Active Optical Cable CBO AOC-QSFP-40G-30M 40Gbps QSFP+ to QSFP+ 30 m

Active Optical Cable CBO AOC-QSFP-40G-30M 40Gbps QSFP+ to QSFP+ 30 m is a multimode fibre assembly designed for short-reach 40 Gigabit links between QSFP+ ports. The cable integrates QSFP+ connectors with an embedded optical transceiver and a 30-metre multimode optical fibre, delivering 40Gbps aggregate bandwidth with low latency and reduced electrical power consumption compared with equivalent copper direct-attach cables. Its plug-and-play form factor allows fast deployment in data centre top-of-rack, leaf-spine switch fabrics and storage networking environments.

Advantages

The Active Optical Cable offers high-speed 40Gbps throughput with consistent signal integrity over a 30-metre multimode link. By using optical transmission it reduces weight and electromagnetic interference, and typically draws less power than copper alternatives for comparable reach. The integrated QSFP+ connector and hot-pluggable design simplify installation and replacement without additional transceiver modules. The cable is suitable for dense rack deployments where reduced cable bulk and improved airflow are important.

Suitable for

• Server-to-switch and switch-to-switch short-reach 40Gbps interconnects
• Top-of-rack and leaf-spine data centre network fabrics
• High-performance storage area network (SAN) links
• High-density patching environments requiring compact, low-weight cabling

Key specifications

• Connector type: QSFP+ to QSFP+
• Data rate: 40 Gbps aggregate
• Link length: 30 metres over multimode fibre
• Optical medium: multimode fibre (pre-assembled)
• Form factor: active optical cable with integrated transceivers
• Latency: low, suitable for switch and server interconnects

How to use

Install the AOC by inserting each QSFP+ connector into the corresponding QSFP+ port on networking equipment or servers until the latch engages. Ensure both ends are seated and that ports are powered and configured for 40Gbps operation if required by the host. The cable is hot-pluggable; connect or disconnect while systems are powered according to the equipment vendor’s guidelines. No separate transceivers or fibre termination are required since the optical transceivers are integrated into the cable assemblies.

Recommendations

Verify compatibility of the QSFP+ ports with active optical cables and confirm system firmware or driver support for 40Gbps links. Route the cable to avoid tight bends and mechanical strain; maintain the manufacturer’s minimum bend radius and protect fibre ends from contamination when unplugged. For best thermal and airflow performance in dense racks, prefer routing paths that minimize cable bundle thickness.
