The OLP optical line protection subsystem launched by Guangzhou Sintai Co., Ltd is based on the advanced development of optical switch technology. It's an automatic monitoring and protection system independent of the communication transmission system and completely based on the physical link of optical cable.
The system can automatically switch the signal to the optical fiber of the protection path when performance deterioration or blocking of the work path is detected. In this way, an optical communication network with high reliability, safety, flexibility, and strong disaster resistance is established.
