Brand: NVIDIA · SKU: MMA4Z00-NS400 · MPN: MMA4Z00-NS400 · Category: Networking
The NVIDIA MMA4Z00-NS400 is an InfiniBand (IB) and Ethernet (ETH) 400Gb/s, Single-port, OSFP, SR4 multimode parallel transceiver using a single, 4-channel MPO-12/APC optical connector. The Short Reach 4-channel (SR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using OM4 multimode fiber and assumes two optical patch panels in the link. It has identical design and internals as the QSFP112 version, only with different connector shells (Flat Top). The transceiver firmware supports both InfiniBand and Ethernet and is automatically enabled depending on the protocol of the switch attached to. It is typically used in ConnectX-7/OSFP-based network cards and linked to Quantum-2 InfiniBand or Spectrum-4 Ethernet switches. The transceiver features Digital Diagnostic Monitoring (DDM) for monitoring supply voltage, temperature, and optical power levels.
