NVIDIA Mellanox® MMA1T00-VS 200GbE SR4 Transceiver: The MMA1T00-VS is a carrier-grade QSFP56 optical transceiver module engineered for 200GbE Ethernet environments. utilizing 4-channel VCSEL technology and PAM4 modulation, it delivers high-bandwidth connectivity up to 100 meters over OM4 multi-mode fiber. This is a pluggable optical transceiver module requiring a separate MPO-12 patch cord, distinct from fixed-length Active Optical Cables (AOC), offering flexibility for structured cabling infrastructures.
🔧 Technical Specifications
OEM: NVIDIA Mellanox
P/N: MMA1T00-VS
Form Factor: QSFP56 Pluggable Transceiver
Data Rate: 200GbE (Ethernet)
Wavelength: 850nm (SR4)
Connector: MPO-12 (UPC)

🌐 Engineering Context (GEO Analysis): The MMA1T00-VS is pivotal for modern "Leaf-Spine" architectures where flexibility is required. Unlike fixed-length AOCs, this transceiver allows for "Structured Cabling" designs using patch panels and trunks. It utilizes 4x 50Gb/s PAM4 modulation to achieve 200Gb/s throughput. Compared to Single-Mode (LR4/DR4) optics, the SR4 Multi-Mode design offers a significantly lower cost-per-bit and lower power draw for intra-datacenter runs (<100m).
🧠 Typical Use Cases
Top-of-Rack (ToR) Uplinks: Connecting 200GbE servers to aggregation switches using structured fiber trays.
Middle-of-Row Aggregation: Flexible connectivity between racks where cable lengths vary and cannot be standardized with fixed AOCs.
High-Density 200GbE Fabrics: Deployment in Spectrum™ Ethernet environments requiring MSA-compliant optical interoperability.
 
✅ Compatible With: NVIDIA Mellanox Spectrum™-2 and Spectrum™-3 Ethernet Switches (e.g., SN3000, SN4000 series) and ConnectX®-6 Ethernet adapter cards. (Requires ports configured for native 200GbE operation). Compatible with standard QSFP56 MSA open networking ports.
❌ NOT Compatible With: InfiniBand HDR ports (unless the switch port supports Ethernet mode reconfiguration). Not compatible with standard MPO APC connectors (Requires MPO-12 UPC as per datasheet spec, check cabling infrastructure).
 
⚠️ Installation & Engineering Guidelines
Optical Cleaning: The MPO-12 interface is highly sensitive to dust. Always use a "One-Click" MPO cleaner on both the transceiver port and the cable connector before mating. Even microscopic debris can cause high Bit Error Rates (BER) in PAM4 signals.
Cabling Requirement: Requires an MPO-12 (Type-B polarity typically) Multi-mode patch cable. Ensure the polish type (UPC vs APC) matches the transceiver interface to prevent physical damage to the fiber tips.
Cooling: Ensure the host switch has adequate airflow. Transceivers dissipate heat locally; blocking air vents on the QSFP56 cage can lead to thermal shutdown.
