1U 4U Optical Line Protection device 1:1 1+1 1-1,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.1:1 | 1+1 | 1-1 | |
