NVIDIA Mellanox MFS1200-E005 InfiniBand EDR QSFP28 Active Optical Cable, 5m: This is a 5-meter active optical cable (AOC) engineered for InfiniBand EDR (Enhanced Data Rate) at 100Gb/s. The cable uses VCSEL optics over multi-mode fiber to provide a fixed-length integrated assembly. This is a QSFP28 to QSFP28 point-to-point cable, not a transceiver pair with a separate fiber patch cord. This is a new unit.
Engineering Context
The MFS1200-E005 supports EDR InfiniBand at 100Gb/s using 4 lanes of 25Gb/s NRZ encoding. AOCs at 5m are commonly used for in-rack and adjacent-rack connections where passive copper cable bulk becomes problematic. The active optical design provides full EMI immunity and a much smaller bend radius than copper. Power consumption is approximately 3.5W per cable end. BER is rated at less than 1E-15.
Deployment & Use Cases
HPC compute fabric interconnects between server racks. GPU-to-GPU communication for distributed deep learning training (NCCL, MPI). Spine-leaf InfiniBand topologies in storage clusters. Connecting compute nodes to NVMe-oF storage targets over EDR fabrics.

Cable Type: Active Optical Cable (AOC)
Length: 5m
Protocol: InfiniBand EDR
BER: <1E-15
Per-End Power: ~3.5W
Condition: New — Factory sealed, supplied by T.E.S IT-SOLUTIONS
Compatibility & Constraints
Compatible with NVIDIA Mellanox EDR InfiniBand switches in the SB7000 family (e.g., SB7700, SB7790, SB7800) and ConnectX-4 / ConnectX-5 VPI adapters in InfiniBand mode. Requires ports configured for InfiniBand EDR. This is a fixed 5m assembly with no breakout support. Not interchangeable with the MFA1A00 series, which is built for 100GbE Ethernet rather than InfiniBand EDR. Not compatible with ports limited to FDR or QDR rates without rate negotiation.
