Mellanox MCP7H50-H002R26: High-Density 200G HDR to Dual 100G HDR100 Splitter Cable

Product Overview

The Mellanox MCP7H50-H002R26 represents a cutting-edge passive fiber cable alternative, engineered to transform a single 200Gb/s InfiniBand HDR port into two independent 100Gb/s HDR100 connections. This high-performance Direct Attach Copper (DAC) solution offers data centers a power-efficient, cost-effective method for expanding connectivity without compromising speed or reliability.

Technical Specifications

Advanced Technology

This innovative passive fiber cable solution implements 4×50Gb/s PAM4 modulation technology, ensuring exceptional signal integrity across all connected channels. The cable assembly complies with InfiniBand Trade Association (IBTA) HDR standards and incorporates SFF-8665 and SFF-8636 specifications for seamless integration and management via I²C interface.

Operational Principle

The MCP7H50-H002R26 operates as a passive electrical bridge, intelligently routing high-speed signals from a single QSFP56 connector (supporting 200G HDR) to two separate QSFP56 connectors (each supporting 100G HDR100). This sophisticated passive fiber cable alternative maintains signal integrity through precisely impedance-matched copper conductors (100Ω characteristic impedance) and advanced shielding technologies that minimize crosstalk and electromagnetic interference.

Application Scenarios

This high-performance interconnect solution is ideally suited for:

• Hyperscale data center spine-leaf architectures
• High-performance computing (HPC) clusters
• Artificial intelligence and machine learning infrastructure
• Storage area networks (SAN) and network-attached storage (NAS)
• Financial trading systems requiring ultra-low latency

Competitive Advantages

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

• Cost Efficiency: Approximately 30-40% lower cost than equivalent active optical solutions
• Power Savings: Consumes less than 0.1W compared to 1.5-2.5W for active cables
• Enhanced Reliability: Passive design eliminates active components that can fail
• Reduced Latency: Electrical signal transmission provides lower latency than optical conversion
• Environmental Benefits: LSZH jacket and halogen-free construction improve safety

Frequently Asked Questions

Installation & Handling Guidelines

To ensure optimal performance and longevity:

• Maintain minimum bend radius of 34mm for single bends and 68mm for repeated bends
• Avoid sharp bends especially near connector interfaces
• Ensure proper ESD precautions during handling and installation
• Verify compatibility with host system firmware and drivers
• Operate only within specified temperature and humidity ranges
• Regularly inspect connectors for debris or damage before installation
