Optical Line Protection System (OLP) uses vacant optical fiber from different route to build a backup path. By real-time monitoring the power status in working fiber, it can automatically switch from working fiber to backup fiber when the power value of working fiber lower than  a user defined threshold . OLP will provide you a more reliable, flexible and high secure optical transmission network .It is widely used for protecting backbone and important business line.
