Product overview
OLP-Optical Line Protection is a product that is used in the protection of network transmission line, the product can realize optical power monitoring and automatic switching. In optical communication network, OLP real-time monitoring optical power of working optical fiber and standby optical fiber. When the optical power value of working optical fiber is below the set switching threshold, the system raise the alarm prompt and switches to standby fiber automatically, which achieve line protection of optical transmission system.
Note: the wavelength of PD1 and PD2 need to be specially customized, generally choose one of the Site A wavelength as the monitoring wavelength.
