BlueOptics BlueLAN QSFP56 Direct Attach Cable 200Gb/s InfiniBand HDR, 1 m, 30AWG, compatible with Infortrend 9624CM200CAB0-003

BlueOptics BlueLAN QSFP56 Direct Attach Cable provides 200Gb/s InfiniBand HDR connectivity over a 1 m copper assembly. Designed for short-reach, high-throughput links, this QSFP56 cable uses 30AWG conductors and fits QSFP56 ports on switches, NICs and storage controllers. It is specified as compatible with Infortrend 9624CM200CAB0-003 and is intended for dense rack and data centre environments where low-latency, high-bandwidth interconnects are required.

Advantages

The cable delivers a single-cable solution for 200Gb/s InfiniBand HDR links with a 1 m length that simplifies cabling in top-of-rack and cluster deployments. With 30AWG conductors and QSFP56 form-factor termination, it offers a compact, low-latency physical connection that reduces power and port-occupancy compared with optical transceivers plus fiber. Compatibility with standard QSFP56 ports and specified support for Infortrend hardware helps ensure interoperability in mixed-vendor environments.

Suitable for (tasks / use cases)

• Short-reach 200Gb/s connections between switches or leaf/spine stages in data centres
• Direct attach links between servers and high-performance NICs for HPC clusters
• Interconnects between storage controllers and switches in SAN or InfiniBand fabrics
• Racks and patching within top-of-rack or middle-of-row deployments where 1 m length is appropriate

When it may not be suitable

This copper direct-attach cable is intended for short-distance links; it is not suitable for long-reach connections or situations that require fibre-optic links for extended distances. Environments that require hot-pluggable optical modules, longer runs beyond the electrical reach of 30AWG copper, or specific vendor-locked transceiver diagnostics may require alternative solutions.

Key specifications

• Data rate: 200 Gb/s (InfiniBand HDR)
• Connector / form factor: QSFP56
• Length: 1 m
• Conductor gauge: 30 AWG
• Media type: Copper direct-attach cable (DAC)
• Typical use: Short-reach, high-bandwidth interconnects

How to use

Insert each QSFP56 plug into the corresponding QSFP56 port on your switch, NIC or storage controller until the latch engages. Ensure both ends are seated fully and that connected equipment is powered according to manufacturer guidelines. For best results, route the cable to avoid sharp bends and excessive mechanical stress; maintain recommended bend radius for 30AWG assemblies and avoid tight cable bundles that increase heat. Verify link status at the host or switch management interface after installation and confirm negotiated link speed and connectivity.

What to consider before purchase

• Confirm that your equipment supports QSFP56 DACs and 200Gb/s InfiniBand HDR operation
• Check that 1 m cable length fits your rack or chassis layout and cable management
• Ensure vendor compatibility or confirmed interoperability with Infortrend devices if required
• Assess whether copper DAC reach and thermal behaviour are suitable for your deployment

Usage recommendations

Use the BlueLAN QSFP56 DAC for direct short links inside racks and across adjacent racks where 1 m length is sufficient; avoid torsion and tight bends, and verify link parameters in system interfaces after installation to ensure full 200Gb/s operation.
