Fibre optic InfiniBand cable BlueOptics B4QZ-BO QSFP56–QSFP56, 15 m, orange, male–male

BlueOptics B4QZ-BO is a 15 m fibre optic InfiniBand active optical cable with QSFP56 connectors on both ends (male–male). Designed for short- to medium-reach, high-bandwidth links in networking and high-performance computing environments, the cable features an orange jacket for easy identification and handling. It follows QSFP56 form-factor interfaces and supports multi-mode optical transmission suitable for 200GBASE-SR4 class applications when used with compatible QSFP56 ports on switches, adapters and servers.

Advantages

The cable provides a compact, low-latency connection between QSFP56 ports while integrating optical transceivers and receivers in the connector housings to enable high-speed optical transmission over 15 m. The orange outer jacket improves visibility in dense cabling environments. Male-to-male QSFP56 connectors ensure direct plug-and-play connection to QSFP56-compliant modules without additional adapters. The design targets reliable signal integrity and compatibility with equipment that accepts QSFP56 AOC solutions.

Key specifications

How to use

Ensure both devices have QSFP56 ports that support active optical cable connections and are powered off or in a maintenance state if recommended by the device manufacturer. Align the QSFP56 connectors with the port guides and insert until the latch engages. Verify link status using the host system or network equipment LEDs and management interfaces. To remove, release the connector latch and pull straight out without bending the cable sharply. Follow vendor guidelines for hot-plugging if supported.

Recommendations

Install and route the cable avoiding tight bends and excessive tensile stress; maintain minimum bend radius recommended for multi-mode AOC assemblies. Use the orange jacket for visual management in patching fields. Verify compatibility with the equipment vendor’s supported QSFP56 AOC list before deployment and test link performance after installation.
