AOC CBO BlueOptics QSFP28 BO282803L10M 100G 10 m active optical cable

The AOC CBO BlueOptics QSFP28 BO282803L10M 100G 10 m active optical cable is a factory-terminated duplex optical link that provides native 100 Gbps connectivity over a 10-metre reach. It features QSFP28 connectors at both ends and is intended for short-reach, high-bandwidth interconnects in data centres and enterprise networks. The cable combines optical transmission with an integrated electrical interface to deliver low latency and improved power efficiency compared with equivalent copper direct-attach assemblies.

Advantages

This active optical cable supports full 100G throughput with QSFP28 form-factor compatibility, enabling straightforward integration with switches, routers and servers that accept QSFP28 ports. Its 10 m length allows flexible rack-to-rack or equipment-to-equipment placement without additional transceivers or patching. The optical medium reduces crosstalk and electromagnetic interference, providing stable signal integrity in dense rack environments while keeping power consumption lower than many copper alternatives.

Suitable for

• 100G server-to-switch connections in data centres
• Rack-to-rack interconnects within the same room or adjacent rooms
• High-density switch-to-switch uplinks and spine-leaf architectures
• Equipment migration where native QSFP28 ports are available

Key specifications

• Data rate: 100 Gbps (aggregate)
• Connector type: QSFP28 to QSFP28 (duplex optical)
• Length: 10 metres
• Type: Active optical cable (AOC)
• Reach: Short-reach (10 m) for intra-rack and rack-to-rack links
• Latency: Low-latency optical transmission suitable for high-performance networking
• Power: Lower power consumption compared with equivalent copper DACs

How to use

Ensure both network devices have compatible QSFP28 ports and that the ports are configured for 100G operation. Remove protective caps from the QSFP28 connectors, align the connector keying with the port and insert the cable until it seats fully and the latch engages. Confirm link status via device LEDs or management interfaces and verify correct speed and lane configuration in the host system. When removing the cable, press the connector latch and gently withdraw to avoid stressing the port.

Usage recommendations

Use the cable within the recommended 10 m reach and avoid sharp bends or kinks to maintain optical performance. Keep connectors capped when not in use and handle by the connector housing rather than the fibre to reduce contamination. Verify firmware and compatibility notes for your switch or server vendor where vendor interoperability lists are required.
