BlueOptics ET7402-AOC-20M-BO InfiniBand fibre optic cable QSFP28 20m Male/Male

The BlueOptics ET7402-AOC-20M-BO InfiniBand fibre optic cable QSFP28 20m Male/Male is a 20-metre active optical cable (AOC) with QSFP28 male connectors on both ends, designed for high-speed links in data centre and enterprise networking environments. The cable integrates optical transmitters and receivers and uses multimode fibre to support short-reach 100G data transmission with low latency and stable signal integrity across a 20 m channel.

Advantages

This QSFP28 AOC offers native compatibility with QSFP28 ports and follows MSA-compliant electrical and optical interfaces for predictable performance. By using integrated transceivers, it reduces the need for separate optical transceivers and simplifies installation while maintaining 100G capable throughput. The multimode optical path provides consistent latency and signal quality for switch-to-switch, server-to-switch, and storage interconnects inside racks and across adjacent racks.

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 male connector into the corresponding QSFP28 port on switches, servers, or storage devices until the latch engages. Ensure that both ends are seated correctly and the connected devices are powered and configured for 100G operation or the appropriate InfiniBand protocol. No separate SFP/QSFP transceivers are required because the optical transceivers are integrated into the cable ends. Route the cable to avoid sharp bends and maintain minimum bend radius recommended for multimode fibre to preserve optical performance.

Recommendations

Use this 20 m QSFP28 AOC for reliable short-reach 100G links inside racks and between adjacent racks. Verify device compatibility with QSFP28 ports and confirm firmware or port configuration supports the targeted protocol (100G Ethernet or InfiniBand). Avoid tight bends and mechanical stress, and handle the connectors by the housing to prevent contamination of optical interfaces.
