The OLP optical protection board is a protection system developed by FIBERWDM for fiber optic line backup. It adopts advanced optical automatic switching modules and is an optical device used for primary and backup optical path switching in the field of fiber optic communication. It can automatically identify the signal status of the primary and backup system optical paths and perform instantaneous switching of the optical path to ensure the normal operation of the primary optical cable in the event of a complete obstruction, thereby improving the service quality of the service provider. The OLP optical line protection board is widely used in primary and backup protection of various trunk lines and in networks requiring various optical path switching. Its advantages lie in the direct utilization of optical signals in the optical line, compact size, and cost-effectiveness, making it widely used in various optical transmission fields.
