BlueOptics EX-QSFP-8LC-AOC20M-BO InfiniBand fibre optic cable 20 m

The BlueOptics EX-QSFP-8LC-AOC20M-BO InfiniBand fibre optic cable 20 m is a 20-metre active optical cable (AOC) with QSFP male connectors on both ends. Designed for high-speed data transmission, this multi-mode fibre AOC integrates transmitter and receiver electronics in each connector to support short-range 40 Gbit/s links over multimode fibre. It is compatible with systems that accept QSFP-to-QSFP AOC modules and is intended for use in data centres, server rooms and high-performance computing networks where reliable 40G interconnects are required.

Advantages

This active optical cable offers low-latency 40G connectivity with integrated optical transceivers for simplified installation and reduced component count compared with discrete transceivers and patch cords. The fixed 20 m length removes the need for intermediate patching, while QSFP male interfaces ensure plug-and-play compatibility with equipment that supports QSFP AOC modules. As a multimode AOC, it provides stable short-range optical performance and electrical isolation between connected devices.

Suitable for

• Interconnecting switches and routers in racks and top-of-rack deployments
• Server-to-switch and server-to-storage links in data centres
• High-performance computing clusters and InfiniBand fabrics requiring 40G links
• Short-reach 40G applications in enterprise and colocation environments

Key specifications

• Length: 20 metres
• Connector type: QSFP male to QSFP male
• Transmission type: Active Optical Cable (AOC) with integrated transmitter and receiver
• Supported data rate: up to 40 Gbit/s
• Fibre type: multimode fibre (designed for short-range multimode applications)
• Compatibility: QSFP-to-QSFP equipment supporting 40G AOC modules

How to use

Install the BlueOptics AOC by aligning and inserting the QSFP connectors into QSFP ports on the devices to be linked. Ensure both devices are powered and support 40G QSFP AOC modules. The cable’s integrated transceivers will be recognised by compatible hardware and negotiate the appropriate link settings automatically. Avoid excessive bending of the cable near the connector ends and route the cable in rack channels or cable trays to prevent mechanical strain.

Usage recommendations

For reliable operation, use this 20 m BlueOptics AOC in short-reach multimode environments and verify device compatibility with QSFP AOC modules. Maintain manufacturer-recommended bend radii, keep connectors clean and protected when not in use, and avoid running the cable alongside high-voltage power lines to reduce interference risks.
