| Abstract: | Through the development of the last few years, the PON technology has been becoming mature and been widely used. It is necessary to realize the technology of PON protection switching in order to guarantee the operational stability of system in engineering application and take countermeasures against correspondence malfunction. This thesis mainly discussed the PON protection switching technology. Design of the flow and mechanism of PON protection switching, realize the accurate, safe, fast PON protection switching. |
