The NVIDIA MMS1V00-WM transceiver is a single-mode 4-channel (DR4) QSFP-DD optical transceiver, designed for 400 Gigabit Ethernet (GbE) links on up to 500m of single mode fiber.

The MMS1V00-WM converts 8 input channels of 50Gb/s PAM4 electrical data to 4 channels of 100Gb/s PAM4 optical signals, using a nominal wavelength of 1310nm, for 400Gb/s optical transmission.

The transceiver has a standard QSFP-DD connector on the electrical side towards the host system. The optical interface is composed of four optical channels/fibers in each direction, intended for a parallel single-mode optical cable via a standard MPO connector.

Rigorous production testing ensures the best out-of-the-box installation experience, performance, and durability.
