NVIDIA Mellanox 100GbE QSFP28 DAC Cable 2m

The NVIDIA Mellanox MCP1600-C002 is a 100GbE passive copper Direct Attach Cable (DAC) measuring 2 metres in length, terminated at both ends with QSFP28 connectors. Operating as a passive twinaxial assembly, the cable requires no active signal conditioning circuitry, drawing negligible power from the host port and eliminating the thermal and reliability concerns associated with active components. The QSFP28 form factor carries four 25 Gbps NRZ electrical lanes in each direction, aggregating to 100 Gbps full-duplex throughput in compliance with the IEEE 802.3bj and 100GBASE-CR4 standards.

Designed for high-density rack and row-level interconnects, the MCP1600-C002 is optimised for use with NVIDIA ConnectX-4, ConnectX-5, and ConnectX-6 series network adapters, as well as compatible 100G Ethernet switches in the Spectrum product line. The cable assembly integrates digital diagnostics monitoring (DDM/DOM) data accessible via the QSFP28 management interface, allowing network operations teams to inspect real-time signal integrity metrics without disrupting live traffic. The passive copper construction makes the cable fully interoperable with any IEEE 802.3bj-compliant 100GBASE-CR4 port.

As a passive DAC, the MCP1600-C002 is best suited for intra-rack and adjacent-rack connections where reach does not exceed two metres and power efficiency is a priority. It is a practical choice for hyperscale compute clusters, GPU server interconnects, top-of-rack switch uplinks, and storage fabric deployments where high port density and low latency are essential. The assembly ships with an integrated EEPROM containing vendor identification data that enables plug-and-play recognition on NVIDIA-branded platforms as well as a broad range of third-party 100G switches and adapters.

Ideal for

• Intra-rack server-to-ToR switch uplinks in hyperscale data centre deployments requiring 100GbE at minimal power draw
• GPU-to-GPU and GPU server-to-network fabric connections in AI and HPC training clusters where sub-2-metre reach is sufficient
• NVMe-oF and high-performance storage fabric interconnects between compute nodes and all-flash storage arrays within the same rack
• High-density leaf-spine interconnects between co-located top-of-rack switches when port-to-port distance is within two metres
• Test and validation lab environments requiring repeatable, low-latency 100GbE copper links between servers and network equipment
• Blade server chassis and modular data centre platforms where passive copper DAC cables reduce per-port power consumption compared to optical transceivers
