NVIDIA Mellanox 100G QSFP28 to 4x25G SFP28 DAC Breakout Cable 3 Meter MCP7F00-A003R26N

The NVIDIA Mellanox MCP7F00-A003R26N is a high-performance 100GbE QSFP28 to 4x25GbE SFP28 Passive Direct Attach Copper (DAC) Breakout Cable designed for data centers, cloud computing environments, high-performance computing (HPC), and enterprise networking deployments.

This passive copper breakout cable converts a single 100GbE QSFP28 port into four independent 25GbE SFP28 connections, providing a low-latency and cost-effective alternative to optical transceivers while maintaining excellent signal integrity and reliability. The passive twinax design requires no external power, reducing both operating costs and complexity.

The 3-meter (9.84 ft) cable utilizes 26 AWG twinax copper conductors, optimized for reliable short-distance, high-bandwidth interconnects between switches, servers, storage systems, and network adapters.
