FAQ

What electrical interface does this AOC support?

The cable supports the 400GAUI-8 electrical interface with PAM4 signaling and data rates of up to 53.125Gbps per channel.

What optical technology does it use?

The AOC uses 850nm VCSEL transmitter arrays and integrated photodetector arrays to convert electrical signals to optical signals and back within the cable assembly.

What cable lengths are available?

The AOC is available in lengths from 1 meter to 50 meters, providing flexibility for different rack and data center layouts.

Are separate optical transceiver modules required?

No. The optical conversion components are integrated into the QSFP-DD ends of the AOC, eliminating the need for separate transceivers and fiber patch cables.

Why use an AOC instead of a high-speed copper cable?

The AOC provides a lightweight and flexible alternative for longer short-range connections, with optical transmission that can simplify cable management and support higher-density data center deployments.
