High Aggregation and Long-distance Transmission

The particularities of the optical transmission network determine that both the lines and equipment needed for the optical transmission network must have extremely high reliability. However, within the existing network, fiber damage, line interruption, equipment power failure, board failure, etc., seriously affect the stability of the transmission network. The intelligent optical protection system provided by FS ensures reliable access to the transmission network and can quickly restore damaged lines and effectively guarantee the stability of the transmission network.

This solution uses FS's optical line protection (OLP) system to monitor both the active and standby optical fibers in real-time, effectively avoiding the simultaneous blocking of both the active and standby routes. When a line interruption or a sudden large attenuation of the optical signal strength is detected, the system will automatically switch to the standby route to ensure smooth business.
