The BlueOptics QSFP-40G-D-AOC-20M-CM-BO InfiniBand fibre optic cable is a 20-metre active optical cable with QSFP connectors on both ends, engineered for high-speed, low-latency interconnects in data centres and HPC environments. It supports 40 Gigabit data rates over a single QSFP interface and provides a compact, plug-and-play solution for short to medium reach connections between switches, routers and servers. The cable’s active optical design reduces electrical-to-optical conversion losses and simplifies cabling where high density and signal integrity are required.

Advantages

This QSFP to QSFP active optical cable delivers stable 40 Gbps throughput with reduced electromagnetic interference and improved thermal characteristics compared with copper alternatives. Its 20 m length enables flexible rack-to-rack or row-to-row connectivity while keeping signal quality consistent. The integrated QSFP connectors ensure straightforward installation and hot-pluggable operation, and the optical medium lowers attenuation over the specified reach, supporting reliable performance in demanding networking scenarios.

Key specifications

How to use

Inspect both QSFP connectors and port locations before installation to ensure correct orientation and seat the connectors gently into QSFP ports until they latch. Route the 20 m cable to avoid tight bends and mechanical strain; maintain the manufacturer’s recommended bend radius for optical assemblies. The cable is hot-pluggable—connect or disconnect with system power as permitted by your equipment’s guidelines—and should be tested after installation to verify link status, negotiated speed and error rates using standard diagnostics or management tools.

Recommendations

For optimal performance, use the cable within typical data centre environmental conditions, avoid sharp bends or kinks, and maintain secure routing to prevent physical stress. Verify QSFP port firmware and driver compatibility on connected devices and perform link tests after installing to confirm 40 Gbps operation and low error counts.
