Cisco pushes silicon photonics for enterprise, webscale networking

February 08, 2019 / Michael Cooney

Cisco says it's closed its deal to buy optical-semiconductor firm Luxtera for $660 million bringing it the advanced optical technology customers will need for speed and throughput for future data-center and webscale networks. When Cisco announced the deal in December, Rob Salvagno, Cisco vice president of Corporate Business Development, said, “As system port capacity increases from 100GbE to 400GbE and beyond, optics plays an increasingly important role in addressing network infrastructure constraints, particularly density and power requirements.” The combination of Cisco’s and Luxtera’s capabilities in 100GbE/400GbE optics, silicon and process technology will enable customers to build future-proof networks optimized for performance, reliability and cost, Salvago stated. The reason Cisco snatched-up Luxtera is its silicon photonics technology that moves data among computer chips optically, which is far quicker than today's electrical transfer, Cisco says...
