## Summary description

The BlueOptics Q28-AOC-7M-NK-BO is a 7m InfiniBand/fibre optic cable featuring OM3 fibre type and QSFP28 connectors. It is designed for high-speed data transmission in data centers and networking applications. With a core diameter of 50 µm, it ensures efficient signal quality and performance.

## Long description

The BlueOptics Q28-AOC-7M-NK-BO is a 7 m active optical cable (AOC) with QSFP28-to-QSFP28 connectors and OM3 multimode fibre (50 µm core). It is engineered for short-range, high-speed data transmission in data centres and rack-to-rack networking environments. The cable implements QSFP28 transceiver modules with built-in electrical-to-optical and optical-to-electrical conversion and supports 100GBASE-SR4 Ethernet applications while offering reduced weight and greater flexibility compared with direct attach twinax solutions.
Advantages
The BlueOptics AOC combines high data throughput with a compact form factor and a small bend radius, enabling dense cabling in rack environments. LSZH (low smoke zero halogen) jacketing improves fire-safety characteristics by reducing smoke and halogen emissions. Conformance to SFF/MSA and IEEE specifications ensures interoperability with compatible QSFP28 ports. Factory testing and use of branded optical components contribute to consistent performance and reliable signal integrity over the stated 7 m length.
Suitable for
100GBASE-SR4 short-reach Ethernet links within racks
High-density top-of-rack and end-of-row switch interconnects
Server-to-switch or switch-to-switch connections in data centres
Environments where reduced cable weight and improved flexibility are required
Key specifications
Connector type: QSFP28 to QSFP28 with integrated transceivers
Fibre type: OM3 multimode fibre
Core diameter: 50 µm
Length: 7 m
Supported standard: 100GBASE-SR4 Ethernet
Jacket: LSZH (low smoke, zero halogen)
Bend radius: optimized for small radius routing (manufacturer guidance applies)
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port until it seats securely; the integrated module handles signal conversion automatically and is hot-pluggable. Route the cable with appropriate bend-radius clearance and secure it within the rack or cable management hardware to avoid strain on the connector ends. No external transceivers or additional configuration are required beyond verifying port compatibility and link settings on the connected devices.
Usage recommendations
For optimal performance, use the BlueOptics AOC in short-reach 100G links as intended, avoid sharp bends or excessive pulling force, and keep the connector endfaces clean and protected when unplugged. Confirm that connected QSFP28 ports support AOC modules and 100GBASE-SR4 operation; follow device vendor guidance for firmware and link negotiation settings.
