Description

The growing use of the Internet has created increasingly higher demand for multi-Gb/s I/O performance. The demand for 1 Tb/s+ WAN bandwidth fuels the growth of short-reach 120 Gb/s infrastructures within high-end telco and datacom routers, switches, servers and other proprietary chassis-to-chassis links.
