## Summary description

The BlueOptics Q28-AOC-7M-CI-BO is a 7m InfiniBand/fibre optic cable featuring OM3 fibre type and QSFP28 connectors. Ideal for high-speed data transfer in data centers and networking applications.

## Long description

The BlueOptics Q28-AOC-7M-CI-BO is a 7 m active optical cable (AOC) with QSFP28 connectors and OM3 multimode fiber designed for short-range, high-speed InfiniBand and 100GBASE-SR4 Ethernet links. The cable converts electrical signals to optical signals and back at the connector ends, enabling hot-pluggable QSFP28-to-QSFP28 connections between devices within a rack or between adjacent racks. The AOC construction yields reduced weight and greater flexibility compared with direct-attach twinax solutions while maintaining performance suitable for data center and high-performance computing environments.
Advantages
The BlueOptics AOC provides a lower bend radius and smaller cable diameter than comparable twinax cables, improving routing in dense rack environments. Its QSFP28 transceiver-style connectors follow MSA, SFF and IEEE specifications to ensure interoperability with compatible ports. The OM3 multimode fiber and integrated electrical-to-optical conversion support 100G data rates over the 7 m span. The cable uses LSZH (low smoke zero halogen) jacket material for reduced toxic emissions in case of fire and is manufactured and tested to industry standards for consistency and reliability.
Suitable for
Short-reach 100G Ethernet links (100GBASE-SR4) inside racks or between adjacent racks
InfiniBand high-bandwidth connections in server and HPC clusters
Interconnects for switches, routers and network appliances with QSFP28 ports
Data center cable management where reduced weight and tight bend routing are required
Key specifications
Cable type: Active Optical Cable (AOC) with integrated electrical/optical conversion
Connector type: QSFP28 to QSFP28, hot-pluggable
Length: 7 meters
Fiber type: OM3 multimode
Supported standard: 100GBASE-SR4 Ethernet and InfiniBand high-speed links
Jacket: LSZH (low smoke zero halogen), flame resistant
Bend radius: smaller than typical twinax solutions for improved routing (manufacturer design)
How to use
Install the BlueOptics Q28-AOC-7M-CI-BO by inserting each QSFP28 connector into the corresponding QSFP28 port until the connector latches. The cable is hot-pluggable; devices will enumerate the link according to their own port and firmware behavior. Ensure both ends are connected to compatible QSFP28 ports configured for 100G operation or the intended InfiniBand link. Avoid sharp bends and secure the cable to maintain the recommended bend radius and to prevent stress on the connectors. No separate transceiver modules or patch cords are required for operation because the optical conversion is integrated in the cable ends.
Usage recommendations
Handle the cable by the connector housings when plugging or unplugging and route it with gentle curves to preserve the OM3 fiber performance. Verify port compatibility and firmware support for QSFP28 AOC links in your equipment, and follow rack-cable management practices to avoid strain or interference. For safety and longevity, keep the LSZH jacket clean and avoid exposure to excessive heat or mechanical abrasion.
