NVIDIA Mellanox MCP1600-E002 QSFP28 EDR 100Gb/s Passive Copper Cable, 2m LSZH — Lot of 5: This is a lot of five 2-meter passive copper direct-attach cables (DAC) with QSFP28 connectors on both ends, rated for EDR InfiniBand at 100Gb/s. The cable uses a 28AWG conductor and a Low Smoke Zero Halogen (LSZH) jacket for data centers with strict fire-safety codes. This is a fixed-length passive copper assembly. Each unit is a refurbished cable.
Engineering Context
The MCP1600-E002 is engineered for short-reach EDR InfiniBand at 100Gb/s (4×25Gb/s NRZ). At 2m, it sits at the typical in-rack ToR-to-server reach. The 28AWG conductor balances signal integrity at 25G NRZ against bend flexibility. The LSZH jacket emits minimal smoke and no halogenated gases under thermal stress, satisfying mandatory plenum and modern data-center fire codes. Passive DACs consume 0 W and add no retiming latency on the link.
Deployment & Use Cases
EDR InfiniBand HPC clusters at 100Gb/s with ConnectX-4 / ConnectX-5 hosts. Top-of-Rack to compute-node links inside SB7700 / SB7790 / SB7800 switch fabrics. Storage backplane interconnects at 100Gb/s. Data centers with LSZH cable mandates where AOCs are not required at the 2m reach.

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. Not certified for 100GbE Ethernet operation; for 100GbE use the MCP1600-C series. Not a breakout cable: does not split into 4×SFP28 25G. Fixed 2m length; not field-shortenable.
