Sumitomo has been awarded a contract for the Stikine Crossing Submarine Cable Replacement Project from Southeast Alaska Power Agency (SEAPA). The project involves replacing a 138kV OF (Oil Filled) submarine power cable with an environmentally friendly 69kV XLPE (Cross-linked polyethylene) submarine cable with ancillary equipment for a fully functional system in the Stikine crossing (approx. 16,700 feet) between Vank and Woronkofski Islands, near Wrangell, Alaska, USA.
The 400GE BiDi MSA Group founded in July focuses on promoting interoperable 400GE optical specifications that utilize multi-mode fiber (MMF) for applications up to 100m link distances. The MSA leverages BiDi technology that has been widely deployed by Cisco and others for 40GE and 100GE applications over duplex MMF. With the arrival of 400GE applications, customers will finally have no choice but to start using MMF transceivers that require more than duplex fiber. 400GE ports can be used to aggregate traffic from 100GE ports, still leveraging the duplex MMF from 100GE BiDi modules to 400GE modules in a breakout configuration as shown in the diagram below.
Sumitomo Electric Lightwave has released the newest addition to the Quantum Fusion Splicer portfolio, Type-Q102-M12. The splicer’s new features and benefits, including consistent, quality low-loss splicing, compatibility with Lynx Custom=fit 2 splice-on connectors, and SEL’s dual independent ovens, make the splicer capable of deploying next-generation hyperscale networks.
Optoscribe and Sumitomo Electric Industries have partnered with the University of L’Aquila, Italy, to establish the first multi-core fiber (MCF) testbed for space-division multiplexed (SDM) communications in a real-world field environment. The collaborators expect the MCF testbed will host R&D activities related to SDM transmission over MCFs for optical communications. The testbed will see use for device testing, transmission experiments, and software-defined networking research. It also will be part of an ongoing 5G trial; L’Aquila is one of five Italian sites selected for trialing 5G technologies.
