Product description:


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.
