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

The BlueOptics Q28-AOC-25M-MA-BO InfiniBand fibre optic cable 25m OM3 is a 25-metre Active Optical Cable (AOC) with QSFP28 connectors on both ends, designed for 100G high-speed transmissions over short distances. It uses OM3 multimode fibre with a 50 µm core diameter and integrates optical-electrical conversion in the QSFP28 modules. The cable features LSZH (low smoke zero halogen) sheathing and is intended for interconnections within racks or between adjacent racks in data centers and high-performance computing environments.

Advantages

This QSFP28-to-QSFP28 AOC provides flexible, lightweight cabling with a smaller bend radius compared to direct-attach twinax solutions. The built-in I/O and O/E converters in the transceiver housings enable hot-pluggable 100GBASE-SR4 operation and stable optical signal transmission over the 25 m distance. The cable is manufactured to industry MSA, SFF and IEEE guidelines and is produced using components from established vendors to ensure consistent performance, reduced weight and improved thermal properties. The LSZH jacket reduces halogen release and smoke in the event of a fire.

Suitable for

• Short-reach 100G interconnects inside racks
• Connections between adjacent server or switch racks
• High-performance computing cluster links
• Data centre switch-to-switch or switch-to-server links

Key specifications

• Cable type: Active Optical Cable (AOC) with integrated transceiver modules
• Connector type: QSFP28 to QSFP28 (hot-pluggable)
• Length: 25 metres
• Fibre type: OM3 multimode fibre
• Core diameter: 50 µm multimode core
• Standard compatibility: 100GBASE-SR4 Ethernet
• Sheath material: LSZH (low smoke, zero halogen)
• Bend radius: smaller bend radius than typical twinax solutions (AOC design)

How to use

Install the BlueOptics Q28-AOC-25M-MA-BO by inserting each QSFP28 connector into the corresponding QSFP28 port on switches, servers or network adapters. The cable is hot-pluggable; ensure that ports support QSFP28 modules and 100GBASE-SR4 operation. Route the cable following recommended bend radius guidelines and avoid tight kinks; secure the cable to rack infrastructure if necessary to prevent strain on connectors. No separate transceiver modules or patch panels are required because the optical-electrical conversion is integrated into the cable ends.

Recommendations

Use this AOC for short-distance 100G links inside racks or between adjacent racks. Confirm compatibility with host devices' QSFP28 ports and check firmware or vendor compatibility lists if applicable. Handle the QSFP28 housings carefully, maintain minimum bend radius, and keep connector dust caps in place when connectors are not mated to protect optical interfaces.
