BlueOptics Q28-AOC-25M-MR-BO InfiniBand-kuituoptinen kaapeli 25 m OM3

The BlueOptics Q28-AOC-25M-MR-BO InfiniBand fibre optic cable 25m OM3 is a QSFP28-to-QSFP28 active optical cable (AOC) designed for 100G high-speed links over short distances. It uses OM3 multimode fibre with a 50 µm core diameter and a 25 metre length, combining transceiver modules and optical fibre in a single hot-pluggable assembly. The cable is intended for rack-to-rack or in-rack connections in data centres and high-performance computing environments and features LSZH (low smoke zero halogen) flame-resistant sheathing for reduced smoke and no halogen emissions in case of fire.

Advantages

This active optical cable converts electrical signals to optical signals and back via integrated I/O and O/E converters in the QSFP28 connectors, enabling 100GBASE-SR4 and InfiniBand-compatible transmissions. Compared with direct attach copper twinax solutions it provides lower weight, greater flexibility, a smaller bend radius and improved signal performance over the specified 25 m reach. The QSFP28 transceiver ends are manufactured to industry SFF/MSA and IEEE specifications and the cable is factory-tested to ensure functional reliability.

Suitable for

• Short-range 100G connections between devices within the same rack
• Adjacent rack interconnects in data centre and server room environments
• High-performance computing and InfiniBand cluster links
• Environments requiring low-smoke, halogen-free cabling

Key specifications

• Connector type: QSFP28 to QSFP28 (hot-pluggable)
• Length: 25 metres
• Fibre type: OM3 multimode, 50 µm core
• Supported data rate: 100G (100GBASE-SR4 / InfiniBand-compatible)
• Sheath: LSZH (low smoke zero halogen), flame resistant
• Bend radius: designed for smaller bend radius than equivalent twinax solutions
• Performance: integrated transceivers with electrical/optical conversion for low-loss transmission

How to use

Install the BlueOptics QSFP28-to-QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 ports on your network or compute devices. The cable is hot-pluggable and requires no external power or separate transceiver modules. Ensure proper alignment of the connector latch and secure the cable to avoid strain on the ports. Route the 25 m cable following the recommended bend radius and avoid tight kinks; use cable management within racks to maintain orderly runs and reduce mechanical stress.

Recommendations

Verify compatibility with your hardware vendor for QSFP28 and 100GBASE-SR4 or InfiniBand requirements before deployment. During installation, observe LSZH handling guidelines and avoid exposure to sharp edges, extreme temperatures or mechanical abrasion. Periodic inspection and cleaning of connector endfaces according to manufacturer guidelines will help maintain optimal signal quality.
