NVIDIA Mellanox MCP1600-E001 QSFP28 EDR Passive Copper Cable, 1m: This is a 1-meter passive copper QSFP28-to-QSFP28 cable for InfiniBand EDR (100 Gb/s) point-to-point links. The cable is a fixed-length integrated assembly with 30AWG copper conductors and an LSZH jacket; it is not a transceiver pair with a removable patch cord. NVIDIA P/N 980-9I62P-00C001. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MCP1600-E001 carries 4 lanes of 25 Gb/s NRZ signaling for an aggregate 100 Gb/s, the EDR rate. At 1 m the link sits well inside the passive copper budget for EDR, so no active equalization or retimer is required. 30AWG conductors keep the cable thin and flexible enough for in-rack fanouts where bend radius matters. The LSZH jacket meets data center fire safety codes that prohibit halogenated jackets. The cable's EEPROM is Mellanox-coded so ConnectX-4/-5 adapters and Switch-IB 2 series switches autoconfigure the link.
Deployment & Use Cases
Top-of-Rack switch to ConnectX-4 / ConnectX-5 HCA in HPC and AI training clusters. NVMe-oF storage targets where a 100 Gb/s RDMA fabric is required at short reach. GPU-to-GPU and GPU-to-storage connections inside DGX-class chassis where 1 m is sufficient. Lab and bring-up of EDR fabrics where a short, known-good cable accelerates fault isolation.

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox Switch-IB 2 (SB7700/SB7800) EDR switches and ConnectX-4 / ConnectX-5 VPI HCAs in InfiniBand mode. Operates as 100 GbE on Spectrum SN2000-series switches when ports are configured for Ethernet. Fixed 1 m length — the assembly cannot be shortened or extended. Passive only — contains no retimer or active conditioning. Not compatible with FDR-only (56 Gb/s) ports for full-rate EDR operation. Not compatible with QSFP+ ports requiring 14 Gb/s-per-lane FDR signaling without rate negotiation. Not a breakout cable.
