## Summary description

The BlueOptics Q28-AOC-25M-SP-BO is a 25-meter 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 efficient performance for data centers and networking applications.

## Long description

The BlueOptics Q28-AOC-25M-SP-BO InfiniBand fibre optic cable 25m QSFP28 is a 25-metre active optical cable (AOC) designed for short-reach 100G connections between devices within racks or between adjacent racks. It uses QSFP28 to QSFP28 connectors with integrated electrical-to-optical and optical-to-electrical conversion, OM3 multimode fibre with a 50 µm core and LSZH (low smoke zero halogen) flame-resistant sheathing. The cable conforms to common MSA, SFF and IEEE connector specifications and is intended for high-speed data centre and networking environments.
Advantages
The AOC design provides reduced weight and greater flexibility compared with direct-attach twinax cables while delivering the same 100GBASE-SR4 capability over short distances. Built-in transceiver electronics in the QSFP28 connectors convert signals between electrical and optical domains, enabling hot-pluggable operation. The OM3 multimode fibre and small bend radius support stable high-bandwidth performance. LSZH sheathing reduces hazardous emissions in case of fire. Each cable is factory new and tested for functionality and quality prior to dispatch.
Suitable for
 100G Ethernet links inside racks and between adjacent racks
 InfiniBand high-speed interconnects for servers and switches
 Data centre uplinks, spine-leaf topologies and switch-to-switch connections
 High-density networking environments requiring hot-pluggable interconnects
Key specifications
 Cable type: Active Optical Cable (AOC)
 Connector type: QSFP28 to QSFP28 (hot-pluggable)
 Length: 25 metres
 Fibre type: OM3 multimode fibre
 Core diameter: 50 µm
 Designed data rate: 100G (100GBASE-SR4 compatible)
 Sheathing: LSZH (low smoke, zero halogen), flame resistant
 Bend radius: reduced/smaller than typical DAC solutions (improved flexibility)
How to use
Install the cable by inserting each QSFP28 connector into compatible QSFP28 ports on switches, network interface cards or other compatible devices. Ensure ports are powered down or follow hot-plug guidance from your hardware vendor if connecting live. Route the cable to avoid excessive bending beyond the recommended bend radius and secure it to prevent strain on connectors. After connection, verify link status and speed on the connected devices and run any required diagnostics or link training procedures recommended by your equipment manufacturer.
Usage recommendations
Use this BlueOptics QSFP28 AOC for short-range 100G links where reduced weight, improved flexibility and hot-pluggability are required. Avoid tight bends and physical stress on the connector area, keep the LSZH sheath free of oil or abrasive contamination, and follow your hardware vendor’s guidance for hot-plug operation and link diagnostics to ensure reliable performance.
