NVIDIA Mellanox MCP1600-C002 100GbE QSFP28 Passive Copper Direct Attach Cable, 2m, 30 AWG, PVC Jacket: This is a passive copper direct attach cable (DAC) terminated QSFP28 to QSFP28 for point-to-point 100 Gigabit Ethernet links. The cable is a fixed-length integrated assembly with permanently terminated connectors; it is not a transceiver paired with a separate twinax. This is a Refurbished unit, tested by T.E.S IT-SOLUTIONS. NVIDIA P/N reference: 980-9I621-00C002.
Engineering Context
The MCP1600-C002 carries 4 lanes x 25Gb/s NRZ across 30 AWG copper conductors entirely passively, drawing zero power from the host port. At 2 meters it is purpose-built for short, in-rack 100GbE point-to-point connections where it offers the lowest latency and lowest cost per link compared to optical transceivers plus fiber. The PVC outer jacket is suitable for general data center deployment in trays and racks; for plenum or strict fire-code environments, an LSZH variant should be sourced separately.
Deployment & Use Cases
ToR-to-server 100GbE links between a Spectrum switch and ConnectX-5 / ConnectX-6 Dx hosts in the same rack. Spine-leaf interconnects between two adjacent switches at short reach. NVMe-oF storage links from compute hosts to all-flash arrays. Lab and integration test fixtures requiring deterministic 100GbE behavior without optical fiber handling.

Compatibility & Hard Constraints
Compatible with NVIDIA Spectrum switches (SN2000, SN3000, SN4000 series) and ConnectX-4 / ConnectX-5 / ConnectX-6 Dx EN adapters in 100GbE Ethernet mode. Most third-party 100GbE QSFP28 ports that accept passive DACs (Arista, Cisco Nexus, Dell PowerSwitch) link up, subject to vendor cable allowlists in the switch OS. Not for InfiniBand EDR ports unless the host explicitly supports VPI Ethernet mode — this is sold as an Ethernet 100GbE DAC. Not a breakout cable; does not support 4x25GbE breakout. Not rated for plenum without an LSZH-jacketed variant. Fixed 2m length.
