Active Optical Cable CBO AOC-QSFP-40G-20M 40G 20m QSFP+ to QSFP+

BlueOptics Active Optical Cable CBO AOC-QSFP-40G-20M is a 20-metre QSFP+ to QSFP+ link engineered for 40G data rates. This pre-terminated active optical cable integrates QSFP+ connectors at both ends and a fixed optical assembly to enable high-speed connections between compatible QSFP+ ports in switches, servers and storage systems. The design reduces electrical interference and removes the need for transceiver modules, offering a compact, low-latency interconnect suitable for dense rack and data centre topologies.

Advantages

The Active Optical Cable delivers 40G performance over a 20 m reach while maintaining low power consumption and minimal signal attenuation. Its integrated optical transceivers eliminate separate module installation, simplifying rack cabling and reducing points of failure. The optical medium provides immunity to electromagnetic interference and supports long, reliable links between equipment in adjacent racks or within the same row.

Suitable for

• High-throughput links between QSFP+ ports on switches and routers
• Server-to-switch and storage-to-switch interconnects in data centres
• Top-of-rack or end-of-row aggregated connections
• Environments requiring low-latency, interference-free cabling

Key specifications

• Connector type: QSFP+ to QSFP+
• Data rate: 40 Gbit/s
• Cable length: 20 metres (fixed)
• Cable type: Active optical assembly
• Transmission medium: Optical fiber
• Typical usage: Short-reach data centre interconnect

How to use

Install the cable by inserting each QSFP+ connector into the corresponding QSFP+ port until the latch engages. Ensure both devices support 40G QSFP+ active optical links and that ports are enabled and correctly configured through the host equipment. Route the cable to avoid sharp bends and mechanical stress; secure it with cable ties or management panels as required. No separate transceiver modules or soldering are needed because the optical transceivers are integrated into the cable ends.

Recommendations

Use in temperature-controlled data centre environments and avoid repeated insertion/removal cycles to preserve connector life. Follow vendor port configuration guidelines when connecting heterogeneous equipment and verify link status through device LEDs or management interfaces after installation.
