Optical Line Protection Equipment (OLP)

1. overview

Optical Line Protection Equipment (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.

olp shown as the figure below

u      features

reduce interrupt time of communication and improve maintenance efficiency with quickly recovering communication

remarkably reduce damage to network caused by fiber failure

increase network reliability and improve service quality

harmless switch between working path and secondary path and convenient for line overhaul and cutover

real-time monitoring power level of fiber

support remote control, easy management and maintenance

transparent transmission
