Optical Line Protection (OLP) Card
GROWSFIBER's optical line protection (OLP) card is used for network transmission line protection, which can monitor optical power and automatically switch optical lines. The product can monitor the optical power of the working optical fiber and the spare optical fiber in real time. When the optical power of the working optical fiber is lower than the set switch threshold, the system will give an alarm and automatically switch to the spare optical fiber to realize the line protection of the optical transmission system.
