Mellanox MCP7H50-H002R26: 200G HDR to Dual 100G HDR100 Breakout DAC Cable

Product Overview

The Mellanox MCP7H50-H002R26 is a high-performance Direct Attach Copper (DAC) breakout solution that serves as a superior alternative to traditional passive fiber cable systems. This innovative interconnect efficiently converts a single 200Gb/s InfiniBand HDR port into two independent 100Gb/s HDR100 connections, offering data centers an optimal combination of performance, power efficiency, and cost-effectiveness for high-density networking environments.

Technical Specifications

Technology Implementation

This advanced passive fiber cable alternative utilizes sophisticated 4×50Gb/s PAM4 modulation technology, delivering exceptional signal integrity across all transmission channels. The solution fully complies with InfiniBand Trade Association (IBTA) HDR standards and incorporates SFF-8665 and SFF-8636 specifications for seamless integration and comprehensive management via I²C interface, providing a robust alternative to traditional fiber optic systems.

Operational Methodology

The MCP7H50-H002R26 functions as an intelligent passive electrical bridge, efficiently routing high-speed signals from a single QSFP56 connector (supporting 200G HDR) to two independent QSFP56 connectors (each supporting 100G HDR100). This sophisticated passive fiber cable replacement maintains exceptional signal integrity through precision impedance-matched copper conductors (100Ω characteristic impedance) and advanced shielding technologies that effectively minimize crosstalk and electromagnetic interference, ensuring reliable data transmission.

Application Environments

This high-density interconnect solution is ideally suited for modern infrastructure requirements:

Competitive Advantages

The MCP7H50-H002R26 offers significant advantages over both active optical cables and previous-generation copper solutions:
