1:1 line protection OLP


OLP(Optical Line Protection) is a device used in pairs, one at each end of the optical signal to protect network transmission line. It can realize optical power monitoring and automatic switching. In optical communication network, OLP monitors optical power of optical fiber and standby optical fiber at real time. In case the current optical power of optical fiber is less than pre-set switching threshold value, then alarm is on and it would switch to standby optical fiber automatically to protect optical transmission system line.


GEZHI provides 2 types of line protection: 1:1 line protection and 1+1 line protection. Wavelengths and connectors can be customized to meet special control and applications.The device is available with standard 1U rack mount and Pluggable Module.



  • 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.
