BlueOptics CBL-QSFP+AOC-50M-BO InfiniBand/fibre optic cable 50m Male/Male

The BlueOptics CBL-QSFP+AOC-50M-BO InfiniBand/fibre optic cable 50m Male/Male is a 50-metre active optical cable (AOC) with QSFP-to-QSFP male connectors designed for high-speed links in data centres and high-performance computing environments. It uses multimode fibre with integrated transmitter and receiver modules at each end and follows common QSFP/MSA physical interfaces to support standard 40GBASE-SR4 and compatible InfiniBand or Ethernet applications over a 50 m length.

Advantages

This BlueOptics active optical cable provides consistent 40 Gbps-class throughput across a 50 m reach while avoiding the need for separate transceivers and patch cords. Its integrated optical transceivers reduce connector count and simplify installation in dense rack environments. The AOC design delivers electrical isolation and low latency for switch-to-switch, switch-to-server or server-to-storage interconnects where a compact, factory-terminated multimode fibre solution is preferred.

Suitable for

• 40GBASE-SR4 Ethernet links within data centres over 50 m distances
• InfiniBand high-speed links between switches and compute nodes
• Interconnects for storage arrays, routers and chassis systems that accept QSFP AOC modules
• Short-reach multi-lane fibre connections in HPC clusters and server racks

Key specifications

• Cable type: Active Optical Cable (AOC) with multimode fibre
• Connector type: QSFP male to QSFP male
• Length: 50 metres
• Supported link rate: up to 40 Gbps aggregate (compatible with 40GBASE-SR4/InfiniBand applications)
• Integrated transceivers: transmitter and receiver modules at both ends
• Typical use environment: data centre, server room, high-performance computing racks

How to use

Ensure both devices to be connected provide QSFP ports that support QSFP AOC modules and that firmware or vendor compatibility requirements are met. With equipment powered down or in maintenance mode as recommended by the device vendor, insert each QSFP male connector into the corresponding QSFP socket until it clicks or seats securely. Route the cable to avoid tight bends and mechanical strain, observing the manufacturer's minimum bend radius for multimode fibre. Power on the devices and verify link status through the network equipment management interface or port LEDs to confirm the 40 Gbps link is established.

Usage recommendations

Use the cable in channels and rack layouts that avoid excessive bending or compression, keep multimode patching distances within design limits, and verify device compatibility for QSFP AOC modules. For best performance, maintain clean connector interfaces and follow equipment vendor guidance on supported AOC modules and firmware versions.
