How this unit is built
Recovered from end-of-life equipment, inspected and tested before it ships.
See the production flowNVIDIA Mellanox MCP1600-C01B 100GbE QSFP28 Passive Direct Attach Copper Cable, 1.75m: This is a 1.75-meter passive copper Direct Attach Cable (DAC) terminated with QSFP28 connectors at both ends, designed for 100GbE Ethernet point-to-point connections. It is a fixed-length copper assembly, not an active optical cable and not a transceiver pair. This is a refurbished unit.
Engineering Context
The MCP1600-C01B carries 100Gb/s of Ethernet traffic as four 25Gb/s NRZ lanes over twinax copper pairs. Passive DAC contains no active electronics, drawing zero power and adding minimal latency compared to optical alternatives. The 1.75m length is suited to top-of-rack switch to server connections within a single rack. The Long-Short Pulltab Design improves removal in high-density 1U/2U switch port configurations. The PVC jacket is standard-grade for general data center deployments.
Deployment & Use Cases
Top-of-Rack 100GbE switch to server uplinks within a single rack. Connecting NVIDIA Spectrum SN2000/SN3000/SN4000 series switches to ConnectX-4, ConnectX-5, or ConnectX-6 Dx adapters. Spine-leaf interconnects on adjacent racks where 1.75m provides sufficient reach. Storage fabrics linking JBOFs and NVMe-oF targets to compute hosts.
Technical Specifications
Compatibility & Constraints
Compatible with NVIDIA Spectrum SN2000/SN3000/SN4000 switches and ConnectX-4/5/6 Dx EN adapters configured for 100GbE. Requires both end ports configured for 100GbE Ethernet. Not compatible with 40GbE-only QSFP+ ports. Not a breakout cable; this is a direct QSFP28-to-QSFP28 1:1 link and does not support 4x25G fan-out. Fixed 1.75m length; passive copper does not support reach extension.
Frequently Asked Questions (FAQ)
Q. What is the MCP1600-C01B?
The MCP1600-C01B is a 1.75m passive copper DAC with QSFP28 connectors on both ends, rated for 100GbE Ethernet.
