## Summary description

The BlueOptics Q28-AOC-25M-CN-BO is a 25m InfiniBand fibre optic cable designed for high-speed data transmission. It features OM3 fibre type with a 50 µm core diameter and QSFP28 connectors on both ends, ensuring compatibility with modern networking equipment. Ideal for data centers and high-performance computing environments, it provides reliable connectivity and efficient data transfer.

## Long description

The BlueOptics Q28-AOC-25M-CN-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends, designed for 100G high-speed short-reach connections. It uses OM3 multimode fibre with a 50 µm core diameter and integrates electrical-to-optical and optical-to-electrical conversion within the QSFP28 housings. The 25 m length and LSZH (low smoke, zero halogen) sheath make this QSFP28-to-QSFP28 cable suitable for inter-rack and intra-rack links in data centers and high-performance computing installations.
Advantages
The active optical design reduces weight and increases flexibility compared with direct attach twinax solutions while providing 100GBASE-SR4 compatible performance. Built to MSA and SFF/IEEE guidelines, the cable delivers consistent signal conversion and a smaller bend radius for easier routing. LSZH sheathing improves fire safety in enclosed spaces. Each unit is factory-new and tested for quality and compliance with industry standards.
Suitable for
100G QSFP28 connections between switches, routers and servers
Short-reach links within racks or between adjacent racks (up to 25 m)
Data center fabric and high-performance computing clusters
Environments requiring LSZH sheathing for reduced smoke and halogen
Key specifications
Connector type: QSFP28 to QSFP28 (hot-pluggable)
Length: 25 meters
Fibre type: OM3 multimode, 50 µm core diameter
Application: 100GBASE-SR4 / 100G short-reach data transmission
Sheath: LSZH (low smoke zero halogen), flame resistant
Bend radius: smaller radius than equivalent twinax assemblies for improved cable routing
Integrated transceiver: on-cable I/O and O/E conversion modules
How to use
Install the BlueOptics QSFP28 to QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on networking equipment until the latch engages. No external power or separate transceivers are required because the conversion modules are built into the cable ends. Route the cable following recommended bend radius limits and secure it to prevent strain on the connectors. The cable is hot-pluggable; insert or remove it with the host ports powered according to equipment vendor guidelines.
Usage recommendations
For reliable operation, avoid tight bends and protect the LSZH sheath from sharp edges. Verify hardware port compatibility with QSFP28 and 100GBASE-SR4 standards, and run link tests after installation. Use this AOC for short-distance high-throughput paths where reduced weight and improved flexibility are required compared with copper DAC solutions.
