Vodafone and Alcatel-Lucent conduct Europe’s first TWDM-PON trial V odafone and Alcatel- Lucent are set to conduct Europe’s first field trial 10 Gigabit GPON (XG-PON1) and 10 Gigabit EPON. The Full Service Access Network (FSAN) Group and ITU are completing
of a time and wavelength- division multiplexed passive optical network (TWDM-PON), in investigations aimed at discovering the potential of using access network technology over Vodafone’s existing infrastructure. Vodafone said that the field trials build on the successful completion of their lab trial in Vigo, Spain, where Alcatel- Lucent’s TWDM-PON technology achieved bit rates of up to 20Gbps using two wavelengths. Gavin Young, Vodafone’s head of fixed access, said “We have been engaged with Alcatel- Lucent for several years on TWDM-PON development, testing and trial activities, and all of which have shown great results. We look forward to conducting field trials of TWDM- PON technology in Europe.” TWDM-PON is the next- generation access scheme after
the standard that supports up to eight wavelengths, each capable of 10 Gigabit symmetrical or 10/ 2.5 Gigabit asymmetrical speeds. The combination of time and wavelength division multiplexing allows TWDM-PON to support multiple PONs, each sharing its capacity among 16, 32, 64 or even 128 end points depending on the operator’s chosen split ratio. Operators can start with a 10 Gig PON using fixed-wavelength optics and move to TWDM- PON and tunable modules as their capacity needs grow. “You won’t have to swap out legacy XG-PON1 hardware two years from now,” said Stefaan Vanhastel, director of fixed access marketing at Alcatel- Lucent. In 2014, Alcatel-Lucent introduced a four-wavelength TWDM-PON based on a

operational efficiencies that keep them competitive in a challenging market. We are committed to providing them with innovative technologies that will allow them to reduce costs and deliver new services more easily. That is why TWDM-PON is such an important development for them.” First operator TWDM-PON pilot deployments will occur in 2016, says Alcatel-Lucent.
4-port line-card, each port supporting a 10 Gigabit PON. The line card is used within Alcatel-Lucent’s 7360 Intelligent Services Access Manager FX platform, and supports fixed and tunable SFP optical modules. Federico Guillén, president of Alcatel-Lucent’s fixed access business line, said “Vodafone wants to grow capacity to meet customer demand. They also want to benefit from
Witcom deploys Adva FSP 3000 system to enable ‘dynamic connectivity’ A dva Optical Networking has announced that German telecommunications carrier, customers want more bandwidth than ever before. Adva’s ROADM technology provides us with a dynamic infrastructure and enables us to move away from a provisioning new services and bandwidth. The network was

WiTCOM, has deployed the Adva FSP 3000 with reconfigurable optical add- drop multiplexer technology throughout the Hessen region of Germany. The carrier is utilizing the ROADM capabilities to transform its previously fixed network into what it calls “a flexible and dynamic infrastructure”. Rainer Naaß, manager, IT-Business and Planning, WiTCOM, commented, “We need a network that can grow at the same pace as our clients’ demands. Enterprises are calling for faster access to mission- critical data and residential
rigid and costly infrastructure.” WiTCOM operates a 500km network with eight nodes connected in a ring architecture. The newly installed ROADM system transforms the network into a meshed ring topology and links between all sites can be configured instantly through adding and dropping wavelengths on multiple fibres. The Adva FSP 3000 was selected for its ability to enhance the flexibility and scalability of its metro network. The new system enables WiTCOM to rapidly respond to the growing demands of customers by

partner, Dacoso, a specialist in connectivity solutions and data center services, in the company’s laboratories in Langen, Germany. Operators were also trained in how to utilize the embedded multi- layer GMPLS Control Plane, RAYcontrol. The combination of Adva’s hardware and software has, said WiTCOM, “resulted in true network automation, dynamic routing and self- learning. It dramatically simplifies operations, drives energy efficiency throughout the network and provides an abundance of new revenue opportunities.”
Martin Stengel, CTO at Dacoso, added, “Together with Adva, we have safeguarded the future connectivity of WiTCOM’s customers. Building on what was already a successful three-way partnership, we were able to remove the rigid nature of WiTCOM’s network and supply them with a versatile, efficient and scalable solution. This relationship is set to go further as WiTCOM is planning to enhance its network with Adva’s ConnectGuard encryption solution.”
