AOC CBO QSFP-H40G-AOC20M-AL Active Optical Cable QSFP+ to QSFP+ 40Gb/s, 20 m

The AOC CBO QSFP-H40G-AOC20M-AL Active Optical Cable QSFP+ to QSFP+ 40Gb/s, 20 m is a factory-terminated optical link for high-speed connections between compatible QSFP+ ports. This 20‑metre cable integrates optical transceivers into the cable assembly to deliver a 40 Gb/s full-duplex connection without separate pluggable modules. It is intended for short- to medium-reach interconnects in data center racks and network equipment where a reliable, low-latency optical link is required.

Advantages

The integrated design reduces the number of discrete transceivers and simplifies deployment while maintaining signal integrity over a 20 m distance. Low power consumption relative to separate transceiver plus copper cabling options helps limit heat generation in densely packed equipment. The cable provides predictable optical performance with minimal configuration, reducing installation time and operational complexity.

Suitable for

• Server-to-switch connections inside data center racks
• Switch-to-switch uplinks across adjacent racks or within a single row
• High-bandwidth fabric connections in networked storage or compute clusters

Key specifications

• Connector type: QSFP+ to QSFP+
• Data rate: 40 Gb/s full duplex
• Length: 20 metres
• Cable type: Active optical cable (AOC) with integrated optical transceivers
• Typical application: Short- to medium-reach data centre interconnects
• Installation: Hot-pluggable between compatible QSFP+ ports

How to use

Ensure both devices have compatible QSFP+ ports that support 40 Gb/s AOC connections. Power on equipment before insertion if recommended by the device manufacturer. Align each QSFP+ connector with the port and insert the cable until it seats firmly; engage any latch mechanism present on the port. No additional transceiver configuration is normally required, but verify link status through the host device management interface and review port speed and health indicators. To remove the cable, release the latch and extract straight out to avoid damaging the connector or port.

Recommendations

Install the cable in a manner that avoids sharp bends and excessive tension; maintain the manufacturer's recommended bend radius for optical fibre. Use the cable indoors in controlled data centre environments and avoid exposure to liquids, extreme temperatures or mechanical stress. Verify firmware and driver compatibility on connected devices when troubleshooting link negotiation issues.
