Southern Cross Achieves 800G with Ciena’s WaveLogic 5
CST Global develops un- hackable Quantum Key Distribution technology
Responding to ongoing demands for bandwidth, Southern Cross Cable Limited has connected the first single-wavelength 800G across a live production network using Ciena’s WaveLogic 5 Extreme (WL5e) coherent optics. The new 800G channel speed ran error- free on Southern Cross’ live production network between two large, global data centres on the U.S. West Coast and demonstrated record- breaking spectral efficiencies. Southern Cross will begin volume deployment of WL5e in the second quarter of 2020 across various segments of its network, including Trans-Pacific submarine cables and terrestrial cables across U.S. West Coast and New Zealand. Southern Cross currently owns and operates a Trans- Pacific submarine cable network connecting Australia, New Zealand, Fiji and Hawaii The Fraunhofer Heinrich Hertz Institute HHI, has developed a USB-powered LiFi system with low power consumption with a data rate of up to 1 Gbps in a mobile LiFi terminal. Fraunhofer HHI develops LiFi systems with a focus on applications in target environments such as backhaul, industry and for conference and classrooms. Overall, the institute has more than 20 years of experience in the field of LiFi and offers the
to the mainland United States. The network has 28,900 kilometres of submarine cables and 1,600 kilometres of terrestrial fibre optic cables. It is currently implementing a third high-capacity route to its ecosystem, the Southern Cross NEXT project, which is due for completion by the end of 2021 with a planned capability of 72Tbps+. Southern Cross is using Ciena’s GeoMesh Extreme solution, which includes the 6500 Packet-Optical Platform powered by WL5e, to upgrade capacity by more than 40 times the original design potential, utilising the same infrastructure that was originally designed to transport 2.5Gbps wavelengths. Rick Seeto, Vice President and General Manager of Asia-Pacific and Japan, Ciena commented, “With WaveLogic 5, we are delivering the industry’s first 800G solution and reinforcing our leadership in providing the highest performance optics in the market.” compact USB LiFi modules for pilot installations, field tests and licenses also for industrial product development. LiFi enables fast mobile communication indoors. With a LiFi transmission, the unlicensed optical spectrum is used for wireless data transmission. In contrast to radio, light can be limited to certain rooms in a controlled manner, thereby protecting the data from unauthorised access and external interference with very high
Scotland-based CST Global has developed Quantum Key Distribution (QKD) emitter and detector technologies as part of a UK-funded, government project. The company says these technologies can enable totally secure, network communications. QKD suits mission-critical, client server applications, where unbreakable security codes prevent hacking and malicious attack. QKD can be applied to existing IT infrastructures and offers a high-security, data transmission option within the rapidly expanding, optical communications market. QKD has been developed as part of CST Global’s core competence in Quantum technologies. QKD is a result of CST Global’s involvement in the QR-SPLED, government- funded project and the ‘Single Photon Infrared Detectors for Quantum Systems’ project with Amythest research and Lancaster University. QKD requires a single-
photon, Quantum Light Source (QLS) to transmit data and a Single-Photon Detector (SPD) to receive it. CST Global has both QLS and SPD technologies developed to microscale, through government-funded projects. The SPD receiver also operates at room temperature, instead of at the impractical, cryogenic temperatures of previous solutions. CST Global’s QKD solution operates at room temperature deployment in pc, server or smartphone applications. The company is actively seeking a commercial partner interested in developing a dedicated, nanoscale chip for widespread use. CST Global provides both a custom foundry service, as well as a range of high-volume, standard laser products for the optical communications markets. It is an active partner in the UK and European, Technology Consortium Programme. and is potentially small enough, cheap enough and practical enough for

possible data rate should be achieved, says HHI. With an average consumption of only 3 watts, a scenario has now been demonstrated in which a ceiling lamp provides several users on their notebooks with fast network access. Peak data rates of up to 1 Gbps were achieved. The user thus receives an extremely powerful LiFi module with a small form factor.
A constant development goal is to develop a device that is as compact as possible for mobile use on a notebook. In the third generation, the Fraunhofer HHI development team headed by Jonas Hilt and Peter Hellwig have now succeeded in presenting a particularly light and compact module. The big challenge during the development was the low performance that can be obtained from a USB interface on a mobile
