- Products description -
OLP Optical Protection Board is a protection system developed by Sharetop Technology Co., Ltd. for optical line backup. It adopts advanced optical path automatic switching module, which is an optical device used in optical fiber communication to switch optical paths. Automatically identify the signal states of the optical signals of the primary and backup optical systems, and perform instantaneous switching of the optical paths so as to protect the primary optical cable from full-impedance failure and protect the system from operating normally and improve the service quality of operators. OLP optical line protection board is widely used in a variety of trunk main and backup protection and a variety of optical switching network. Its advantage is that optical signals can be directly converted into light in the use of optical circuits, small size, economic security, it is used in many optical transmission.
The OLP1: 1 type protection board is designed for protection boards with low loss and redundancy in optical communication lines. The OLP1: 1 type protection board uses the selective receiving and emitting mode to inject light into the backup line to monitor whether there is a fault on the backup line. When the working optical fiber occurs Fault, the receiver and the sender quickly switch to the standby fiber, to ensure unobstructed communication.
