Active Optical Cable CBO AOC-QSFP-40G-5M 40Gbps QSFP+ to QSFP+ 5 m

The Active Optical Cable CBO AOC-QSFP-40G-5M 40Gbps QSFP+ to QSFP+ 5 m is a 5‑metre duplex optical link with QSFP+ connectors designed for short‑reach, high‑speed interconnects. It carries up to 40 Gbps aggregate bandwidth between QSFP+ ports in switches, servers and storage systems. The cable integrates transceivers and a fiber optical medium into a single assembly to reduce signal attenuation and simplify rack cabling in data centres and server rooms.

Advantages

This Active Optical Cable offers low latency and energy-efficient operation compared with equivalent copper direct-attach solutions, while providing greater reach and immunity to electromagnetic interference. The integrated QSFP+ connectors support hot-pluggable installation and reduce the number of individual components required. The 5 m length is suitable for connecting devices within the same rack or across adjacent racks without intermediate patch panels.

Suitable for

• 40 Gbps QSFP+ interconnects between network switches
• Server-to-switch uplinks in data centres and server rooms
• Storage array connections requiring high throughput
• Short-reach links where reduced cabling complexity and EMI immunity are needed

Key specifications

• Connector type: QSFP+ to QSFP+
• Aggregate data rate: 40 Gbps
• Length: 5 metres
• Cable type: Active optical cable (integrated transceivers)
• Typical applications: data centre, server room, rack interconnects
• Performance: low latency, immunity to electromagnetic interference

How to use

Ensure compatible QSFP+ ports on both devices, power on the connected equipment and insert each QSFP+ connector into the corresponding port until it latches. The cable is hot‑pluggable and requires no separate power source. Verify link status on the host devices and configure port settings according to the equipment vendor’s guidelines for 40 Gbps operation. For best performance, avoid tight bends and maintain the manufacturer’s minimum bend radius.

Recommendations

Route the cable within rack management accessories or designated cable trays to prevent mechanical stress. Keep the cable away from sharp edges and sources of excessive heat. For reliable operation in multi‑vendor environments, confirm QSFP+ interoperability and firmware compatibility with switch and server vendors before deployment.
