## Summary description

BlueOptics DAC passive cable for high-speed InfiniBand and fibre optic connectivity. Length 1 m, black, with QSFP-DD connector on one end and two QSFP56 connectors on the other. Designed for direct-attach connections between QSFP-DD and dual QSFP56 ports in switches, servers or adapters; suitable for short-reach data center interconnects.

## Long description

BlueOptics InfiniBand/fibre optic DAC cable 1 m QSFP-DD to 2x QSFP56 Black is a passive direct-attach copper cable designed for short-reach, high-bandwidth connections in data centres and server racks. It features a single QSFP-DD connector on one end and two QSFP56 connectors on the other, enabling a 400 Gbit/s link or two 200 Gbit/s lanes where hardware and protocols support these modes. The cable is 1 metre long, black, and intended for direct connections between switches, servers, adapters or neighbouring rack equipment following common MSA physical interface conventions.
Advantages
The passive DAC design provides low-latency, high-throughput connectivity without additional transceivers or optical modules. A single-cable solution with QSFP-DD to dual QSFP56 terminations simplifies cabling between devices that support 400GBase-CR8 or 2x200GBase-CR4 topologies. The fixed 1 m length reduces clutter in rack environments while offering consistent electrical characteristics for short-distance interconnects. Compatibility with standard QSFP-DD and QSFP56 form factors ensures straightforward installation in supported ports.
Suitable for
Short-reach connections between switches and servers within the same rack or adjacent racks
High-performance InfiniBand or Ethernet links requiring 400G or dual 200G lanes
Top-of-rack and aggregations where passive twinax cabling is preferred
Key specifications
Cable type: Direct Attach Copper (DAC), passive
Length: 1 m
Connector configuration: QSFP-DD (single) to 2× QSFP56
Maximum aggregated data rate: up to 400 Gbit/s (or 2×200 Gbit/s depending on host and switch support)
Colour: Black
Weight: 0.35 kg
How to use
Insert the QSFP-DD connector into a compatible QSFP-DD port and the two QSFP56 connectors into their respective QSFP56 ports on the target device. Ensure both endpoints support the desired link configuration (400GBase-CR8 or 2x200GBase-CR4) and that firmware or driver settings on network adapters and switches are configured for the expected lane and speed negotiation. Handle the cable by the connector housings during insertion and removal to avoid strain on the assembly, and route the cable to avoid sharp bends or crushing within the rack.
Usage recommendations
Use this passive DAC for short-distance, high-bandwidth links inside racks or between adjacent racks. Verify host and switch compatibility with QSFP-DD to dual QSFP56 passive connections and confirm support for 400G or split-200G modes in device documentation before deployment. Avoid extended distances beyond typical DAC range and operate within the environmental limits specified by connected hardware.
