12.8 Tb/s Capacity in OSFP Form Factor

The first transceivers planned based on USFP will combine 16 full-duplex lanes in a module the size of an OSFP (octal small form factor). They are intended for both switches and SuperNICs, with the possibility of scaling to 32 lanes and beyond in the future. According to the statement, customers will be able to achieve overall capacity of 12.8 Tb/s.

By doubling both the number of lanes and bandwidth per lane, the format should enable connection of more terminals at 1.6 Tb/s without adding network layers. Compared to pluggable modules at 200 Gb/s per lane, Nvidia and Cisco claim bandwidth and front-panel bandwidth density multiplied by 4, as well as energy efficiency approximately 1.3 times higher.

The economic mechanism described by both groups is as follows: when a switch reaches its capacity, network expansion may require additional switching layers and optical links, which increases latency, power consumption and costs. USFP aims to…
