1 General
1.1 System Description
OLP (Optical Fiber Line Auto Switch Protection System) is a product that used in the protection of optical transmission line, it can realize optical power real-time monitoring and automatic optical fiber line switching.
In optical transmission network, the OLP monitor the optical power of the Primary and Secondary fiber in real time. When the Primary is accidentally broken or the performance is degraded, the OLP will automatically switch the working channel from Primary to Secondary to realize the protection of optical fiber line.
1.2 Advantages
l Working in the optical layer, transparent transmission to optical signals.
l High optical performance.
l Carrier grade switching speed.
l Support dual power supplies for redundancy.
l Support NMS for unified OAM.
1.3 Applications
l Optical fiber line auto switch protection.
l Real-time monitoring of fiber quality by optical power.
l Emergency dispatching of working routes.
