MCP1650-H002E26 HDR 200Gb/s QSFP56 Direct Attach Copper Cable

1. Product Overview

The Mellanox MCP1650-H002E26 is a high-performance, passive Direct Attach Copper (DAC) cable engineered for 200Gb/s InfiniBand HDR and high-speed Ethernet applications. This QSFP56 form factor cable offers a cost-efficient, low-power solution for short-reach data center interconnects, delivering exceptional signal integrity and reliability. It is an ideal optical fiber cable alternative for in-rack and adjacent-rack connections.

2. Key Characteristics

• Compliant with InfiniBand HDR standard
• Supports data rates up to 200 Gb/s via 4x50G PAM4 modulation
• Hot-pluggable QSFP56 form factor
• Low power consumption (< 0.1W)
• RoHS and LSZH (Low Smoke Zero Halogen) compliant
• Halogen-Free and Lead-Free PCB construction

3. Technology & Standards

This passive fiber cable solution adheres to industry standards including SFF-8665 for mechanical specifications and SFF-8636 for I²C management interface. It uses PAM4 modulation to achieve high data rates with low power consumption and is designed to work seamlessly with Mellanox InfiniBand HDR systems.

4. Working Principle

The MCP1650-H002E26 is a passive copper cable containing eight high-speed copper pairs, each capable of transmitting data at 50 Gb/s. The cable assembly incorporates an EEPROM that stores vital product information, accessible by the host system for identification and configuration. Unlike active optical cables, this optical fiber cable alternative relies on electrical signal transmission over copper, making it ideal for short-distance, high-speed links.

5. Applications

Ideal for high-performance computing (HPC), cloud data centers, enterprise networking, and storage area networks (SANs). Commonly deployed for top-of-rack (ToR) switching, spine-leaf architectures, and interconnecting servers and storage systems within and across racks.

Its passive copper cable design ensures simplicity and reliability, making it a superior alternative to standard optical fiber cable in short-reach applications.

8. Service & Support

All Mellanox DAC cables come with a 1-year limited hardware warranty covering repair or replacement. Our company provides 24/7 customer consultation and technical support, ensuring prompt assistance and reliable service.

9. Frequently Asked Questions

Q: What is the maximum distance for this cable?
A: This passive DAC cable is designed for short reaches up to 2-3 meters, ideal for within-rack connections.

Q: Is this cable compatible with 100GbE QSFP28 ports?
A: While electrically similar, compatibility depends on the specific switch and firmware. It is designed for QSFP56 200G ports.

Q: Does it require external power?
A: No, this is a passive cable and does not require additional power.

10. Precautions

• Ensure minimum bend radius: 47mm for single bend, 94mm for repeated bends.
• Operate within specified temperature and humidity ranges.
• Verify compatibility with host hardware and software.
• Avoid bending near connectors to prevent damage.
