## Summary description

The BlueOptics Q28-AOC-7M-PA-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 and reliability for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-7M-PA-BO InfiniBand fibre optic cable is a 7 m QSFP28 to QSFP28 Active Optical Cable (AOC) designed for high-speed short-reach interconnects in data centers and high-performance computing environments. Using OM3 multimode fibre with a 50 µm core diameter, this cable supports 100GBASE-SR4 Ethernet and InfiniBand connectivity while offering reduced weight and improved flexibility compared with direct-attach copper solutions. The QSFP28 connectors include integrated optical/electrical conversion components and conform to SFF/MSA and relevant IEEE specifications. The sheath is LSZH (low smoke, zero halogen) to reduce hazardous emissions in case of fire.
Advantages
Active Optical Cable technology provides electrical-to-optical conversion at the connector, enabling reliable 100 Gbps links over multimode OM3 fibre with lower insertion loss and a smaller bend radius than equivalent twinax solutions. The 7 m length is suited for connections inside racks or between adjacent racks while keeping cabling weight and bulk to a minimum. Built to industry specifications, the cable uses tested components and is factory-checked for functionality and compliance with widely accepted standards for safety and electromagnetic compatibility.
Suitable for
 High-density rack interconnects and adjacent-rack links in data centers
 100GBASE-SR4 Ethernet and InfiniBand high-speed connections
 Connections between QSFP28 ports on switches, routers, servers, and network adapters
 Environments requiring LSZH sheathing for reduced smoke and halogen emissions
Key specifications
 Cable type: Active Optical Cable (AOC)
 Connectors: QSFP28 to QSFP28
 Length: 7 meters
 Fibre type: OM3 multimode fibre
 Core diameter: 50 µm
 Supported protocol: 100GBASE-SR4 Ethernet and InfiniBand
 Sheath material: LSZH (low smoke, zero halogen)
 Bend performance: reduced bend radius compared with twinax
How to use
Ensure compatible QSFP28 ports on both devices before installation. With devices powered down or following hot-plug guidance from the equipment manufacturer, align and insert each QSFP28 connector into the corresponding port until it latches. The built-in optical/electrical converters allow immediate link establishment when both ends are seated and the host devices recognize the module. Follow your switch or host operating system instructions to verify link speed, status LEDs, and any required configuration for 100G operation.
Usage recommendations
Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s minimum bend radius. Use cable management within racks to prevent tension on the connectors. For safety and longevity, avoid exposure to liquids or excessive heat, and verify port compatibility and firmware settings on networking equipment to ensure optimal 100G performance.
