1+1 Optical Line Protection System


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.



  • 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.
