## Summary description

The BlueOptics Q28-AOC-7M-QL-BO is a 7m InfiniBand fibre optic cable featuring QSFP28 connectors. It utilizes OM3 fibre optic type with a core diameter of 50 µm, ensuring high-speed data transmission for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-7M-QL-BO InfiniBand fibre optic cable is a 7 m active optical cable (AOC) with QSFP28 connectors designed for short-range, high-speed interconnects in data centres and high-performance computing environments. It uses OM3 multimode fibre with a 50 µm core diameter and supports 100GBASE-SR4 Ethernet-class transmissions. The cable features LSZH (low smoke zero halogen) flame-resistant sheathing, hot-pluggable QSFP28 ends with integrated electrical-to-optical and optical-to-electrical conversion, and compliance with SFF/MSA and IEEE connector specifications.
Advantages
This 7 m BlueOptics AOC offers lower weight and greater flexibility compared with direct attach twinax (DAC) solutions while maintaining high data rates and signal integrity for short-distance connections. The built-in transceiver modules reduce the need for separate external optics and simplify installation. The LSZH jacket reduces hazardous emissions in case of fire and the cable’s smaller bend radius and reduced diameter improve cable management inside racks and between adjacent racks. Each cable is factory new and tested for quality and functionality.
Suitable for
 High-density rack-to-rack connections in data centres
 Top-of-rack and end-of-row high-speed interconnects
 High-performance computing clusters and InfiniBand fabric links
 Short-reach 100GBASE-SR4 Ethernet links
Key specifications
 Length: 7 metres
 Connector type: QSFP28 to QSFP28 (hot-pluggable)
 Fibre type: OM3 multimode, 50 µm core
 Supported standard: 100GBASE-SR4 / InfiniBand-compatible high-speed links
 Cable jacket: LSZH (low smoke, zero halogen), flame resistant
 Bend radius: reduced design for improved routing in racks
 Form factor/compliance: SFF/MSA and relevant IEEE connector specifications
How to use
Connect the QSFP28 connector on one end of the BlueOptics Q28-AOC-7M-QL-BO to a QSFP28 port on a compatible switch, server or network adapter, and the other QSFP28 connector to the corresponding port on the remote device. The cable is hot-pluggable; ensure devices are powered and configured to recognise QSFP28 AOC modules. No separate transceiver modules or additional fibre patching are required, as the electrical-optical conversion is integrated into the cable ends. Confirm link speed and lane mapping settings on connected equipment to match 100GBASE-SR4 or InfiniBand link requirements.
Usage recommendations
Route the cable with gentle bends and avoid tight loops to preserve the smaller bend radius and ensure long-term signal integrity. Use proper cable management within racks to prevent strain on QSFP28 connectors and maintain airflow. Verify compatibility with host equipment firmware and link settings prior to deployment and inspect connectors for contamination before insertion.
