InfiniBand/fibre optic cable BlueOptics 02310MUJ-BL 5 m QSFP Male/Male

The BlueOptics 02310MUJ-BL is a 5 m InfiniBand/fibre optic QSFP male-to-male cable designed for short-range, high-speed interconnects in racks and between adjacent racks. It supports 40GBase-CR4 electrical signaling over a direct attach twinax copper design with QSFP connectors and 30 AWG conductor specification. The cable is MSA-compliant and intended for use with hardware platforms that support 40G QSFP direct attach connections, providing reliable data transmission for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 40 Gbit/s on a 5 m link.

Advantages

This 5 m QSFP male-to-male cable delivers low latency and low power consumption characteristic of passive direct attach twinax solutions. MSA compliance ensures mechanical and electrical compatibility with major vendor ports that support 40GBase-CR4 QSFP direct attach cabling. The use of quality components and a straightforward passive design reduces failure points and contributes to long operational lifetime and high availability in rack environments.

Suitable for

• Short-range 40 Gbit/s connections between switches in the same rack or adjacent racks
• Server-to-switch or switch-to-storage links that accept QSFP direct attach twinax cables
• High-throughput Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 40G

Key specifications

• Cable type: passive direct attach twinax copper
• Connector type: QSFP male to QSFP male
• Length: 5 meters
• Supported data rate: up to 40 Gbit/s
• Conductor gauge: 30 AWG
• Standards: MSA-compliant for QSFP 40GBase-CR4 applications
• Typical use: short-distance rack and adjacent-rack interconnects

How to use

Ensure both endpoints support passive QSFP direct attach twinax cables and the 40GBase-CR4 signaling protocol. Power down or follow hot-plug guidance from your equipment vendor if required, align and insert each QSFP connector into the corresponding port until it latches. Verify link status in the host or switch management interface and confirm negotiated speed and protocol. Avoid sharp bends, excessive pulling force, and exposure to sources of electromagnetic interference during installation.

Recommendations

For reliable operation, use this cable for short, point-to-point connections inside racks or between immediately adjacent racks. Confirm vendor compatibility with passive 40G QSFP twinax cables and check port firmware or software settings if link negotiation fails. Store and route the cable without tight bends; maintain the manufacturer’s minimum bend radius and avoid mechanical stress on the QSFP connectors.
