for 56 Gbps PAM-4 applications and users are able to merge standard cables and modules with the increased data-rate accepted. “As more devices are connected to the internet and bandwidth demand continues to increase, being able to stay ahead of the curve on the backend becomes more challenging for data centres, networking OEMs and telecoms” Hagerman added.

Nordic optical telcos PUNCH ABOVE THEIRWEIGHT
Peter Laurin, Head of Business Area Managed Services, Ericsson, says, “We anticipate IoT devices will surpass mobile phones as the largest category of connected devices as early as 2018 and, according to Ericsson’s latest Mobility Report, there will be 18 billion connected IoT devices in 2022. This massive uptake requires a dierent approach to network planning, design, operations and capabilities than traditional mobile broadband networks.” READY FOR 5G Nokia is also ready to help operators to launch the new 5G mobile services. With Nokia’s 5G FIRST approach, operators can gain a first-to-market advantage by launching 5G use cases before the standards have been finalized. 5G FIRST builds on Nokia’s commercial 5G Nokia AirScale and AirFrame platforms to provide a versatile solution that spans the network. merger between the Swedish and Finnish telecommunications companies, Telia and Sonera. This merger followed shortly after Telia’s failed merger with Norwegian telecommunications company Telenor, now its chief competitor in the Nordic countries. Telia has for many years been challenged by the many municipal networks in Sweden oering higher bandwidth with a fibre connection. Today the privately owned Com Hem reaches 40 percent of the Swedish households. More than two million households connected via their landlords or via open LAN networks (often owned by the municipality) are able to subscribe to Com Hem digital services in broadband, digital TV and telephony. Over 40% of the digital TV customers subscribe to TiVo – the next generation TV-service. Com Hem has over 2 million homes connected to their network, meaning that about four out of ten households in FTTH PENETRATION Telia Company is the result of a 2002
As ECOC comes to Gothenburg, it is apt to review the remarkable success of this corner of Europe in this industry. Danish native Per Danielsen reports.
M ore than sixty years ago, in 1946, the three Scandinavian countries Sweden, Norway and Denmark founded Scandinavian Airlines System – now better known as SAS. It was formed as a partnership by the three national carriers to handle the intercontinental air trac of the three Scandinavian countries. Since the beginning, 50 % of SAS has been owned by private investors and the other half shared by the three national governments. A good question to ask here and now is why do the Nordic countries have such a great tradition in developing optical and countries have also maintained a long tradition of cooperation within mobile communications. For example, in 1982 the first-generation mobile network NMT (Nordic Mobile Telephone) was launched in the four Nordic countries, Sweden, Norway, Denmark and Finland. It was the first fully cellular phone system. NMT was specified by the Nordic telecommunications administrations and opened for service on 1 October 1981. The success of NMT was important to Nokia (then Mobira) and Ericsson. First Danish implementers were Storno (then owned by General Electric, later taken over by Motorola) and AP (later taken over by Philips). NMT was gradually replaced by 2G (aka GSM) and was finally closed down in mobile communication systems? In a similar way to its approach to the airline business, the Nordic
2007. But a strong base for development of mobile communication had been established. However, in the telecommunications business the situation is quite the opposite, with the three incumbent carriers, TeliaSonera (based in Sweden), Telenor (Norway) and TDC (Denmark), actively fighting and competing in their respective neighbouring markets. INNOVATION TRADITION The Nordic countries have a long tradition of driving the development of telecoms, and the wider market is now seeing more and more Nordic companies taking steps towards developing and actively commercialising Internet of Things (IoT) products and services. The next generation of wireless mobile technology, 5G, is designed for IoT with requirements for low device power consumption, low latency and more capacity. Sweden and Norway are also among the European countries with the highest penetration of fibre-to-the-home. Ericsson, for example, has a long tradition in being a first-mover in mobile network technologies. As the first commercial Internet of Things (IoT) networks are introduced, Ericsson is complementing its cellular IoT software and IoT Accelerator oerings with a complete set of network services. These services enable service providers to eciently address the deployment and operation of the massive number of IoT devices being introduced to LTE networks.

