## Summary description

The BlueOptics Q28-AOC-25M-CP-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, providing reliable connectivity for data centers and high-performance computing environments. With a core diameter of 50 µm, this cable ensures optimal signal quality and performance.

## Long description

The BlueOptics Q28-AOC-25M-CP-BO InfiniBand fibre optic cable is a 25 metre active optical cable (AOC) with QSFP28 connectors on both ends designed for short-range, high-bandwidth connections. Using OM3 multimode fibre with a 50 µm core diameter, this AOC supports 100G data transmission for rack-to-rack or in-rack links in data centers and high-performance computing setups. The cable integrates optical transceiver modules that convert electrical signals to optical and back, allowing hot-pluggable operation and reduced weight compared with copper twinax solutions.
Advantages
The cable provides 100G-capable performance over multimode OM3 fibre with lower latency and a smaller bend radius than many direct-attach copper alternatives. Built-in I/O and O/E conversion in the QSFP28 ends simplifies connectivity and ensures compatibility with QSFP28 ports that follow MSA and SFF/IEEE guidelines. The cable sheath is LSZH rated, providing halogen-free, low-smoke behaviour in case of fire, and the assembly undergoes factory testing to verify signal integrity and interoperability.
Suitable for
High-performance computing clusters and InfiniBand networks
100GBASE-SR4 Ethernet short-reach links within or between adjacent racks
Data centre top-of-rack (ToR) and spine-layer connections
Server-to-switch and switch-to-switch high-bandwidth links
Key specifications
Length: 25 metres
Connector type: QSFP28 to QSFP28 (active optical transceiver ends)
Fibre type: OM3 multimode
Core diameter: 50 µm
Supported data rate: 100 Gbps (100GBASE-SR4 compatible)
Sheath material: LSZH (halogen-free, low smoke)
Cable type: Active Optical Cable (AOC) with built-in electrical/optical conversion
How to use
Install the cable by inserting each QSFP28 end into compatible QSFP28 ports on devices such as switches, routers or server NICs. The transceiver ends are hot-pluggable; ensure ports are powered and configured according to the host hardware instructions before link activation. Avoid tight bends and maintain manufacturer-recommended bend radius to preserve optical performance. No separate transceivers or fibre termination tools are required because the conversion modules are integrated into the cable ends.
Usage recommendations
For optimal reliability, route the cable within cable trays or rack managers to prevent repeated bending and mechanical stress. Verify compatibility with QSFP28 ports and firmware support for active optical cables on connected equipment. Use factory-tested AOCs for short-reach 100G links and replace if connector contacts show wear or if the link experiences intermittent errors despite configuration and diagnostics.
