BlueOptics CBL-QSFP-40GE-3M-F10-BO InfiniBand fibre optic cable 3m Male/Male

The BlueOptics CBL-QSFP-40GE-3M-F10-BO InfiniBand fibre optic cable is a 3-meter active optical cable with QSFP connectors on both ends, designed for high-speed short-range connections. It implements 40GBASE-SR4-compatible multi-mode optical transmission and integrates transceivers at each end to transmit and receive optical signals. The cable is intended for data centre and networking environments where reliable 40 Gbps links are required between switches, routers and servers.

Advantages

This BlueOptics active optical cable delivers 40 Gbps aggregate bandwidth over a 3 m multi-mode fibre link while following QSFP form-factor connectivity. The integrated transmitters and receivers reduce the need for separate SFP or transceiver modules and simplify installation. Compatibility with hardware platforms that support the original Force10 40GBASE-SR4 AOC enables straightforward replacement or expansion of existing short-reach 40G links. The compact, cable-integrated design helps maintain neat cable routing in racks and reduces electrical interference compared with copper alternatives.

Key specifications

How to use

Inspect the QSFP connectors and port guides for any debris before installation. Align the QSFP connector keyed tab with the port slot and insert the cable until it seats firmly; ensure both ends are fully engaged. For removal, depress the latch or release mechanism on the QSFP connector and extract the cable straight out to avoid damaging the port. Use the cable for short-range 40G links only and ensure connected devices are configured to the appropriate 40G protocol and lane mapping where required.

Recommendations

Install the cable in rack and patch environments that provide strain relief and avoid sharp bends; maintain bend radii recommended for multi-mode AOC assemblies. Keep the integrated QSFP connectors free of dust and store unused ends with protective caps. Verify compatibility with the host hardware platform’s QSFP specifications and firmware recommendations before deployment.
