AOC CBO QSFP-100G-AOC-20M active optical cable 20 m QSFP28 for 100G interconnects

The AOC CBO QSFP-100G-AOC-20M active optical cable is a 20-metre QSFP28 assembly engineered for 100 Gigabit Ethernet interconnects in data center environments. With QSFP28 connectors at both ends, this BlueOptics cable supports high-speed links between servers, switches and optical transceivers, offering the benefits of optical transmission over copper for short to medium reach connections within and between racks.

Advantages

This active optical cable delivers high aggregate bandwidth for 100G networks while reducing electromagnetic interference and crosstalk compared with copper alternatives. The optical medium enables lower latency and more stable signal integrity over the 20 m length, and the QSFP28 form factor ensures compatibility with standard 100G QSFP ports. The integrated design simplifies cabling management by replacing multiple copper cables and reducing heat and weight in dense rack deployments.

Suitable for

• 100 Gigabit Ethernet uplinks between switches and routers within a data hall
• Interconnects between adjacent server racks and top-of-rack switches
• High-speed links for server-to-switch connections in blade and rack systems
• Short- to medium-reach optical links in enterprise and colocation data centers

Key specifications

• Connector type: QSFP28 to QSFP28 optical connector
• Nominal data rate: 100 Gbit/s aggregate
• Length: 20 metres
• Cable type: active optical cable (AOC) with integrated transceivers
• Transmission medium: multimode/mode-optimized optical fibers for short-reach 100G
• Typical use: in-rack and between-rack interconnects up to 20 m

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP port on the network devices until the connector latch engages. Ensure that both ends are seated firmly and that port link indicators show an active 100G connection. Avoid tight bends and maintain proper bend radius along the cable run; route the cable through cable management channels or tie points to prevent strain on the connectors. When removing the cable, release the latch before pulling to avoid damaging the connector or port.

Recommendations

For reliable operation, use the cable within the specified 20 m reach and in environments that meet standard data center temperature and humidity ranges. Verify device compatibility with QSFP28 100G ports and confirm that firmware or drivers on connected equipment support active optical cable detection when applicable. Handle connectors by the housing and avoid touching the fiber ends.
