Title:
A method and a device for transmitting and receiving a client signal in an optical transmission network
Document Type and Number:
Japanese Patent JP6086334
Kind Code:
B2
Abstract:
Embodiments of the present invention provide a method and an apparatus for transmitting and receiving a client signal in an optical transport network, and relate to the field of optical transport networks. The transmission method includes: mapping a received client signal into a variable-rate container OTU-N, where a rate of the OTU-N is N times as high as a preset reference rate level, and the value N is a configurable positive integer; splitting the variable-rate container OTU-N into N optical sub-channel transport units OTUsubs by column, where a rate of each OTUsub is equal to the reference rate level; modulating the N optical sub-channel transport units OTUsubs onto one or more optical carriers; and sending the one or more optical carriers onto a same fiber for transmission. The embodiments of the present invention map the client signal into a variable-rate container OTU-N and transmit the OTU-N by using the same fiber, so as to be adaptable to change of optical-layer spectrum bandwidths and accomplish optimal configuration of optical transport network bandwidth resources.
