7221 Optical Circuit Switch

The N*M intelligent optical cross-connect (OXC) device is a product that utilizes an optical switching matrix to achieve optical path switching. This device provides serial and network interfaces, enabling local and remote control through client access. It ultimately achieves strict non-blocking bidirectional cross-connect for N (input) * M (output) fiber routing. Optical switches are primarily used for multiple optical monitoring in optical transmission systems, automatic switching of local area networks with multiple light sources/detectors, and optical sensing in dynamic multipoint monitoring systems. They are also employed in optical test systems for fiber optic cables, optical equipment, networks, and field engineering cable testing, as well as for the installation and adjustment of optical devices.
