Optical Line Protection interface card
olp
Product Description:
OLP Optical Protection Board is a protection system designed and manufactured by Orionet for optical line backup. It has an advanced automatic optical path switching module, which is an optical device used in fiber optic communications to switch optical paths. Automatically detect the signal states of the optical signals of the primary and secondary optical systems and perform immediate switching of the optical paths to protect the primary optical cable from full impedance failure and protect the system from normal operation and improve service quality. Its advantage is that optical signals can be directly converted into light using optical circuits, small size, used in many optical transmissions.
OLP 1:1 protection system is designed for low loss and redundancy protection in optical communication lines. The OLP1:1 type protection board injects light into the backup line using selectable receiver and emitter mode to control the backup line fault. When an error occurs in the working optical fiber, the receiver and transmitter quickly switch to the standby fiber to ensure uninterrupted communication.
