BlueOptics QSFP-AOC-20M-PS-BO InfiniBand fibre optic cable 20m Male/Male

The BlueOptics QSFP-AOC-20M-PS-BO InfiniBand fibre optic cable is a 20-meter active optical cable with QSFP-to-QSFP male connectors designed for high-speed data transmission in data centres and networking environments. It implements active optical transceivers at both ends to send and receive optical signals over multi-mode fiber and is intended for 40G applications such as 40GBASE-SR4, supporting Ethernet and protocol-agnostic high-speed links across a 20 m channel.

Advantages

This BlueOptics AOC provides a pre-assembled QSFP to QSFP connection that removes the need for field termination or patching, reducing insertion loss and exposure to contamination. The integrated transmitter and receiver modules at each cable end enable low-latency, full-duplex optical transmission suitable for high-bandwidth environments. The cable is manufactured to MSA-compliant mechanical and electrical specifications and is tested for compatibility and reliable operation in systems that support QSFP AOC modules.

Suitable for

• High-speed 40G links between switches, routers and storage systems
• InfiniBand and Ethernet fabric connections in data centres
• Short-reach multi-mode fiber runs up to 20 meters within racks and between adjacent racks

Key specifications

• Cable type: Active Optical Cable (AOC) with QSFP male connectors on both ends
• Length: 20 meters
• Supported data rates: up to 40 Gbit/s per link (40GBASE-SR4 compatible)
• Fiber type: multi-mode optical transmission via integrated transceivers
• Interface: QSFP to QSFP, full-duplex optical laser transmission
• Diagnostic support: Digital Diagnostics Monitoring (DDM/DOM) compliant with SFF-8472 (when supported by host hardware)
• Compliance: manufactured to MSA mechanical and electrical specifications

How to use

Install the BlueOptics QSFP-AOC-20M-PS-BO by inserting the QSFP male plug into each QSFP-capable port until the module latches. Ensure the host devices support QSFP AOC modules and that their firmware allows third-party compatible AOCs if required. If DDM/DOM monitoring is needed, verify that the host hardware exposes diagnostic data. No field termination or connector cleaning is required for the pre-assembled cable; handle connectors by the module body and avoid touching the optical interfaces.

Recommendations

Use this 20 m QSFP AOC for short-reach multi-mode interconnects inside racks or between adjacent racks. Route the cable to avoid tight bends and mechanical stress; follow the minimum bend radius for QSFP AOC assemblies and avoid continuous flexing. Confirm host compatibility for DDM/DOM features before deployment and test the link after installation to verify expected 40G operation.
