InfiniBand/fibre optic cable BlueOptics AXLC761-10000S-BL 1 m QSFP Male/Male

The BlueOptics AXLC761-10000S-BL is a 1 m InfiniBand/fibre optic cable with QSFP connectors on both ends, designed for high-speed data transmission in data centers and high-performance computing environments. This cable supports 40GBase-CR4 applications over a 1 meter distance and is intended for short-reach connections between rack-mounted devices, including switches, routers and storage systems that accept QSFP-to-QSFP direct attach connections.

Advantages

The cable offers a compact, factory-terminated QSFP male-to-male connection that simplifies rack-to-rack or intra-rack linking while maintaining low latency and low power consumption. Constructed to MSA-compliant specifications, it is suitable for electrical twinax direct attach applications and supports Ethernet, FCoE and InfiniBand protocols at up to 40 Gbit/s over the specified distance. The passive design reduces potential failure points and lowers operational power compared with active optical modules.

Suitable for

• Short-reach 40 Gb/s links between QSFP ports in the same rack or adjacent racks
• High-performance computing (HPC) clusters using InfiniBand or 40G Ethernet
• Switch-to-switch, switch-to-router or switch-to-storage connections supporting QSFP
• Data center top-of-rack and middle-of-row patching for 40G interconnects

Key specifications

• Connector type: QSFP male to QSFP male
• Cable length: 1 metre
• Supported data rate: up to 40 Gbit/s
• Application types: Ethernet, FCoE, Fibre Channel, InfiniBand (protocol dependent)
• Cable type: passive direct attach twinax (40GBase-CR4 electrical twinax characteristics)
• Wire gauge: 30 AWG (as used in passive twinax construction)
• Compliance: MSA-compatible mechanical and electrical interface

How to use

Install the cable by inserting each QSFP male connector into the corresponding QSFP port until it clicks into place, ensuring both ends are seated firmly. Use the cable for direct electrical connections between devices configured to accept passive QSFP direct attach twinax cables and supporting the selected protocol at 40 Gbit/s. Avoid excessive bending near the connector heads and route the cable to prevent kinks, sharp bends or crush points that could degrade performance.

Recommendations

Verify that both endpoints explicitly support passive QSFP twinax direct attach cables and the 40GBase-CR4 electrical specification before deployment. For reliable operation maintain slack to avoid tight bends and keep the operating environment within the equipment manufacturer's temperature and humidity limits. For inventory control and compatibility checks, test one sample in your target hardware platform prior to large-scale rollout.
