## Summary description

The Mellanox MCP1650-H001E30 is a 1-meter InfiniBand/fibre optic cable featuring a QSFP56 connector. This high-performance cable is designed for data centers and high-speed networking applications, providing reliable connectivity with minimal latency. Its robust construction ensures durability and longevity, making it an ideal choice for demanding environments.

## Long description

The Mellanox MCP1650-H001E30 is a 1-meter QSFP56 direct attach cable designed for HDR 200Gb/s InfiniBand and high-speed Ethernet interconnects. Intended for short-reach links inside racks and between adjacent racks, this passive copper cable provides a straightforward, low-latency connection between QSFP56 ports. Its robust jacket and factory-tested construction deliver reliable performance in data center and high-performance computing environments while eliminating the need for additional power found in active optical solutions.
Advantages
This passive DAC cable offers 200Gb/s per link throughput with minimal latency and reduced power consumption compared with active optical alternatives. The QSFP56 interface ensures compatibility with equipment that supports QSFP56 ports, and the cable’s passive design minimizes electromagnetic interference (EMI) emissions. Factory testing and durable materials contribute to consistent out-of-the-box performance and long service life in dense rack deployments.
Suitable for
Short-reach server-to-switch or switch-to-switch connections within a rack
High-performance computing (HPC) clusters and InfiniBand fabrics
Data center top-of-rack and middle-of-row interconnects
Low-latency storage networks and NVMe over Fabrics setups
Key specifications
Connector type: QSFP56 to QSFP56
Data rate: up to 200 Gb/s aggregate per link (HDR 200Gb/s)
Length: 1.0 meter
Medium: passive copper direct attach cable
Typical use: short-reach in-rack and adjacent-rack connections
EMI: reduced emissions due to passive design
How to use
Insert each QSFP56 plug into compatible QSFP56 ports on the devices to be connected, ensuring the latch mechanism engages. Use the 1 m length for short in-rack or adjacent-rack cabling to maintain signal integrity and avoid excess slack. No external power or transceivers are required because this is a passive direct attach cable. After installation, verify link status and negotiated speed in the host or switch management interface.
Usage recommendations
For optimal performance, use this cable for short-distance connections where a passive copper DAC is supported by both endpoints. Avoid sharp bends and excessive tensile stress on the cable; maintain recommended bend radius and secure routing within cable management panels. If higher flexibility or longer reach is required, consider active optical cables or fiber solutions that match the same QSFP56 interface.
