## Summary description

The BlueOptics Q28-AOC-7M-MT-BO is a 7m 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 reliable connectivity for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-7M-MT-BO InfiniBand fibre optic cable 7m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends, engineered for short-distance high-speed data links in racks and between adjacent racks. It uses OM3 multimode fibre with a 50 µm core diameter and integrates optical transceiver electronics in each connector to convert electrical signals to optical and back. The cable is intended for 100GBASE-SR4 Ethernet and InfiniBand environments where reduced weight, improved flexibility and a small bend radius are required compared to direct attach twinax solutions.
Advantages
The integrated I/O and O/E converters in the QSFP28 connectors provide reliable signal conversion and hot-pluggable operation without separate transceivers. The OM3 multimode fibre and active transceiver design enable consistent 100 Gbps performance over the specified 7 m length. The cable’s LSZH (low smoke zero halogen) sheath reduces smoke and toxic gas emission in case of fire and meets common safety requirements. Compared to passive twinax alternatives, this AOC offers lower weight, greater flexibility and a smaller bend radius while complying with SFF/MSA and IEEE specifications.
Suitable for
Short-reach 100GBASE-SR4 Ethernet links within server racks
InfiniBand high-performance computing interconnects between adjacent racks
Data centre patching and equipment interconnect where QSFP28 ports are available
Environments requiring LSZH cabling and reduced electromagnetic interference
Key specifications
Cable type: Active Optical Cable (AOC) with QSFP28 to QSFP28 connectors
Length: 7 meters
Fibre type: OM3 multimode fibre
Core diameter: 50 µm multimode
Supported protocol: 100GBASE-SR4 Ethernet and InfiniBand high-speed links
Sheathing: LSZH (low smoke, zero halogen) flame resistant jacket
Connector features: Hot-pluggable transceiver modules with built-in O/E and E/O conversion
Mechanical: reduced bend radius and smaller diameter compared with twinax DAC
How to use
Install the QSFP28 connectors into compatible QSFP28 ports on switches, routers or host adapters until they click into place. Ensure both ends are fully seated and that the cable routing avoids sharp bends below the recommended bend radius. The active optics are hot-pluggable; the connected devices will negotiate link parameters automatically according to the supported protocols. No additional external power or separate transceivers are required beyond the connected equipment.
Usage recommendations
Handle the cable by the connector housings and avoid excessive pulling on the fibre jacket. Maintain the LSZH sheath integrity and follow rack cable management practices to prevent tight loops or kinks. Verify that connected equipment supports QSFP28 AOC modules and 100GBASE-SR4 or InfiniBand link modes before deployment.
