NVIDIA® MMA1B00-C100D is a 4-channel, pluggable QSFP28 optical transceiver designed for use in 100GbE Ethernet links with up to 100 m reach on multi-mode fiber (MMF). This transceiver incorporates our integrated circuit technology to provide high performance at low power.

The MMA1B00-C100D converts 4 input channels of 25 Gb/s electrical data to 4 optical signals at 850 nm. Reversely, the receiver side de-multiplexes 4 optical inputs into 4 electrical differential output signals.The transceiver has selectable retiming as specified in the SFF-8636 MSA. The transceiver can therefore be used in both 40 GbE and 100 GbE applications.

Digital diagnostic monitoring functions for temperature, supply voltage, and optical power are available via the two-wire (I2C) management interface, as specified by the QSFP28 MSA.

The optical interface is a Multi-fiber Push-On (MPO) connector with four optical channels/fibers in each direction. The MPO connector is un-angled (UPC).

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