Product information

Description

BlueOptics InfiniBand/fibre optic DAC cable QSFP-DD to 2x QSFP56, 1 m, Black is a direct attach copper (DAC) twinax cable designed to interconnect high-speed networking devices. The cable features a single QSFP-DD plug on one end and two QSFP56 plugs on the other, with a 1 m length and a black housing. It is intended for short-reach electrical connections between switches, servers and network interface cards that support QSFP-DD and QSFP56 form factors in data centre and high-performance computing environments.

Advantages

This DAC cable provides a compact, low-latency physical link without the need for transceivers, offering a straightforward cabling option for rack-to-rack or intra-rack interconnects. Passive twinax construction reduces power consumption compared with active optical solutions for short distances. The QSFP-DD to dual QSFP56 pinout enables splitting a single high-density port into two 200G-capable QSFP56 endpoints where supported by host hardware, simplifying consolidation and port aggregation in dense deployments.

Suitable for

  • Short-reach connections between switches and top-of-rack devices
  • Interconnects between servers and NICs supporting QSFP-DD and QSFP56
  • High-performance computing (HPC) clusters and data centre aggregation
  • Rack-to-rack cabling within the same equipment room or adjacent racks

Key specifications

  • Cable type: Direct Attach Copper (DAC), passive twinax
  • Cable length: 1 m
  • Connector configuration: QSFP-DD (single) to 2× QSFP56 (dual)
  • Colour: Black
  • Weight: 0.35 kg

How to use

Ensure both ends and the host ports are compatible with QSFP-DD and QSFP56 standards and that the target devices support splitting or breakout functionality where required. Power down or follow hot-plug guidance of your hardware vendor before inserting the cable. Align the QSFP-DD connector with the port and insert until it seats; repeat for the two QSFP56 connectors. Verify link lights and device diagnostics to confirm a successful connection and correct lane mapping as per your switch or NIC configuration.

Usage recommendations

Use this 1 m passive DAC for short-distance, high-bandwidth links inside racks or between adjacent racks. Avoid routing the cable near strong electromagnetic interference sources, and observe bend-radius limits and secure strain relief to maintain signal integrity and mechanical reliability.
