NVIDIA and Cisco (Cisco) announced yesterday local time that they have jointly launched the industry's first pluggable optical module specification that supports 400Gbps/ lane high-speed signals.
The USFP and OSFP optical modules are of similar size. The first batch of products integrates 16 full-duplex channels, which can be expanded to 32 or even more channels in the future, thereby achieving a throughput of 12.8 Tb /s.
The bandwidth of the optical module can reach 4 times that of the current 200G lane; and with the support of 400G SerDes technology, the energy efficiency of USFP is 1.3 times that of the latter.
It adopts a new type of two-dimensional array connector, which features a two-step insertion design that allows for the connection of high-speed contacts only after the module is inserted. This reduces contact wear, improves signal integrity, and makes the insertion force more predictable; it supports a power consumption of 100W, simplifying the design of switches.
