NVIDIA Mellanox MCP1600-E00A QSFP28 EDR 100Gb/s Passive Copper Cable, 0.5m — Lot of 5: This is a lot of five 0.5-meter passive copper direct-attach cables (DAC) with QSFP28 connectors on both ends, rated for EDR InfiniBand at 100Gb/s. This is a fixed-length passive copper assembly with a 30AWG conductor and black PVC jacket. Each unit is a refurbished cable.
Engineering Context
The MCP1600-E00A is engineered for ultra-short-reach EDR InfiniBand connections at 100Gb/s (4×25Gb/s NRZ). At 0.5m, it is the shortest length in the MCP1600-E series and is used for in-rack adjacent-port links such as switch-to-switch stacking or NIC-to-NIC clustering. The 30AWG conductor and PVC jacket keep the cable lightweight and flexible, optimised for tight bend radii in dense rack layouts. Passive DACs draw 0 W and add no retiming latency.
Deployment & Use Cases
EDR InfiniBand HPC clusters where adjacent ConnectX-4 / ConnectX-5 nodes must be linked at 100Gb/s with minimal cable length. Spine-leaf stacking on adjacent SB7700 / SB7800 switch ports. Storage backplane interconnects at 100Gb/s. Compact 0.5m runs where AOCs are unnecessary and copper is preferred for cost and zero-power operation.

Compatibility & Constraints
Compatible with NVIDIA Mellanox EDR InfiniBand QSFP28 ports on ConnectX-4 / ConnectX-5 / ConnectX-6 VPI adapters and SB7700, SB7790, SB7800 EDR switches. The MCP1600-E series is the EDR (100Gb/s) family — for HDR (200Gb/s) use the MCP1650 series instead. Not certified for 100GbE Ethernet operation in published documentation; for 100GbE use the MCP1600-C series. Black PVC jacket — does not meet LSZH plenum requirements; for LSZH use the matching -L variant. Not a breakout cable.
