## Summary description

The BlueOptics Q28-AOC-7M-CO-BO is a 7-meter InfiniBand/fibre optic cable designed for high-speed data transfer. It features OM3 fibre optic 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-CO-BO InfiniBand/fibre optic cable 7m OM3 is a 7‑meter Active Optical Cable (AOC) with QSFP28 connectors on both ends, designed for short‑reach high‑speed interconnects in racks and between adjacent racks. It uses OM3 multimode fibre with a 50 µm core diameter and integrates built‑in electrical‑to‑optical and optical‑to‑electrical conversion within the QSFP28 housings to support 100GBASE‑SR4 Ethernet and InfiniBand links. The cable features a low‑smoke, halogen‑free (LSZH) sheath and a flexible, lightweight construction that provides a smaller bend radius compared to direct‑attach twinax solutions.
Advantages
The Active Optical Cable design reduces weight and increases flexibility compared with direct‑attach copper twinax while maintaining hot‑plug capability. Integrated transceiver electronics follow MSA, SFF and IEEE guidelines to ensure interoperability with compatible QSFP28 ports. The OM3 fibre and internal components are selected from established manufacturers to provide stable signal transmission over the 7 m length, and each cable is factory tested for functionality and compliance with industry standards such as CE and RoHS.
Suitable for
 100GBASE‑SR4 Ethernet connections in data centers
 InfiniBand high‑performance computing interconnects
 Inter‑rack and intra‑rack links between switches and servers
 Environments requiring low smoke, halogen‑free cabling
Key specifications
 Cable type: Active Optical Cable (AOC) with integrated transceivers
 Connector type: QSFP28 to QSFP28 (hot‑pluggable)
 Fibre type: OM3 multimode
 Core diameter: 50 µm
 Length: 7 meters
 Application: 100GBASE‑SR4 Ethernet, InfiniBand
 Sheath: LSZH (low smoke, zero halogen)
 Bend radius: smaller than comparable DAC solutions (improved flexibility)
How to use
Connect each QSFP28 end into compatible QSFP28 ports on the devices to be linked, ensuring connectors are fully seated and latches engaged. The integrated I/O converters handle the electrical‑to‑optical and optical‑to‑electrical signal conversion automatically; no separate transceivers or module configuration is required. Observe vendor instructions for port enablement and link configuration on switches or host adapters and verify link status through device management interfaces after insertion.
Usage recommendations
Route the cable to avoid tight bends and mechanical stress; respect the manufacturer’s recommended minimum bend radius. Use AOC connections for short‑reach, high‑speed links up to 7 m and choose OM3‑rated equipment for best performance. Store and handle the QSFP28 connectors with protective caps when not in use to prevent contamination of optical interfaces.
