Description
The NVIDIA Mellanox MMA1B00-E100 is a pluggable QSFP28 optical transceiver for 100Gb/s InfiniBand links. It gives longer reach than passive copper cables and the flexibility of a separate optical cable, while keeping high port density. The electrical side presents a standard QSFP28 interface to the host system. The optical side uses an MPO connector with four optical lanes in each direction, each signaling at up to 25.78125GBd over multimode fiber.
The MMA1B00-E100 operates at an 850nm center wavelength and supports links of up to 70m on OM3 and 100m on OM4 multimode fiber. It complies with SFF-8665 and IEEE 802.3 100GBASE-SR4 and offers programmable Rx output amplitude, Rx output emphasis, Tx input equalization and selectable retiming. Digital diagnostic monitoring of optical power, bias current, supply voltage and case temperature is available through the I²C management interface. The module also works in NVIDIA end-to-end Ethernet applications.
