Document Type and Number:
WIPO Patent Application WO/2010/121512
Kind Code:
A1
Abstract:
A method and system for transmitting signals in an Optical Transport Network (OTN) are disclosed in the embodiments of the present invention, solving the problem of Optical Multiplex Section (OMS) layer overhead and the functions represented thereby not being correctly applied to the operation, administration and maintenance of the OMS layer. A solution is that: one Optical Transmission Section (OTS) layer corresponds to multiple Optical Multiplex Section (OMS) layers of different wave bands, wherein overheads and payloads of different OMSs are independent of each other (S101); when a certain node unit has wavelength services or sub-wavelength services, the OMS corresponding to said wavelength is determined and then terminated and regenerated, while other OMSs are not terminated or regenerated (S102). The present invention is used to transmit optical signals in an OTN.
