BlueOptics QSFP Direct Attach Cable 2m, 56Gbps, InfiniBand FDR, 28AWG

BlueOptics QSFP Direct Attach Cable 2m is a pre-terminated copper interconnect designed for short-reach, high-speed links. The 2 meter cable uses a QSFP connector form factor and supports an aggregate data rate up to 56 Gbps, making it suitable for InfiniBand FDR environments and other applications that require low-latency, high-throughput connections between switches, network interface cards and storage systems.

Advantages

This direct attach cable provides a cost-effective, low-power alternative to optical transceivers for short distances. Construction with 28AWG conductors delivers signal integrity for 56 Gbps aggregate throughput while the QSFP termination ensures compatibility with equipment that accepts QSFP direct attach solutions. The fixed-length, pre-terminated design reduces installation time and simplifies rack-to-rack and intra-rack cabling.

Suitable for

• Data centre rack-to-rack connections
• High-performance computing (HPC) clusters
• Server-to-switch and switch-to-switch links requiring InfiniBand FDR performance
• Short-reach storage networking and SAN interconnects

Key specifications

• Cable type: QSFP direct attach copper (DAC)
• Length: 2 meters
• Aggregate data rate: up to 56 Gbps
• Conductor gauge: 28 AWG
• Application: InfiniBand FDR and compatible high-speed interconnects
• Form factor: QSFP termination for four-lane, high-density ports

How to use

Insert each QSFP connector into the corresponding QSFP port on the devices to be connected, ensuring latch engagement and correct orientation. Verify that both ends are properly seated and that the host devices recognize the link. For best performance, maintain recommended bend radii and avoid excessive strain on the cable assembly during routing. No additional configuration is required beyond standard interface setup on the connected equipment.

Usage recommendations

Use this 2m QSFP direct attach cable for short-distance links inside racks or between adjacent racks where optical transceivers are not necessary. Avoid installation in pathways with tight bends or mechanical stress; maintain clean connector interfaces and follow the equipment manufacturer’s guidelines for QSFP modules and InfiniBand FDR deployments.
