Product information

Description

BlueOptics InfiniBand/fibre optic DAC cable 1 m QSFP-DD to 2×QSFP56 Black is a passive direct attach copper (DAC) cable designed for short-reach high-speed connections in data centre racks. With a 1 m length and QSFP-DD to dual QSFP56 mating, it enables direct electrical linkage between a single QSFP-DD port and two QSFP56 ports in switches, servers or network interface cards that support compatible port types.

Advantages

This DAC cable offers a compact, low-latency connection for 400G-capable systems while avoiding the need for separate transceivers and fibre patching for short distances. The pre-terminated QSFP-DD to 2×QSFP56 configuration simplifies cabling density in rack deployments and reduces insertion points compared with multiple discrete cables. Its passive twinax construction provides consistent electrical signal transmission for short links and requires no external power or cooling.

Suitable for

  • Direct server-to-switch connections inside racks
  • Interconnections between adjacent racks in a data centre
  • High-speed InfiniBand or Ethernet fabrics using QSFP-DD and QSFP56 ports
  • Top-of-rack aggregation where short-reach, high-bandwidth links are needed

Key specifications

  • Cable type: Direct Attach Copper (DAC)
  • Cable length: 1 m
  • Connector 1: QSFP-DD
  • Connector 2: 2× QSFP56
  • Rated bandwidth: supports 400G-capable configurations (400 Gbit/s topology dependent)
  • Product colour: Black
  • Weight: 0.35 kg

How to use

Insert the QSFP-DD plug into the host QSFP-DD port and insert the two QSFP56 plugs into the corresponding QSFP56 ports, ensuring connectors are fully seated and latches engaged. Verify the host devices support passive DAC connections between QSFP-DD and QSFP56 form factors and confirm port speed/port mapping in device firmware or management software. Follow standard electrostatic discharge (ESD) precautions when handling and avoid sharp bends; observe each device’s hot-plug and link training procedures during installation and removal.

Usage recommendations

Use this DAC for short-reach links within the same rack or to adjacent racks; verify compatibility with your hardware vendor’s supported DAC types and firmware notes for QSFP-DD to QSFP56 connectivity. Avoid using outside the intended short-range environment and keep the cable routing free from mechanical stress and excessive heat sources.
