Introduction to Optical Line Protection
Optical line protection protects line fibers between adjacent stations by using the dual fed and selective receiving function of OLP boards.
Availability
This section describes the equipment type that support the optical line protection function.
Function Implementation
The optical line protection occupies two pairs of line fibers (working and protection) to provide protection for line signals.
Configuring Optical Line Protection
This section describes the configuration of optical line protection (OLP), including how to create, delete and modify parameters as well as the description of parameters.
Verifying Optical Line Protection Switching
This section takes a ring network formed by two OTM stations to describe the test procedure of the optical line protection switching.
