## Summary description

The BlueOptics CBL-QSFP+AOC-20M-BO is a 20m InfiniBand fibre optic cable with QSFP connectors. Designed for high-speed data transmission, it features male/male connectors for easy connectivity. Ideal for data centers and networking applications, this cable ensures reliable performance and minimal signal loss.

## Long description

The BlueOptics CBL-QSFP+AOC-20M-BO InfiniBand fibre optic cable 20m Male/Male is a 20-metre active optical cable (AOC) with QSFP-to-QSFP connectors designed for high-speed interconnects. It implements a QSFP form factor with integrated transmitter and receiver modules on each end to transmit optical signals over multimode fibre, supporting up to 40 Gbit/s per lane aggregate throughput suitable for InfiniBand and 40GBASE-SR4 applications. The cable is intended for rack-to-rack and intra-rack connections in data centres and professional networking environments where low latency and reliable optical transmission are required.
Advantages
This cable provides a pre-terminated optical connection that reduces installation time and eliminates the need for separate transceivers and fibre patching for short to medium length links. Integrated transceivers on both ends ensure signal conditioning and compatibility with QSFP ports that follow common MSA specifications. The 20-metre length covers typical inter-rack distances while maintaining low insertion loss and consistent signal quality for high-bandwidth applications.
Suitable for
High-speed server-to-switch and switch-to-switch connections in data centres
InfiniBand fabric links and 40G Ethernet (40GBASE-SR4) interconnects
Storage area network (SAN) uplinks and high-throughput storage systems
Short- to medium-distance optical connections within racks and between adjacent racks
Key specifications
Connector type: QSFP to QSFP, male-to-male
Cable type: Active Optical Cable (AOC) with integrated transmitter and receiver modules
Supported protocols: InfiniBand and 40G Ethernet (40GBASE-SR4), Fibre Channel over Ethernet compatible
Maximum aggregate data rate: up to 40 Gbit/s for supported protocol configurations
Fibre type: multimode fibre suitable for SR4 short-range transmission
Length: 20 metres
Form factor: QSFP MSA-compliant interface
How to use
Connect the QSFP connector on one end of the cable to the corresponding QSFP port on your switch, router or host adapter, and plug the other QSFP connector into the remote QSFP port. Ensure that both ports support the same protocol and link speed (for example, 40GBASE-SR4 or compatible InfiniBand mode). Verify link status through your device management interface and check for proper negotiation of speed and lane configuration. No separate transceivers or fibre patch cords are required; the AOC provides a factory-terminated optical link.
Usage recommendations
Use this 20 m QSFP AOC for short- to medium-range high-bandwidth links in controlled data centre environments. Route the cable to avoid sharp bends and maintain minimum bend radius specified by the manufacturer to prevent optical attenuation. Confirm port compatibility and firmware settings on networking equipment before installation to ensure proper link operation. For environments requiring diagnostic monitoring or single-ended transceivers, consider active transceiver modules and structured patching instead of a direct AOC.
