## Summary description

The BlueOptics Q28-AOC-7M-BC-BO is a 7m InfiniBand fibre optic cable designed for high-speed data transfer. It features OM3 fibre type and QSFP28 connectors on both ends, ensuring optimal performance for data centers and networking applications. With a core diameter of 50 µm, this cable is ideal for short-range connections in high-bandwidth environments.

## Long description

The BlueOptics Q28-AOC-7M-BC-BO InfiniBand fibre optic cable 7m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends. Designed for short-range, high-bandwidth interconnects in data centers and networking racks, it uses OM3 multimode fibre with a 50 µm core diameter to support 100GBASE-SR4 and similar high-speed links. The cable integrates optical transceiver modules at each end to convert electrical signals to optical and back, offering a lightweight, flexible alternative to direct attach twinax (DAC) for rack-to-rack or intra-rack connections.
Advantages
This BlueOptics AOC provides reduced weight and improved flexibility compared with DAC solutions while maintaining hot-pluggable QSFP28 connectivity. The integrated I/O and O/E conversion modules support consistent high-speed transmission and minimize signal loss across the 7 meter span. The OM3 multimode fibre and optimized bend radius deliver reliable performance for short-reach, high-bandwidth applications. The cable uses LSZH (low smoke zero halogen) flame-retardant sheathing for enhanced safety in enclosed spaces.
Suitable for
100GBASE-SR4 interconnects within or between adjacent server racks
High-density switch-to-switch links in data centers
InfiniBand short-reach connections for HPC clusters
Upgrades from DAC to optical links for improved flexibility and reduced weight
Key specifications
Connector type: QSFP28 to QSFP28 (hot-pluggable)
Fibre type: OM3 multimode
Core diameter: 50 µm
Length: 7 meters
Application: 100G short-reach optical transmission (e.g., 100GBASE-SR4)
Sheathing: LSZH (low smoke zero halogen), flame resistant
Built-in optical transceivers with electrical-to-optical and optical-to-electrical conversion
Compliant with SFF/MSA and relevant IEEE specifications
How to use
Ensure both endpoints support QSFP28 interfaces and are powered off or follow hot-plug guidelines from the equipment vendor. Remove protective caps from the QSFP28 connectors, align the connector latch with the port, and insert the module until it seats and latches securely. For removal, release the latch mechanism and pull the cable straight out. Avoid tight bends near the connector and maintain the cable bend radius recommended for multimode fibre to prevent signal degradation. Perform link validation according to your switch or host adapter diagnostics after installation.
Usage recommendations
Store and route the cable to avoid sharp bends and mechanical strain; maintain ambient operating conditions specified by your networking equipment. Choose OM3-compatible transceivers and ports for optimal performance and ensure periodic inspection of connector endfaces for contamination; clean connectors with appropriate fibre-optic cleaning tools if required.
