CBO AOC QSFP-H40G-AOC10M-AL 10m active optical cable for QSFP+ 40GbE links

The CBO AOC QSFP-H40G-AOC10M-AL 10m active optical cable is a 10-metre QSFP-compatible link designed for 40GbE high-speed connections. This pre-terminated AOC provides a direct optical interface for QSFP/QSFP+ ports, offering consistent low-latency transmission and immunity to electromagnetic interference. Its form factor enables compact, reliable rack-to-rack or switch-to-switch cabling in high-density environments such as data centres and aggregation layers.

Advantages

The active optical construction reduces signal degradation over the 10 m distance compared with equivalent copper cables and eliminates the need for transceiver modules in each end. The cable supports 40Gb Ethernet bandwidth with predictable performance, simplified cable management thanks to its thin, flexible design, and lower heat and power footprint at the connection points. Compatibility with standard QSFP/QSFP+ ports ensures easy deployment without special adaptor hardware.

Suitable for

• High-density data centre top-of-rack and spine-leaf interconnects
• Switch-to-switch aggregation and core links requiring 40GbE
• Server racks or storage arrays where low-latency optical links are needed
• Environments sensitive to electromagnetic interference where copper cabling is undesirable

Key specifications

• Connector type: QSFP/QSFP+ compatible optical interfaces
• Length: 10 metres (active optical cable)
• Supported data rate: 40 Gigabit Ethernet
• Transmission medium: multimode active optical link
• Latency: low, suitable for aggregation and fabric interconnects
• Form factor: pre-terminated thin, flexible cable for high-density racks

How to use

Install the AOC by inserting each QSFP connector into compatible QSFP or QSFP+ ports on your switches or equipment until the latch engages. No field termination or additional transceivers are required; the cable provides a ready-made optical connection. Verify link status on the connected devices and confirm the negotiated 40GbE speed in the switch or NIC management interface. Route the cable to minimise sharp bends and avoid crushing; follow device vendor guidelines for port usage and hot-plug operations.

Recommendations

For reliable operation, maintain bend radii larger than the manufacturer’s minimum and avoid stepping on or tightly clamping the cable. Use in patching aisles or between adjacent racks for optimal performance; verify compatibility with switch firmware and QSFP port specifications before deployment.
