BlueOptics EX-QSFP-8LC-AOC50M-BO InfiniBand fibre optic cable 50 m QSFP Male/Male

The BlueOptics EX-QSFP-8LC-AOC50M-BO InfiniBand fibre optic cable is a 50 m active optical cable (AOC) with QSFP Male to QSFP Male connectors designed for high-speed data transmission in data centers and networking environments. The cable implements QSFP-compatible connections according to MSA standards and integrates transmitters and receivers on each end to transport optical signals over multimode fibre. It supports 40G-class links up to 50 metres and is intended for use where reliable, low-latency connectivity is required.

Advantages

This active optical cable combines integrated optical transceivers with a fixed QSFP-to-QSFP form factor for a consistent physical interface and reduced configuration complexity. By using multimode fibre and built-in transmitter/receiver modules it provides stable signal integrity across the full 50 m length and is suitable for short-reach 40G links in racks and adjacent rows. The cable’s construction reduces electromagnetic interference and heat generation compared with equivalent copper assemblies, while offering a compact, light-weight solution for high-density installations.

Suitable for

• 40G high-speed connections between switches and routers within data centres
• Interconnects for storage systems and server clusters requiring InfiniBand or 40G Ethernet
• Short-reach backbone links in rack-to-rack or row-to-row deployments up to 50 m

Key specifications

• Cable type: Active Optical Cable (AOC) with multimode fibre
• Connector type: QSFP Male to QSFP Male
• Supported rate: up to 40 Gbit/s per link
• Maximum length: 50 metres
• Form factor: QSFP-compatible, MSA-compliant interface

How to use

Install the BlueOptics EX-QSFP-8LC-AOC50M-BO by aligning each QSFP connector with the corresponding QSFP port on active equipment and inserting until the latch engages. No separate transceivers or fibre termination is needed because the optical transceivers are integrated into the cable ends. Ensure both ends are connected to compatible QSFP ports that support 40G or InfiniBand signalling and verify link status using the host device management interface. Avoid bending the cable below the manufacturer’s minimum bend radius and keep connectors free of dust before insertion.

Usage recommendations

Use this AOC for short-reach 40G or InfiniBand interconnects within the supported 50 m range. Confirm hardware compatibility with the target switches, routers or storage platforms and follow standard data-centre cable management practices to prevent excessive bending or strain. For installations requiring longer distances or single-mode operation, consider appropriate optical transceivers and single-mode fibre alternatives.
