METHOD OF TRANSPORT AND RECEPTION OF SERVICE SYNCHRONAL DIGITAL HIERARCHY (SDH) IN OR THROUGH A PASSIVE GIGABIT OPTICAL NETWORK (GPON), AND SDH DESERT TRANSMISSION DEVICE
METHOD OF TRANSPORT AND RECEPTION OF SERVICE SYNCHRONAL DIGITAL HIERARCHY (SDH) IN OR THROUGH A PASSIVE GIGABIT OPTICAL NETWORK (GPON), AND SDH DESERT TRANSMISSION DEVICE
sdh (synchronous digital hierarchy) service transport and reception method via pon (passive optical network), sdh service method on pon, sdh service transmission and reception device, sdh data frame mapping method in gem frame. The present invention relates to a method for transporting a synchronous digital hierarchy service in a passive optical network comprising: directly mapping a tax unit carrying the data of a synchronous digital hierarchy service to the frame payload to perform sdh service data transport over a gigabit passive optical network. the encapsulation is removed by the opposite procedure at one receiving end. there is also a sending apparatus and a receiving apparatus for synchronous digital hierarchy service, and a method for mapping the synchronous digital hierarchy service data frame to a passive optical network data frame. can be merged directly with the synchronous digital hierarchy network because the standard frame structure of the tax unit of a synchronous digital hierarchy is applied, and virtual container extraction comprising synchronous digital hierarchy service data, and service clock synchronization. are performed conveniently based on the tax unit's pointer adjustment mechanism.
