Optical line protection (OLP) system is a new optical line protection subsystem developed with advanced technology of dynamic and synchronous optical switches. When communication quality is lower or equipment breaks down due to accidental fracture or bigger loss of optical fiber in the optical transmission line, the OLP system can switch the primary line to the secondary line within a short time, to ensure normal operation communication of line, which effectively prevent fiber or equipment fault and shorten the recovery time from hours to milliseconds.

Solution Characteristics

·  Real-time monitoring: Real-time monitoring work status of primary and secondary fiber link

·  Compatibility: Compatible with 1:1 OLP, 1+1 OLP, 0dB OLP, OLM, EDFA, Raman amplifier and other function card

·  Scheduling: Support remote and local scheduling function

·  Power-down latching: No affect the switching status of the primary and secondary lines when device power-down, hot-plug function.

Typical Solution 

1、Point-to-point protection – Performance of primary and secondary line is close

2、Point-to-point protection -- Secondary line performance slightly worse than the primary line

3、Point-to-point protection -- The difference between the primary and secondary line is large

4、Point-to-point protection – Primary line cross-station protection OTM-OTM
