AOC CBO OC40-QSFP-AOC-5M-C active optical cable, QSFP to QSFP, 5 m length

The AOC CBO OC40-QSFP-AOC-5M-C active optical cable is a 5 metre QSFP-to-QSFP interconnect engineered for short-reach 40G connections between high-speed networking devices. It delivers a plug-and-play fiber link that replaces bulky copper cabling while minimising electromagnetic interference. The cable is intended for use in data centre and enterprise environments where reliable, low-latency 40 Gigabit connectivity is required between switches, routers and servers.

Advantages

This active optical cable offers a compact, lightweight alternative to direct attach copper, reducing rack clutter and improving airflow. Its optical construction eliminates susceptibility to electromagnetic interference and crosstalk common with copper solutions. The plug-and-play QSFP-to-QSFP design simplifies installation and reduces configuration time while providing consistent 40G performance for short-reach links.

Suitable for

• High-density switch-to-switch uplinks in data centres
• Server-to-switch connections requiring 40G bandwidth
• Router interconnects and aggregation links within enterprise networks

Key specifications

• Connector type: QSFP to QSFP
• Effective link speed: 40 Gigabit
• Length: 5 metres
• Cable type: active optical cable (AOC)
• Application: short-reach multimode-style fibre interconnect for rack and chassis environments

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on network devices until the latch engages. No additional transceivers or patch panels are required; the link should be recognised automatically by devices that support QSFP-based 40G ports. Ensure ports are compatible with active optical cable connections and that firmware or driver support for QSFP modules is present where applicable. Route the cable to avoid sharp bends and secure it to maintain proper airflow and cable management within racks.

Recommendations

For reliable operation, verify device compatibility with QSFP AOC links and keep the cable within its specified 5 m length. Avoid tight radius bends and exposure to mechanical stress; store and handle the cable following standard fibre-optic practices. Use in controlled data centre or server room environments to maintain optimal signal integrity.
