Cisco, Nvidia debut ultra-dense pluggable optics with 400 Gbps electrical lanes
Cisco and Nvidia have unveiled a new optical pluggable architecture designed to surpass the bandwidth of existing 1.6 Tbps modules by at least fourfold. The Ultra-Dense Small Form Factor Pluggable (USFP) technology will be used to develop 400 Gbps-per-electrical-lane modules in a reduced physical package. Nvidia said an initial line-up of USFP transceivers would supply sixteen full-duplex lanes in a similar physical footprint to the octal small form factor (OSFP) standard, enabling an aggregate capacity of
