BlueOptics Q28-AOC-25M-F5-BO InfiniBand-kuituvalokaapeli 25 m OM3

The BlueOptics Q28-AOC-25M-F5-BO InfiniBand fibre optic cable 25m OM3 is a 25‑metre active optical cable (AOC) with QSFP28 connectors on both ends designed for short‑reach 100G data links. It uses OM3 multimode fibre with a 50 µm core diameter and integrates optical/electrical conversion in the QSFP28 housings to enable high‑speed connections within racks or between adjacent racks in data centres and high performance computing environments. The cable sheath is LSZH (low smoke zero halogen) for reduced smoke and halogen emissions in case of fire.

Advantages

This BlueOptics QSFP28 to QSFP28 AOC provides 100GBASE‑SR4 compatible transmission with lower weight and greater flexibility compared with passive direct attach twinax solutions. Built‑in transmitter/receiver modules in each connector perform reliable electrical‑to‑optical and optical‑to‑electrical conversion, while adherence to MSA and SFF/IEEE specifications ensures interoperability. The cable offers a small bend radius, reduced diameter and flame‑resistant LSZH sheathing for safer deployment in dense rack environments. Each unit is factory new and tested for functionality and quality prior to shipment.

Suitable for

• Short‑reach 100G connections within server racks or between adjacent racks
• High performance computing clusters and InfiniBand fabrics
• Data centre top‑of‑rack and spine interconnects compatible with QSFP28 ports
• Environments requiring LSZH sheathing for safety and low smoke emission

Key specifications

• Length: 25 metres
• Connector type: QSFP28 to QSFP28 (hot‑pluggable)
• Supported data rate: 100G (100GBASE‑SR4 compatible)
• Fibre type: OM3 multimode fibre
• Core diameter: 50 µm
• Sheath material: LSZH (low smoke, zero halogen)
• Small bend radius and reduced cable diameter compared with twinax solutions

How to use

Install the BlueOptics AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on network switches, NICs or host adapters until the latch engages. Because the cable contains integrated I/O and O/E conversion, no separate transceivers are required. Ensure both ends are connected to compatible QSFP28 interfaces and that devices are powered and configured for the intended 100G link. Route the cable to avoid excessive bending beyond the specified bend radius and secure it to prevent strain on connectors.

Recommendations

Use this OM3 QSFP28 AOC for short‑distance 100G interconnects where reduced weight and improved flexibility are important. Maintain manufacturer‑recommended bend radius, verify port compatibility with QSFP28 and 100GBASE‑SR4 signalling, and avoid prolonged exposure to extreme temperatures or mechanical stress to ensure long service life.
