Product information

Description

The BlueOptics FN-CABLE-QSFP56-DAC-L50CM-BL is a direct-attach copper (DAC) cable with QSFP56 connectors at both ends and a fixed length of 0.5 m. Designed for InfiniBand and high-performance networking environments, this cable provides a short, low-latency interconnect option for switch-to-switch, switch-to-server, or server-to-server links where reliable, high-bandwidth transmission is required. The black outer jacket offers a discreet appearance in rack environments.

Advantages

This DAC cable delivers low latency and stable signal integrity over a short distance, supporting high-throughput connections without the need for optical transceivers. The QSFP56 connectors provide compatibility with equipment that accepts 56 Gbps per lane QSFP56 modules, enabling dense, high-performance links in data center topologies. Its compact 0.5 m length reduces cable clutter and simplifies cable management in tight rack spaces.

Suitable for

  • Short-reach interconnects in data center racks
  • InfiniBand fabrics and HPC cluster links
  • Switch-to-server and server-to-server high-bandwidth connections
  • Environments where low latency and reduced cabling are priorities

Key specifications

  • Cable type: Direct-attach copper (DAC)
  • Cable length: 0.5 m
  • Connector type: QSFP56 on both ends
  • Typical use: InfiniBand and high-performance networking
  • Weight: 0.15 kg
  • Colour: Black

How to use

Ensure both devices support QSFP56 direct-attach connections and that ports are powered down or in a safe state before installation if recommended by the equipment manufacturer. Align the QSFP56 connector with the port and insert until the latch engages, confirming a secure mechanical and electrical connection. For removal, release the latch mechanism and pull the connector straight out to avoid damaging ports. Use appropriate handling procedures to avoid excessive bending near the connector ends.

Usage recommendations

For optimal performance, use this 0.5 m DAC cable for short, high-bandwidth links within a rack or between adjacent racks. Avoid routing the cable near sources of strong electromagnetic interference and do not exceed the recommended bend radius to maintain signal integrity. Check compatibility with your switches, host adapters, or interconnect hardware to ensure supported data rates and connector form factor.
