    摘要： 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.

    摘要： Provided are a method and apparatus for increasing transmission capacity for large-capacity high-speed signal transmission in an optical transport network (OTN). A method and apparatus for increasing transmission capacity are needed, which can transmit a large-capacity high-speed signal in order to transmit a signal through a united OTN by adapting signals from various tributary signal networks which have been independently operated for voice, image, or data transmission. Although various types of techniques such as Time Division Multiplexing (TDM), Wavelength Division Multiplexing (WDM), and an optical Printed Circuit Board (PCB) method have been performed, the techniques have various limitations. Therefore, a method and apparatus is provided for embodying a large-capacity optical transmission network, which overcome the limitations by using a Virtual Concatenation (VC) method.
