NVIDIA Mellanox MCP1600-C001 1-Meter 100GbE Passive Copper Cable QSFP28 (Lot of 3): This listing is for a lot of three (3) units of the MCP1600-C001 — a 1-meter QSFP28-to-QSFP28 passive copper Direct Attach Cable (DAC) supporting 100GbE Ethernet. Each cable uses 30 AWG copper conductors with a PVC jacket. These are passive (un-amplified) DACs, not active copper or active optical assemblies. The units are refurbished.
Engineering Context
The MCP1600-C001 uses 4x 25Gb/s NRZ lanes for an aggregate 100Gb/s line rate per the 100GbE specification. Passive copper at 1m is the lowest-latency, lowest-power interconnect option for top-of-rack server-to-switch links — zero added latency from optics or DSP and roughly 0.1W per end. The 30 AWG conductor gauge is appropriate for short reach where insertion loss budget is not critical. PVC jacket is used for cost-effective deployments not subject to LSZH requirements.
Deployment & Use Cases
Top-of-rack QSFP28 server-to-switch links in 100GbE Ethernet fabrics. Spectrum SN2000 series leaf-switch uplinks. ConnectX-4 / ConnectX-5 100GbE host adapter connections to ToR switches. Storage-to-server short-reach 100GbE links within a single rack. Lots of 3 are well suited for spare-pool stocking or small server cluster builds.

Conductor Gauge: 30 AWG
Jacket: PVC
Protocol: 100GbE Ethernet
Lot Quantity: 3 cables per listing
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with NVIDIA Spectrum SN2000 series 100GbE Ethernet switches and ConnectX-4 / ConnectX-5 100GbE host adapters. Also compatible with EDR InfiniBand ports (100Gb/s) on Switch-IB 2 (SB7800). Not a breakout cable — this is point-to-point QSFP28 to QSFP28. For 4x25G breakout splits, use a dedicated MCP7F00 breakout DAC. Not compatible with HDR (200Gb/s) QSFP56 or NDR (400Gb/s) ports. PVC jacket means the cable is not LSZH-rated; for LSZH environments, use the MCP1600-C001E30 variant. Fixed 1m length.
