Optical Line Protection Board (OLP 1:1)
The OLP optical protection board is a fiber-line backup protection system developed by Huixinte Communications. Its advanced automatic optical-path switching module switches between primary and backup paths in fiber-optic communications. It automatically identifies the optical-signal status of the primary and backup systems and switches paths instantly, keeping the protected system operational during a complete interruption of the primary cable and improving operator service quality. OLP boards are widely used for primary/backup protection of trunk lines and in networks requiring different optical-path switching arrangements. Their ability to directly switch and use optical signals in the optical line, compact size, economy and safety make them suitable for many optical-transmission applications.
