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
Q: What is the maximum distance supported by this DAC solution?
A: The MCP7H50-H002R26 is optimized for short-reach applications up to 3 meters, making it ideal for rack-scale and adjacent-rack connectivity.
Q: Is this cable compatible with non-Mellanox equipment?
A: While optimized for Mellanox systems, this passive fiber cable alternative follows industry standards and is generally compatible with other vendors' equipment that supports InfiniBand HDR and compatible QSFP56 interfaces.
Q: What does the "R26" designation indicate in the model number?
A: The "R26" specifies the cable's wire gauge (26 AWG) and rainbow pulltab color for easy identification in high-density environments.
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
