Cisco updates Silicon One family of network chips with speedy new switching device SHARE Cisco Systems Inc. today is updating its family of Silicon One semiconductors used in next-generation 5G network switches and routers. The new processors include a high-end chip designed to enable “web-scale” switching at unprecedented speeds, boasting an industry-first maximum bandwidth of 25.6 terabytes per second. Cisco debuted its Silicon One chip architecture back in December 2019, saying at the time it was aiming to create a “common foundation for tomorrow’s networks.” The Silicon One processors are used to build both modular and fixed routers and switches in large networks operated by major enterprises and telecommunications firms.
