NVIDIA Mellanox® MMA1B00-C100D 100GbE QSFP28 SR4 Transceiver: This high-performance pluggable optical transceiver is engineered for 100 Gigabit Ethernet (100GbE) deployments. Utilizing a parallel 850nm VCSEL array, it delivers robust connectivity over multi-mode fiber (MMF). This is a pluggable transceiver module with an MPO/MTP interface, requiring a separate MPO-12 fiber patch cord for operation.
🔧 Technical Specifications
OEM: NVIDIA / Mellanox
P/N: MMA1B00-C100D
Form Factor: QSFP28
Interface: 100GBASE-SR4 (MPO-12/MTP-12 APC)
Data Rate: 100GbE (4x 25.78Gb/s)
Wavelength: 850nm
Reach: 70m (OM3) / 100m (OM4)
Power Consumption: < 3.5W (Typical 2.5W)
🌐 Engineering Context: The MMA1B00-C100D utilizes the CAUI-4 electrical interface to provide seamless interoperability with standard Ethernet switching silicon. Unlike AOCs, this transceiver allows for flexible structured cabling designs, enabling technicians to run MPO trunk cables through plenums and risers. It features selectable re-timing (CDR) for both transmit and receive directions, ensuring pristine signal recovery even in complex, multi-patch environments.
🧠 Typical Use Cases
100GbE Leaf-to-Spine uplinks using MPO structured cabling.
Enterprise data centers requiring modular fiber distances (up to 100m).
Connecting NVIDIA ConnectX-4/5/6 Ethernet adapters to Spectrum switches.
Breakout configurations (1x 100G to 4x 25G) using MPO-to-LC harness cables.
 
✅ Compatible With: NVIDIA Spectrum (SN2000/SN3000/SN4000 series) Ethernet Switches, ConnectX-4 Lx, ConnectX-5, and ConnectX-6 Ethernet Network Interface Cards (NICs). (Requires ports configured for native 100GbE SR4 operation)
❌ NOT Compatible With: InfiniBand EDR ports (Use MMA1B00-B100D for InfiniBand); LC-terminated fiber cables (Requires MPO); Single-mode fiber (SMF) infrastructure.
 
🛠️ Installation & Maintenance
Connector Hygiene: The MPO/MTP connector face contains 12 exposed fiber cores. It is critical to use a "One-Click" MPO cleaner before every insertion to prevent signal loss caused by microscopic dust.
Cabling: Requires 12-strand (or 8-strand utilized) MPO-12 Female (pinned-to-unpinned) cabling. Ensure polarity (Type B) matches your network design.
Forward Error Correction (FEC): For 100GbE operation, RS-FEC (Reed-Solomon) is typically required on the host port to ensure link stability at 100m distances.
