BlueOptics Q28-AOC-25M-IT-BO Καλώδιο οπτικών ινών InfiniBand 25m OM3

The BlueOptics Q28-AOC-25M-IT-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) engineered for short-range, high-bandwidth connections in data centres and high-performance computing environments. This QSFP28 to QSFP28 25 metre cable uses OM3 multimode fibre with a 50 µm core diameter and integrates hot-pluggable transceiver modules that convert electrical signals to optical and back, enabling 100G data transmission with stable throughput and reduced weight compared with copper twinax solutions.

Advantages

The active optical construction delivers lower weight, greater flexibility and a smaller bend radius compared with direct-attach copper cables, while maintaining compatibility with QSFP28 ports. The built-in I/O and O/E converters follow MSA and SFF/IEEE guidelines, ensuring interoperability across compliant hardware. LSZH sheathing provides a halogen-free jacket with low smoke emission for improved safety in rack environments. Each cable is factory new and tested for functionality and conformity to industry standards.

Suitable for

• High-density rack interconnects within the same rack or between adjacent racks
• 100GBASE-SR4 Ethernet links and InfiniBand short-range connections
• High-performance computing clusters, switch-to-switch and server-to-switch links
• Environments where reduced cable weight and improved bend performance are required

• Compliance: manufactured and tested to MSA, SFF and IEEE relevant specifications; meets common industrial safety and environmental norms

How to use

Connect each QSFP28 plug to compatible QSFP28 ports on network switches, servers, or adapters. Ensure ports are powered down or follow hot-plug procedures recommended by the hardware vendor when inserting or removing the cable. Route the cable with gentle bends respecting the product's minimum bend radius and avoid tight kinks. The integrated transceivers handle the electrical-to-optical conversion transparently; no additional configuration is required beyond standard port setup in the network equipment.

Recommendations

Inspect ports and cable connectors for dust or debris before installation. Use within short-range applications up to 25 m where OM3 performance is suitable; for longer links consider alternative fibre types or active solutions rated for longer distances. Store and route the cable avoiding sharp bends, excessive tension and exposure to temperatures beyond the equipment specifications to maintain performance and longevity.
