Introduction
The NVIDIA MMS4A00 is a 1600Gb/s 2xDR4, single mode optical transceiver supporting the XDR 800Gb/s InfiniBand protocol. The line rate is 200Gb/s using Pulse Amplitude Modulation at 4-channels denoted as 200G-PAM4 enabling two data bits to transfer per clock pulse.
The electrical configuration is 8-channels of 200G-PAM4. Optical configuration is based on two Datacenter Reach, 4-channel (2xDR4), 800Gb/s optical connectors.
Optical connectors are Multiple Push-On 12-fiber, Angled Polished Connector or MPO-12/APC. Two MPO-12/APC optical connectors are used per transceiver.
The 2x800G transceiver engine enables the InfiniBand Quantum-X800 QM3400, 72-cage switch to support 144-ports of 800Gb/s.
Based on 9-um, single mode fibers, the main application is linking two switches together up to 500-meters, or to two 800G links to two switches or network adapters for storage and compute servers. The 500-meter length assumes two optical patch panels or four optical connectors in the link.
NVIDIA’s transceivers guarantee optimal operation in NVIDIA end-to-end InfiniBand systems, and rigorous production testing ensures the lowest bit error rates, low-latency, and best out-of-the-box installation experience, performance, and durability.
