BlueOptics Q28-AOC-25M-SS-BO καλώδιο οπτικής ίνας InfiniBand 25m OM3

The BlueOptics Q28-AOC-25M-SS-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends, engineered for high-speed 100G data transmission over short distances. It uses OM3 multimode fibre with a 50 µm core diameter and a 25 m cable length, combining a small bend radius and LSZH flame-resistant sheathing for deployment inside racks or between adjacent racks in data centres and high-performance computing environments.

Advantages

This QSFP28-to-QSFP28 AOC provides lower weight and greater flexibility compared with direct-attach twinax solutions while remaining hot-pluggable. The built-in electrical-to-optical and optical-to-electrical conversion within the QSFP28 transceivers ensures signal integrity for 100GBASE-SR4 and related high-speed applications. The cable is manufactured to SFF/MSA and IEEE guidelines and features LSZH (low smoke, zero halogen) outer sheathing for improved safety in confined spaces.

Suitable for

• Interconnects within server racks and between adjacent racks in data centres
• High-performance computing cluster connections requiring 100G bandwidth
• Switch-to-switch or switch-to-server links using QSFP28 ports
• Short-reach 100GBASE-SR4 Ethernet applications

Key specifications

• Connector type: QSFP28 to QSFP28, hot-pluggable
• Length: 25 metres
• Fibre type: OM3 multimode
• Core diameter: 50 µm
• Application: 100GBASE-SR4 / InfiniBand high-speed links
• Sheath: LSZH (low smoke zero halogen), flame resistant
• Built-in I/O O/E conversion for active optical transmission
• Small bend radius and reduced cable diameter compared to passive twinax

How to use

Install the BlueOptics QSFP28 to QSFP28 AOC by aligning the QSFP28 transceiver ends with the QSFP28 ports on your devices and inserting until the connector latches. No separate transceivers or fibre terminations are required because the cable contains integrated transceiver modules that perform the electrical-to-optical and optical-to-electrical conversions. Ensure both ends are fully seated and check link/activity LEDs on connected equipment to confirm the link. Remove the cable by releasing the latch and pulling straight out to avoid stressing the connector.

Recommendations

Use this 25 m OM3 AOC for short-reach, high-bandwidth interconnects inside racks or between adjacent racks. Maintain bend radius guidelines during installation, avoid tight kinks, and route the cable away from heat sources and sharp edges. Verify that connected QSFP28 ports support 100GBASE-SR4 or compatible 100G modes and ensure firmware or driver compatibility on network devices when applicable.
