OLP Card

OLP (Optical Line Protection) is a protection system developed by GIGALIGHT for fiber optic line backup. It utilizes advanced optical path automatic switching modules and serves as an optical device for main and backup optical path switching in the field of fiber optic communication. It can automatically identify the status of the main and backup system optical signals and perform instantaneous path switching. This ensures the normal operation of the protection system when the main fiber cable encounters a complete blockage, thereby improving the service quality for operators. OLP optical line protection boards are widely used in main and backup protection for various trunk lines and network configurations requiring different optical path switching. Its advantages lie in the direct utilization of optical signals in the optical path, compact size, cost-effectiveness, and safety. Therefore, it has been applied in numerous fields of optical transmission.
