## Summary description

The BlueOptics Q28-AOC-7M-F5-BO is a 7-meter InfiniBand fibre optic cable designed for high-speed data transmission. It features OM3 fibre type with a core diameter of 50 µm and QSFP28 connectors on both ends, ensuring reliable connectivity for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-7M-F5-BO InfiniBand fibre optic cable is a 7-meter active optical cable (AOC) with QSFP28 connectors on both ends, designed for high-speed short-range connections in data centers and high-performance computing environments. It uses OM3 multimode fibre with a 50 µm core diameter and supports 100GBASE-SR4 Ethernet and InfiniBand applications. The cable features LSZH (low smoke, zero halogen) sheathing and an integrated I/O O/E converter in each QSFP28 plug to convert electrical signals to optical and back, enabling hot-pluggable, low-weight, and flexible connections between hardware within or between adjacent racks.
Advantages
The active optical design provides lower weight and greater flexibility compared with direct-attach twinax options while maintaining high data rates. Built to MSA, SFF and IEEE guidelines, the QSFP28 connectors incorporate optical-electrical conversion for reliable high-bandwidth transmission. The OM3 fibre and controlled component sourcing ensure consistent performance and a reduced bend radius. The LSZH jacket reduces toxic fumes and smoke emission in case of fire. Each cable is factory new and tested for quality and compliance with CE, RoHS and other common industry standards.
Suitable for
Inter-rack and intra-rack connections in data centers
100G Ethernet (100GBASE-SR4) trunking and switching links
InfiniBand high-performance computing clusters
Server-to-switch and switch-to-switch short-range links
Key specifications
Length: 7 meters
Connector type: QSFP28 to QSFP28 (active optical)
Fibre type: OM3 multimode, 50 µm core
Supported protocols: 100GBASE-SR4 Ethernet, InfiniBand
Sheath: LSZH (low smoke zero halogen)
Design: Integrated O/E and E/O conversion in QSFP28 plugs, hot-pluggable
Application range: Short-distance, within or between adjacent racks
How to use
Ensure compatible QSFP28 ports on both devices and that the equipment supports 100GBASE-SR4 or the intended InfiniBand profile. With equipment powered as recommended by the manufacturer, align and insert each QSFP28 plug into the corresponding port until it seats securely; the built-in transceiver will negotiate link parameters automatically. Avoid tight bends near connector heads and respect the minimum bend radius for OM3 fibre. If a link does not establish, verify port settings, firmware compatibility and that the cable is fully inserted and not damaged.
Usage recommendations
Handle the BlueOptics AOC by the connector housing rather than the cable jacket, avoid sharp bends and excessive pulling force, and store coiled without tight loops. Use this cable for short-range 100G links where reduced weight, flexibility and hot-pluggable operation are required. For environments with strict fire safety requirements, LSZH sheathing reduces smoke and halogen exposure.
