ABSTRACT:
A method of carrying SDH services in PON is provided, in which tributary units carrying SDH service data are mapped into payload part of GEM frames, thereby implementing transmission of SDH services in GPON. De-capsulation is performed in reverse process at receiving end. A device of receiving or transmitting SDH services and a method of mapping SDH data frame into PON data frame are also provided. The present invention may be merged with SDH network directly since standard SDH tributary unit structure is adopted, and extraction of virtual containers that includes SDH service data and synchronism can be accomplished conveniently based on pointer adjustment mechanism adopted by tributary units.
