Cable AOC CBO QSFP-100G-A20M Cable óptico activo 100G, QSFP28 a QSFP28, 20 m

The AOC cable CBO QSFP-100G-A20M is a 100G active optical cable (AOC) with QSFP28 connectors on both ends and a fixed 20 m length. It establishes a direct 100 Gigabit link between QSFP28 ports without requiring separate transceivers, making it suitable for dense cabling environments in data centers and high-performance network racks. The cable is designed to deliver high throughput with low latency and reduced power consumption compared with equivalent electrical copper links.

Advantages

This active optical cable offers native QSFP28 connectivity for 100G links while removing the need for additional transceiver modules, simplifying installation and reducing component count. Optical transmission across the 20 m span provides lower signal attenuation and electromagnetic immunity compared with copper alternatives, and typically results in lower power draw at the endpoints. The fixed-length AOC reduces rack clutter and supports direct interconnects between switches, routers and servers with compatible QSFP28 ports.

Suitable for

• High-density data center switch-to-switch connections
• Server to top-of-rack or leaf switch links requiring 100G bandwidth
• Router interconnects and aggregation layers in campus or cloud environments
• Short-reach backbone links inside equipment rooms and network cabinets

How to use

Insert each QSFP28 connector into the QSFP28 port on the two devices to be linked, ensuring the connector latch engages. No separate transceivers or patch panels are required — the cable provides an integrated optical link. Confirm both devices support 100G QSFP28 operation and verify link status via device management interfaces or LEDs. For hot-plug operations follow the equipment vendor’s guidance; handle connectors by the housing to avoid contaminating optical interfaces.

Recommendations

Install the cable following standard data center practices: avoid tight bends, maintain recommended bend radius, and route the cable to prevent kinks or mechanical stress. Keep QSFP28 connector end caps on until insertion and, if cleaning is necessary, use products and methods approved for fiber-optic connectors. Verify compatibility with the QSFP28 ports on your switches, routers or servers and consult equipment documentation for supported speed and lane configurations.
