The male-to-male configuration allows for easy installation and compatibility with various devices.

## Long description

The BlueOptics Q28-AOC-20M-AT-BO InfiniBand fibre optic cable 20m QSFP28 Male is a 20-metre active optical cable (AOC) with QSFP28 connectors on both ends, designed for 100G SR4-class high-speed links over multimode fibre. It provides a pre-terminated QSFP28-to-QSFP28 connection that integrates optical transceivers and multimode fibre in a single assembly to simplify installation in data centres and high-performance computing environments.
Advantages
This active optical cable supports 100G-class data transmission and is built to MSA-compliant QSFP28 form-factor specifications for interoperability with compatible hardware. The integrated transmitter and receiver modules at each end reduce the need for separate transceivers and patching, while multimode optical transmission reduces susceptibility to electromagnetic interference. The cable is tested for compatibility with platforms that support the corresponding original AOC standard and includes digital diagnostics monitoring for real-time link parameters where supported by host hardware.
Suitable for
 High-performance computing (HPC) cluster interconnects
 Data centre switch-to-switch or switch-to-server 100G links
 Storage system connectivity requiring short-reach 100G links
 Environments where pre-terminated, plug-and-play optical connections are preferred
Key specifications
 Cable type: Active Optical Cable (AOC) with integrated transceivers
 Length: 20 metres
 Connector type: QSFP28 to QSFP28 (male-to-male)
 Data rate: up to 100 Gbit/s (100GBASE-SR4 / InfiniBand-class equivalent)
 Fibre type: multimode fibre (designed for short-reach multimode applications)
 Digital diagnostics: DDM/DOM support for real-time monitoring if supported by host
 Standards: QSFP28 MSA-compliant mechanical and electrical interface
How to use
Install the BlueOptics Q28-AOC-20M-AT-BO by inserting the QSFP28 connectors into the QSFP28 ports of the devices to be linked, ensuring correct orientation and full seating. Use the cable for short-reach multimode 100G links between switches, servers, or storage systems. If the host devices support digital diagnostics, monitor link parameters such as voltage, laser bias, output/received power and temperature through the device management interface to assist with troubleshooting and maintenance.
Usage recommendations
Avoid sharp bends and excessive mechanical stress on the cable; maintain the manufacturer-recommended bend radius for multimode AOCs. Confirm that connected hardware supports QSFP28 AOC modules and the DDM/DOM features if monitoring is required. For deployments in racks and cable trays, secure the cable to prevent strain on connectors and maintain optimal optical performance.