data centre provider with a capacity of 13,000 m2 of secure co-location space. In June 2017, GlobalConnect announced that it intended to acquire Nianet, which is owned by 13 energy companies. GREEN ENERGY ATTRACTS DATA CENTRES The reason why the FTTH penetration in Denmark is so low (18.4 %) compared to the rest of the Nordic countries is that TDC is so dominant in the metro area around Copenhagen, the capital city. After TDC acquired two fibre networks from DONG Energy and ComX, it stopped rolling fibres out to private households. Instead TDC delivers broadband by its coax- and copper-networks. Outside of the capital region, the utility companies are owned by consumer groups and they have decided to roll out their own fibre networks. But in one notable field Denmark is in front, which is sustainable energy – this form of energy accounted for more than 30 percent of Danish energy consumption in 2015. Other Danish advantages are its low latency to Central European destinations and its direct subsea cables to the USA. Apple is planning to build two new data centres in the Danish towns of Åbenrå and Viborg on the Jutland Peninsula, both running on 100 % sustainable energy. These will power Apple’s online services, including the Apps Store, iTunes Store, iMessage, Maps and Siri, for customers across Europe. Google has also announced a new data centre at Fredericia, covering 117,740 square meters. And Facebook is to build another data centre in Odense of 184,000 square meters. Facebook’s investment in Odense is thought to be significant. In the town of Luleå in northern Sweden, Google opened a similar data centre in 2013, for which the investment was approximately SEK 3.8 billion (€400 million). But, then again, when you punch above your weight, the rewards are going to be a lot bigger than everybody would usually expect.
inclusive and sharing centre where members of academia, businesses, startup communities, organisations and authorities can contribute to and benefit from the development of new knowledge. The lab will be based on established principles for research ethics, to which contributors must adhere. DENMARK’S MOBILE QUARTET In Denmark the dominant player in the telecoms market is the incumbent operator TDC, which is the major player on fixed networks, cable TV and mobile networks. Telenor and Telia are also established in Denmark, where they oer both fixed line communication via TDCs copper network and their own mobile networks. All three companies are challenged on the mobile market by 3, which is a joint venture owned by Hong Kong-based CK Hutchison Holdings (60%) and Swedish Investor AB (40%). CK Hutchison Holdings works with telecoms in 11 countries across Europe, Asia and Australia. 3 in Denmark is so far only oering 3G and 4G mobile communications on its own mobile network and does not oer any fixed- network connections. In order to lower the cost, Telenor and Telia decided to build a new shared 4G network instead of upgrading their two existing separate networks. Later they also upgraded their common TT-network with 3G. After that Telenor and Telia, being second and third on the Danish mobile market, planned to merge their operations in Denmark into one company. The plan was however blocked by the EU Commission in 2015, which required them to first sell their low cost carrier Bibob and allow a new player to acquire up to 40 percent of their common mobile network. GlobalConnect is Denmark’s leading alternative provider of B2B data communication services, owning and operating 13.000 km of fibre. The company’s fibre infrastructure passes more than 30,000 companies in Denmark and 9,000 companies in Germany. GlobalConnect is also the largest Danish
Sweden, including the large metropolitan areas, can subscribe to broadband TV and telephony services from Com Hem. The fibre expansion has put pressure on the pay TV operator Boxer in the digital terrestrial TV-market. Boxer has approximately half a million subscribers predominantly is areas already reached by cable. So in 2016 Com Hem acquired Boxer to accelerate its reach in the single dwelling unit market. The high penetration of optical fibres in the ground has put Sweden at the top of the FTTH-penetration in Europe with a penetration of 41%. Only Latvia has a higher penetration – of 45%. Norway is second in the Nordic region with at penetration of 31%, followed by Finland (24%) and Denmark (18%). Another important player in Sweden, is Tele2, a European telecommunications operator with its headquarters in the Kista Science City, near Stockholm. It is a major telephone operator in the Nordic and Baltic countries and an alternative provider in many others, with about 14 million customers in 9 countries. POWERHOUSE FOR AI Norway’s Telenor is one of the world’s largest mobile telecommunications companies with operations in four geographic clusters: Scandinavia, Central and Eastern Europe, emerging Asia and mature Asia. It has extensive broadband and TV distribution operations in four Nordic countries. Telenor now owns networks in 13 countries. Telenor’s ambition is to leverage its scale, both through global operations and synergies within its four geographic clusters. In Norway and Sweden, Telenor plans to step-up its fibre roll-out, aiming to strengthen its market position within high-speed broadband. In addition, Telenor will explore early positions on fibre in emerging Asia, utilising the company’s existing mobile infrastructure. Telenor is very active within artificial single most important technology of our century. In the future, AI will drive your car, revolutionise cancer treatment and make public services more ecient. With this opening we want to accelerate the education, research and competency building which will be crucial for Norway’s ability to compete in the digital future,” says Sigve Brekke, President & CEO of Telenor Group. The new centre is financed by Telenor with NOK 50 million (€5 million) and the company’s researchers will participate in joint projects at the lab. NTNU (Norwegian University of Science and Technology) contributes with academic resources, infrastructure and technical assistance while the research organisation SINTEF will contribute with bringing the knowledge into practical use. Telenor-NTNU AI-Lab will be an intelligence (AI) and has recently established a new centre for AI in Trondheim, northern Norway. “Artificial intelligence is perhaps the
