BlueOptics CBL-0310-050-BO InfiniBand fibre optic cable 50 m QSFP

The BlueOptics CBL-0310-050-BO InfiniBand fibre optic cable 50 m QSFP is a 50-metre multimode active optical cable (AOC) with QSFP connectors on both ends. It is engineered for high-speed data transfer in data centre and networking environments, providing a QSFP-to-QSFP connection that follows MSA-compatible QSFP interconnect standards. The cable integrates optical transmitter and receiver assemblies at each end to carry multi-lane optical signals over 50 metres with minimal signal loss, supporting data rates used in 40GBASE-SR4 and similar 40 Gbit/s applications.

Advantages

The cable offers a factory-terminated, pluggable solution that eliminates field splicing and simplifies installation between QSFP ports. Its active optical design reduces electrical interference and heat generation compared with equivalent copper assemblies, while the multimode fibre path is optimized for short-reach, high-bandwidth links in racks and between adjacent network equipment. Compatibility with standard QSFP form-factor ports enables straightforward integration into switches, routers and storage systems that accept QSFP AOC modules.

Suitable for

• Short-reach interconnects in data centres and server racks
• High-bandwidth links between switches, routers and storage appliances
• 40GBASE-SR4 and other 40 Gbit/s multimode optical applications
• Environments requiring low electromagnetic interference and reduced heat

Key specifications

• Length: 50 metres
• Connector type: QSFP-to-QSFP
• Optical type: multimode active optical cable (AOC)
• Supported nominal data rate: up to 40 Gbit/s per link
• Designed for short-reach, intra-rack and adjacent-rack connections

How to use

Install the BlueOptics CBL-0310-050-BO by plugging the QSFP connectors into matching QSFP ports on network equipment while devices are powered according to the equipment manufacturer’s guidance. Ensure that ports support QSFP AOC modules and the intended 40 Gbit/s speed or protocol (for example 40GBASE-SR4). Route the cable to avoid sharp bends and mechanical strain; the active assemblies at each end should remain unobstructed for adequate airflow if installed in dense racks.

Usage recommendations

Verify compatibility with the host hardware and firmware before deployment. Use gentle cable bends respecting the manufacturer’s minimum bend radius, avoid excessive pulling force on connectors, and keep fibre ends and connector latches free of dust. For high-density deployments, label both ends and document link endpoints to simplify maintenance and troubleshooting.
