## Summary description

The BlueOptics ET7402-AOC-20M-BO is a 20-meter InfiniBand fibre optic cable featuring QSFP28 male connectors on both ends. It is designed for high-speed data transmission in data centers and networking environments, ensuring reliable performance and minimal latency. Ideal for connecting switches, servers, and storage devices.

## Long description

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.
Suitable for
 Top-of-rack and end-of-row switch connections
 Server-to-switch high-speed links
 Storage area network (SAN) interconnects
 Short-reach InfiniBand and Ethernet 100G interconnects within data centres
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Length: 20 metres
 Cable type: Active Optical Cable (AOC) with multimode fibre
 Supported protocols: 100G Ethernet (100GBASE-SR4), InfiniBand and Fibre Channel over Ethernet capable
 Transmission: Integrated optical transmitter and receiver on each end for short-reach 100G links
 Typical use environment: Data centre rack and row-level interconnects
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.
Usage 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.
