Abstract

In recent years, the speed and capacity of fiber optic communication systems have been greatly improved, but in the event of a failure requiring a switching, the 50ms switching time defined by the International Telecommunication Union Telecommunication Standards Branch (ITU-T) can cause a large amount of service data loss compared to low-speed transmission. Therefore, how to minimize the switching time has also become a key issue in protecting the switching. In this paper, we use a magneto-optical switch (MO-Switch) as the core device for protection switching, and design a state machine using FPGA/CPLD to control and design an automatic protection switching (APS) protocol in hardware to realize a 1+1 unidirectional or bidirectional linear protection switching system. The proposed scheme finally achieves a switching time of about 1.5ms, which achieves a performance improvement of more than 95% compared to the standard 50ms and reduces the loss caused by the failure of high-speed fiber optic communication systems.
