AOC cable CBO Marconi QSFP-100G-AOC-20M 20m — active optical cable for QSFP ports, 20 m length

AOC cable CBO Marconi QSFP-100G-AOC-20M is a 20-meter active optical cable designed for QSFP ports and 100G connectivity. It provides a fixed-length optical link that replaces multiple fiber-patch-cable components with a single lightweight assembly. The cable is intended for short-reach connections inside data centers and network rooms, offering low latency and immunity to electromagnetic interference compared with copper alternatives.

Advantages

The AOC design delivers a compact, factory-terminated connection that simplifies installation and reduces cable management complexity. Being optical, it minimizes signal degradation over the 20 m reach and avoids electromagnetic interference. The cable supports high-density QSFP interfaces and helps maintain consistent 100G throughput with low power consumption compared to transceiver-plus-fiber solutions.

Suitable for

• Switch-to-switch links within the same rack or across adjacent racks
• High-speed server-to-switch connections in data centers
• Top-of-rack (ToR) interconnects and aggregation layer cabling
• Short-reach links where fixed-length, plug-and-play optical cables are preferred

Key specifications

• Interface type: QSFP form-factor connectors for 100G ports
• Cable type: Active optical cable (AOC) with integrated transceivers
• Link length: 20 meters
• Data rate: 100 Gbit/s line rate support
• Latency: low propagation delay suitable for high-throughput switching environments
• Physical: lightweight, flexible fiber assembly for dense rack installations

How to use

Install the AOC by inserting each QSFP connector into the corresponding 100G QSFP port on the networking devices. Ensure that ports are powered and that devices support AOC or QSFP-based 100G links. No additional transceiver modules or fiber patching is required; the cable is a factory-terminated plug-and-play solution. Verify link status on connected devices and check firmware or driver compatibility if the link does not come up immediately.

Recommendations

For reliable operation, route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer's minimum bend radius. Use proper cable management in rack environments to prevent excessive tension on connectors. Verify compatibility with the QSFP port vendor and, when deploying in dense installations, document port locations to simplify maintenance and future changes.
