Mellanox MCP1650-H002E26 200Gbps QSFP56 Direct Attach Copper Cable

1. Product Overview

The Mellanox MCP1650-H002E26 is a high-performance, cost-effective passive Direct Attach Copper (DAC) cable designed for 200Gb/s InfiniBand HDR applications. It serves as an efficient alternative to optical fiber solutions, offering high bandwidth and low power consumption for data center interconnects.

2. Key Characteristics

• Compliant with InfiniBand HDR standards
• Data rate up to 200Gb/s using 4x50Gb/s PAM4 modulation
• Low power consumption: <0.1W
• Hot-pluggable QSFP56 form factor
• RoHS compliant with LSZH (Low Smoke Zero Halogen) jacket
• Lead-free and halogen-free PCB design

3. Technology & Standards

The cable complies with SFF-8665 and SFF-8636 standards, ensuring interoperability with industry-standard QSFP56 ports. It uses PAM4 modulation for high-speed data transmission and features an integrated EEPROM for device identification and management via I²C.

4. Working Principle

The passive copper cable transmits electrical signals directly between QSFP56 ports without active components. Each cable contains eight copper pairs, each supporting up to 50Gb/s. The host system reads cable information from the EEPROM to ensure compatibility and performance.

5. Applications

• Data center spine-leaf architecture
• High-performance computing (HPC) clusters
• Cloud infrastructure and enterprise networking
• Storage area networks (SAN)
• AI and machine learning platforms

6. Specifications

7. Advantages

• Lower latency compared to optical solutions
• Cost-effective for short-reach applications
• No additional power required for signal amplification
• High reliability with rigorous production testing
• Backward compatible with QSFP28 and QSFP+ ports with adapter support

8. Service & Support

All Mellanox DAC cables come with a 1-year limited hardware warranty covering repair or replacement. We offer 24/7 customer support and technical consultation to ensure seamless integration and operation.

9. Frequently Asked Questions (FAQ)

Q: Is this cable compatible with QSFP28 ports?
A: Yes, with appropriate adapters or mode configuration, it can be used in QSFP28 ports supporting 100Gbps.

Q: What is the maximum bend radius?
A: The minimum bend radius is 5x the cable diameter for single bends and 10x for repeated bends.

Q: Does it require drivers?
A: No, it is a passive copper cable and does not require additional drivers.

Q: What is the typical BER?
A: The Bit Error Rate is better than 1E-15 when used with Mellanox HDR systems.

10. Precautions

• Avoid sharp bends beyond the specified radius to prevent signal degradation.
• Ensure operating temperature and humidity are within specified ranges.
• Use only with compatible Mellanox or certified third-party equipment.
• Follow ESD precautions during handling and installation.
