NVIDIA Mellanox MMA1T00-VS 200GbE QSFP56 SR4 Multi-Mode Optical Transceiver: This is a pluggable QSFP56 optical transceiver module engineered for 200Gb/s Ethernet (200GbE) over multi-mode fiber. The module uses 4-channel VCSEL optics with PAM4 modulation and an MPO-12 interface. This is a separate transceiver that requires an external MPO-12 patch cord; it is NOT a fixed-length AOC cable assembly. This is a refurbished unit.
Engineering Context
The MMA1T00-VS implements 4 lanes at 50Gb/s PAM4 to deliver an aggregate of 200Gb/s in QSFP56 form factor. It transmits at 850nm over OM3/OM4 multi-mode fiber. SR4 multi-mode optics offer significantly lower cost-per-bit and lower power draw than single-mode LR4/DR4 alternatives for intra-data-center reach. The module supports MSA-compliant interoperability with QSFP56 host ports.
Deployment & Use Cases
Top-of-Rack to aggregation uplinks at 200GbE in structured cabling deployments where flexible patch lengths are required. Middle-of-row connectivity between racks where fixed AOC lengths cannot be standardized. 200GbE leaf-spine Ethernet fabrics built around Spectrum-2 or Spectrum-3 switches and ConnectX-6 adapters.

Compatibility & Constraints
Compatible with NVIDIA Spectrum-2 and Spectrum-3 Ethernet switches (e.g., SN3000 and SN4000 series) and ConnectX-6 Dx Ethernet adapters configured for 200GbE. Requires a separate MPO-12 multi-mode patch cord (OM3 or OM4); cord and polarity must match the link partner. NOT compatible with InfiniBand HDR ports unless the host port is reconfigured to Ethernet mode where supported. Not for use with single-mode fiber or APC connectors. Not an AOC, no fixed cable attached.
