Optical Line Protection (OLP)

The Optical Line Protection (OLP) module is designed to provide backup protection for optical fiber lines. It utilizes advanced optical path automatic switching modules to detect the status of primary and backup optical paths. In the event of a failure in the primary optical cable, the OLP instantly switches to the backup path, ensuring uninterrupted system operation. This module is critical for maintaining high availability and reliability in optical networks.
