Abstract
Disclosed are an apparatus and a method for mapping an SDH signal and other 40-Gbps client signals through a single data path. The mapping apparatus supports both a justification byte mapping scheme and a sigma-delta distribution mapping scheme and implements a single data path. Accordingly, power consumption may be reduced by changing each mapping mode in a hitless manner or minimizing logic capacity according to a mapping mode used in the mapping apparatus.
