NVIDIA Mellanox MCP1600-C01C 1m QSFP28 100GbE Passive Copper Cable: This is a 1-meter passive copper QSFP28-to-QSFP28 Direct Attach Cable rated for 100Gb/s Ethernet. The MCP1600 'C' suffix family is the Ethernet variant of the line. It is a fixed-length factory-terminated assembly, not a transceiver-with-MPO-patch. This is a new unit.
Engineering Context
The MCP1600-C01C carries 4 lanes of 25Gb/s NRZ over high-bandwidth twinax copper to deliver 100Gb/s aggregate. At 1m, the cable typically uses 30AWG conductors for tight bend radius and rack-internal cabling without restricting airflow. Passive design means zero power draw on the host port and sub-5ns per meter propagation latency. Full EMI shielding via twinax construction. No optics to fail and no transceiver firmware involved. BER conforms to IEEE 802.3bj specifications for 100GBASE-CR4 with RS-FEC where required by the host.
Deployment & Use Cases
ConnectX-4 / ConnectX-5 / ConnectX-6 Dx EN adapter to NVIDIA Spectrum (SN2000, SN3000, SN4000) Top-of-Rack switch within a single rack. Storage fabric uplinks on 100GbE NVMe-oF arrays. Hyperconverged compute node interconnect inside a 1U-2U gap. Lab and bench setups for adapter qualification and short-reach 100GbE link validation.
Technical Specifications

Cable Type: Passive Copper Direct Attach (DAC)
Length: 1 meter
Protocol: 100GbE Ethernet (Mellanox 'C' variant)
Power Draw: 0W (passive)

Compatibility & Hard Constraints
Compatible with NVIDIA Spectrum (SN2000 / SN3000 / SN4000) switches and ConnectX-4 / -5 / -6 Dx EN adapters operating at 100GbE. Compatible with QSFP28 ports rated for 25Gb/s per lane NRZ. Not compatible with EDR / HDR InfiniBand ports unless the switch firmware permits 100Gb-Eth on those ports (the 'C' suffix is the Ethernet variant). Not a breakout cable — direct 1:1 only, not QSFP28-to-4xSFP28. Fixed 1m length — no field-length adjustment. RS-FEC enablement on the host port may be required depending on switch firmware.
