Abstract
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.
