## Summary description

The BlueOptics Q28-AOC-25M-GM-BO is a 25m InfiniBand/fibre optic cable featuring OM3 fibre type and QSFP28 connectors. It is designed for high-speed data transmission and reliable performance in data centers and networking environments. With a core diameter of 50 µm, it ensures optimal signal quality and minimal loss.

## Long description

The BlueOptics Q28-AOC-25M-GM-BO is a 25 meter active optical cable (AOC) with QSFP28 connectors at both ends and OM3 multimode fibre (50 µm core). It is built for short-reach 100G links in data centre and networking environments, providing optical conversion within the connector housings to support high-speed 100GBASE-SR4 applications. The cable uses LSZH (low smoke, zero halogen) sheathing and is intended for connections inside racks or between adjacent racks where lower weight and improved flexibility are required compared with direct-attach copper twinax alternatives.
Advantages
The integrated transceiver modules convert electrical signals to optical and back, enabling hot-pluggable 100G connections without separate SFP/QSFP transceivers. The OM3 multimode fibre with 50 µm core diameter delivers low loss and consistent signal quality for short-distance high-bandwidth transmission. LSZH jacket material reduces toxic fumes and smoke in the event of fire, while the AOC construction offers reduced diameter, smaller bend radius and lower weight than equivalent twinax cables. Each unit is factory tested and conforms to common industry standards for interoperability and safety.
Suitable for
100G server-to-switch and switch-to-switch connections within the same rack
Inter-rack short-reach links in data centres (adjacent racks)
High-density networking environments requiring flexible, low-weight cabling
Applications that require QSFP28 to QSFP28 direct optical links for 100GBASE-SR4
Key specifications
Cable type: Active Optical Cable (AOC)
Connector type: QSFP28 to QSFP28 (hot-pluggable)
Length: 25 metres
Fibre type: OM3 multimode fibre
Core diameter: 50 µm
Application: 100GBASE-SR4 / 100 Gigabit Ethernet short-reach
Sheath: LSZH (low smoke zero halogen), flame resistant
Bend radius: reduced relative to twinax; designed for tight routing in racks
How to use
Install the cable by inserting each QSFP28 connector into the matching QSFP28 port on the network devices until the connector latches. Ensure both ends are seated firmly and that device firmware or port settings are configured for 100G operation where required. Route the cable through rack pathways avoiding sharp bends below the recommended bend radius. Because the cable contains active optical transceivers, avoid exposing connectors to dust; use protective caps when ports are not in use. No external transceivers are required—power and optical conversion take place in the cable connectors.
Usage recommendations
Use this AOC for short-distance 100G links inside data halls and between adjacent racks. Verify compatibility with your switches and NICs that accept QSFP28 AOC assemblies, and follow vendor guidance for port configuration. For longer distances consider single-mode fibre solutions. Store and handle the cable carefully to maintain bend radius and cleanliness of optical interfaces.
