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

The BlueOptics Q28-AOC-25M-CI-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. It uses OM3 multimode fibre with a 50 µm core diameter and integrates I/O and O/E conversion in the QSFP28 modules to deliver optical transmission between devices inside a rack or between adjacent racks. The cable features a flame-resistant LSZH outer jacket and is intended for high-performance computing and data centre interconnects where reduced weight, improved flexibility and a small bend radius are required.

Advantages

The product provides 100GBASE-SR4 compatible transmission over a 25 m reach while keeping lower weight and greater flexibility compared with direct-attach twinax solutions. QSFP28 transceiver connectors conform to MSA and SFF/IEEE form-factor standards and include built-in electrical-to-optical and optical-to-electrical conversion for hot-pluggable operation. The LSZH sheath reduces halogen release and smoke in case of fire. Each cable is factory new and tested for functionality and quality prior to shipment.

Suitable for

• Interconnects between network switches, routers or servers within a rack
• Connections between adjacent racks in data centres
• High-performance computing clusters and InfiniBand environments
• Short-range 100G Ethernet and SR4 optical links

Key specifications

• Core diameter: 50 µm
• Application: 100GBASE-SR4 / InfiniBand high-speed transmission
• Sheath: LSZH (low smoke zero halogen), flame resistant
• Bend radius: designed for reduced bend radius compared with twinax
• Weight: lower weight versus direct-attach twinax solutions

How to use

Install the BlueOptics QSFP28-to-QSFP28 active optical cable by inserting each QSFP28 module into the corresponding QSFP28 port on your compatible network device. Ensure devices are powered down or follow hot-plugging procedures recommended by the device manufacturer when connecting or removing the cable. Route the cable to avoid sharp bends and secure it within the rack to prevent strain on connectors. Verify link status on connected equipment and confirm negotiated speeds and lanes after installation.

Recommendations

Handle the AOC by the QSFP28 housings and avoid pulling on the fibre jacket. Maintain bend radii within the manufacturer's guidelines and avoid repeated tight bending. Use this 25 m OM3 AOC where short-range 100G links are required inside or between racks and where LSZH sheathing is preferred for reduced smoke and halogen emissions.
