## Summary description

The BlueOptics Q28-AOC-7M-SP-BO is a 7m InfiniBand fibre optic cable designed for high-speed data transmission. It features QSFP28 connectors and OM3 fibre type with a core diameter of 50 µm, ensuring reliable performance for data centers and networking applications.

## Long description

The BlueOptics Q28-AOC-7M-SP-BO InfiniBand fibre optic cable is a 7 m active optical cable (AOC) with QSFP28 to QSFP28 connectors designed for high-speed short-range links in racks and between adjacent racks. Using OM3 multimode fibre with a 50 µm core diameter, this AOC supports 100GBASE-SR4 Ethernet and InfiniBand class data transmission. The cable integrates hot-pluggable transceiver modules with built-in electrical-to-optical and optical-to-electrical conversion, providing a lightweight, flexible alternative to direct-attach twinax solutions while complying with common SFF and IEEE mechanical specifications.
Advantages
The BlueOptics AOC delivers high bandwidth with reduced weight and improved flexibility compared with passive twinax cables. Its QSFP28 transceiver ends are manufactured to MSA standards and include integrated I/O converters for stable signal conversion over the full 7 m length. The OM3 multimode core and optimized optical design yield a small bend radius and consistent performance across short data-center distances. The cable sheath is LSZH (low smoke, zero halogen), improving safety in enclosed environments. Each AOC is factory tested for functionality and conforms to common industry regulatory requirements.
Suitable for
High-density server-to-switch connections within racks
Adjacent rack interconnects in data centers
100GBASE-SR4 Ethernet and InfiniBand high-speed links
Short-reach fiber connections requiring reduced weight and smaller bend radius
Key specifications
Cable type: Active Optical Cable (AOC)
Connector type: QSFP28 to QSFP28 (hot-pluggable)
Length: 7 m
Fibre type: OM3 multimode
Core diameter: 50 µm
Supported protocols: 100GBASE-SR4 Ethernet, InfiniBand-class high-speed transmission
Sheath: LSZH (low smoke zero halogen)
Design features: integrated electrical‑to‑optical and optical‑to‑electrical converters, small bend radius
How to use
Install the BlueOptics QSFP28-to-QSFP28 AOC by aligning the QSFP28 connectors with the transceiver ports on compatible switches, adapters or servers and inserting until the connector latches. No additional configuration is required for the cable itself; host devices will negotiate link parameters according to their interfaces. Handle the cable by the connector housings when plugging or unplugging, and avoid sharp bends or crush forces that could affect the fibre path. The LSZH sheath reduces hazardous emissions in case of fire but does not replace standard safety procedures in data centers.
Usage recommendations
Use this 7 m BlueOptics AOC for rack-level and adjacent-rack interconnects where 100 Gbps performance and reduced cable weight are required. Verify QSFP28 port compatibility on both devices and ensure proper routing to maintain the recommended bend radius. For long-term reliability, avoid repeated severe flexing near connector ends and perform standard pre-deployment link testing as part of installation procedures.
