AOC CBO BlueOptics BO282803L20M 100G QSFP28 active optical cable, 20 m

The AOC BlueOptics BO282803L20M 100G QSFP28 active optical cable is a factory-terminated fiber solution that delivers a 100 gigabit link over a 20 m optical segment. It integrates QSFP28 transceivers with a fixed duplex/multi-fiber optical assembly to provide high-bandwidth, low-latency connectivity between switches, servers and storage systems. The cable is intended for short- to mid-reach interconnects in data centres and telecom racks where single-cable 100G connections simplify installation and reduce issues associated with electrical copper links.

Advantages

The integrated QSFP28 transceivers eliminate separate module handling and reduce potential connector mismatches. Optical transmission over 20 m provides immunity to electromagnetic interference and lower power dissipation compared with equivalent copper assemblies. The fixed-form AOC design offers predictable signal performance with minimal configuration, enabling faster deployment of 100G links while maintaining compatibility with QSFP28 ports.

Suitable for

• Inter-switch links in data centre topologies
• Server-to-switch high-speed connections
• Storage area network (SAN) uplinks and aggregation
• Telecom rack short- to mid-reach interconnects

Key specifications

• Data rate: 100 Gbit/s over QSFP28 interface
• Cable type: active optical cable with integrated transceivers
• Length: 20 metres optical link
• Connector format: QSFP28 plug-to-plug compatible with QSFP28 ports
• Transmission: optical single-mode/multi-fibre assembly for short- to mid-reach
• Latency: low-latency optical interconnect suitable for high-throughput environments

How to use

Install the AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on the networking devices until the latch engages. Ensure ports are powered and configured for 100G operation according to the equipment vendor's interface settings. No separate transceiver modules or fibre termination are required; handle the cable by the connector backshell and avoid sharp bends during routing. If link negotiation does not occur, verify port configuration, optical lane mapping and vendor compatibility settings in the switch or server management interface.

Recommendations

Route the cable to avoid tight bend radii and mechanical strain; maintain manufacturer-recommended bend radius and secure the cable to prevent movement. Confirm 100G QSFP28 port compatibility and update host or switch firmware if required. Use in temperature-controlled rack environments and inspect connectors for contamination before insertion to ensure reliable optical performance.
