Mellanox MCP7H50-H002R26 HDR to 2x HDR100 Direct Attach Copper Splitter Cable

1. Product Overview

The Mellanox MCP7H50-H002R26 is a high-performance, passive copper Direct Attach Cable (DAC) designed for 200Gb/s InfiniBand HDR systems. It splits a single 200Gb/s HDR port into two independent 100Gb/s HDR100 ports, providing a cost-effective and power-efficient solution for high-density data center interconnects. This passive fiber cable alternative ensures reliable, high-speed data transmission with minimal latency.

2. Key Characteristics

• 200Gb/s HDR to 2x100Gb/s HDR100 bidirectional data rate
• 4x50Gb/s PAM4 modulation per port
• Low power consumption (<0.1W)
• Hot-pluggable, RoHS compliant, LSZH jacket
• Lead-free and halogen-free PCB design
• 2-meter length with 26AWG wire gauge

3. Technology & Standards

Compliant with InfiniBand HDR standards, SFF-8665, and SFF-8636 for I²C management. Supports PAM4 modulation for enhanced data integrity and bandwidth efficiency.

4. Working Principle

The cable passively routes electrical signals from one QSFP56 connector (200G HDR) to two QSFP56 connectors (100G HDR100). Each pair of copper conductors transmits high-speed data with minimal signal degradation, leveraging impedance-matched traces and robust shielding.

5. Applications

Ideal for hyperscale data centers, high-performance computing (HPC), artificial intelligence clusters, and storage area networks (SANs). Enables flexible topology design and efficient bandwidth utilization.

6. Specifications

7. Advantages

• Lower latency and power consumption compared to active optical cables
• Superior signal integrity with impedance-controlled design
• Robust mechanical construction with LSZH jacket for safety
• Backward compatible with previous InfiniBand generations

8. Service & Support

1-year limited warranty. Global technical support and integration services available. Lead time typically 2–4 weeks.

9. Frequently Asked Questions

Q: Is this cable compatible with Mellanox switches?
A: Yes, it is fully compatible with Mellanox InfiniBand HDR systems.

Q: What is the maximum bend radius?
A: 34mm for single bend, 68mm for repeated bends.
