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

The AOC CBO QSFP28 BlueOptics BO282803L20M 100G active optical cable provides a 100 Gbps connection over a 20 m multimode fiber link. Engineered for high-density environments, this QSFP28 AOC supports reliable, low-latency data transmission between servers, switches and storage systems. Compared with equivalent copper interconnects, the active optical cable reduces power consumption and electromagnetic interference, making it suitable for modern data center topologies and aggregation layers where stable 100G links are required.

Advantages

This BlueOptics QSFP28 active optical cable ensures consistent 100G throughput with low insertion loss and high signal integrity over a 20 m reach. The AOC offers lower power draw and reduced heat dissipation compared with copper DACs, while its optical medium eliminates susceptibility to electromagnetic interference. Hot-pluggable QSFP28 connectivity simplifies installation and replacement in dense rack environments, and its industrial-grade construction supports reliable continuous operation in data center conditions.

Suitable for

• High-speed server-to-switch connections within data center racks
• Switch-to-switch aggregation and spine-leaf architectures
• Interconnects between switches and storage arrays
• High-density patching in network distribution panels

Key specifications

• Data rate: 100 Gbps duplex
• Connector type: QSFP28 form factor (hot-pluggable)
• Medium: active optical cable (fiber-based)
• Maximum reach: 20 meters
• Latency: low, suitable for latency-sensitive applications
• Power consumption: lower than comparable copper direct attach alternatives
• EMI susceptibility: negligible compared with copper solutions

How to use

Install the QSFP28 AOC by aligning the connector with the QSFP28 port on each device and inserting until the latch engages. Ensure both ends are fully seated and that ports are powered and configured for 100G operation in the host devices. No separate transceivers or fiber patch cables are required; the cable integrates the optical transceivers and fiber in a single assembly. Verify link status and perform standard network checks to confirm the 100G connection is operational.

Recommendations

Route the cable to avoid sharp bends and excessive stress on the connectors; maintain the manufacturer’s minimum bend radius for optimal optical performance. Use in temperature-controlled rack environments and avoid exposure to fluids or contaminants. When replacing or moving the cable, handle the QSFP28 end gently and verify link negotiation and firmware compatibility on both connected devices.
