Identity & Definition
This enterprise Ethernet DAC splitter cable, the NVIDIA Mellanox MCP7H60-C02A, is a 2.5-meter passive DAC (Direct Attach Copper) splitter cable that breaks out a single 200GbE QSFP-DD port into two independent 100GbE QSFP28 connections. This is an Ethernet-only breakout cable, not an InfiniBand cable. This is a splitter (1-to-2), not a straight cable. Condition: Refurbished — tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MCP7H60-C02A enables migration from 200GbE QSFP-DD infrastructure to existing 100GbE QSFP28 devices. A single QSFP-DD 200GbE port splits into two independent 100GbE QSFP28 links using 4x 50Gb/s PAM4 signaling per 100GbE leg. At 2.5 meters, this cable extends reach beyond the 2m C002 variant, enabling connections to adjacent racks. As passive copper, it consumes zero power and adds minimal latency. The 2.5m length is near the practical passive copper limit for 200GbE — for longer distances, active optical breakout is required.
Deployment & Use Cases
Connecting 200GbE Spectrum-3/Spectrum-4 spine switches to 100GbE leaf switches or servers via breakout. Adjacent-rack connectivity where 2m cables (MCP7H60-C002) are too short. Migrating 100GbE infrastructure to 200GbE switches incrementally. Maximizing port utilization on QSFP-DD switches in enterprise and cloud data centers.

Compatibility & Hard Constraints
Ethernet Only: Not for InfiniBand use. QSFP-DD to QSFP28: Not reversible — cannot combine two 100GbE into 200GbE. Switch Breakout Mode: QSFP-DD port must be configured for 2x100G breakout mode. Passive Copper: 2.5m is near the maximum passive reach for 200GbE. For longer distances, active optical breakout required. Compatible With: Spectrum-3, Spectrum-4, and other switches with QSFP-DD 200GbE breakout support. Predecessor: MCP7H60-C002 (2m variant). Successor: Active optical 200G breakout cables for longer reach.
