## Summary description

The BlueOptics Q28-AOC-25M-CO-BO is a 25m 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 supports high bandwidth and low latency connections, making it ideal for demanding environments.

## Long description

The BlueOptics Q28-AOC-25M-CO-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends, designed for short-range 100G high-speed links inside and between racks. Featuring OM3 multimode fibre with a 50 µm core diameter and a 25 metre length, this cable converts electrical signals to optical and back via integrated transceiver modules in the QSFP28 housings. The cable is intended for low-latency, high-bandwidth applications and includes an LSZH (low smoke zero halogen) flame‑resistant jacket for improved safety in data-centre environments.
Advantages
The active optical design delivers 100GBASE-SR4-compatible performance with reduced weight and greater flexibility compared with direct-attach twinax solutions. Integrated I/O and O/E converters in the QSFP28 connectors provide hot-pluggable operation and reliable signal conversion over the full 25 m length. The OM3 multimode fibre and industry-standard QSFP28 MSA-compliant connectors enable high bandwidth, small bend radius and consistent interoperability with compatible hardware. The LSZH sheath reduces harmful emissions in case of fire while meeting relevant industry safety standards.
Suitable for
 Server-to-switch and switch-to-switch connections within racks or between adjacent racks
 100GBASE-SR4 Ethernet and InfiniBand short-reach high-speed links
 Data centre cabling where reduced weight, flexibility and safety (LSZH) are required
 Environments requiring MSA-compliant QSFP28 interfaces and plug-and-play operation
Key specifications
 Length: 25 metres
 Connector type: QSFP28 to QSFP28 (hot-pluggable)
 Fibre type: OM3 multimode
 Core diameter: 50 µm
 Supported link standard: 100G (100GBASE-SR4) / InfiniBand short-reach
 Sheathing: LSZH (low smoke zero halogen), flame resistant
 Bend radius: small bend radius suitable for dense rack cabling (AOC design)
How to use
Ensure both devices support QSFP28 interfaces and are configured for the intended 100G or InfiniBand link. Insert each QSFP28 connector into the corresponding QSFP28 port until it latches; the built-in transceivers will perform electrical-to-optical and optical-to-electrical conversion automatically. Route the cable keeping bends gentle and within the manufacturer’s recommended bend radius; secure the cable to avoid strain on connectors. No separate transceiver modules or additional cabling are required for standard QSFP28-to-QSFP28 connections.
Usage recommendations
Use the cable for short-range high-bandwidth links inside or between adjacent racks and avoid long-term tight bends. Verify compatibility with host hardware and firmware, and follow data-centre safety and cable-management practices to maintain performance and longevity.
