摘要
The 10Gbps SDH transmission system is a synchronous optical transmission device that transmits multiple subordinate (STM-1, STM-4, STM-16) signals configured for synchronous transmission to the other station by multiplying them with the high-speed signal STM-64. On the contrary, it is a device that receives 10Gbps optical signals from the opposite station and demultiplexes them into multiple dependent signals. Each of these dependent signals forms its own frame for the synchronous transmission scheme, and the high-speed signal formed by multiplexing these dependent signals also constitutes a frame for the synchronous transmission scheme. When the slave signals are multiplexed to form a high-speed signal, the frame phase of each slave signal at the front end of the multiplexing must be in the same position so that 10Gbps high-speed multiplexing is normally performed. In the present invention, when the multiplexing of the dependent signals in the 10Gbps optical transmission system by the high speed unit, the frame phase synchronization method can solve the phase difference between each of the configured dependent signal frames, so that the frame phase of each of the dependent signals arriving at the multiplexed input terminal is one position.
