Method and Apparatus for Transmitting and Receiving Client Signal in Optical Transport Network - A simplified explanation of the abstract
This abstract first appeared for US patent application 18173990 titled 'Method and Apparatus for Transmitting and Receiving Client Signal in Optical Transport Network
Simplified Explanation
The patent application describes a method and apparatus for transmitting and receiving a client signal in an optical transport network.
- The method involves mapping a received client signal into a variable-rate container called OTU-N, where the rate of OTU-N is N times higher than a preset reference rate.
- The variable-rate container OTU-N is then split into N optical sub-channel transport units called OTUsubs by column, where each OTUsub has a rate equal to the reference rate.
- The N optical sub-channel transport units OTUsubs are modulated onto one or more optical carriers.
- Finally, the one or more optical carriers are transmitted through a fiber.
Original Abstract Submitted
Embodiments of the present invention provide a method and an apparatus for transmitting and receiving a client signal in an optical transport network. In the transmission method, a received client signal is mapped into a variable-rate container OTU-N, wherein a rate of the OTU-N is N times as high as a preset reference rate; and then, the variable-rate container OTU-N is split into N optical sub-channel transport units OTUsubs by column, where a rate of each OTUsub equals to the reference rate; next, the N optical sub-channel transport units OTUsubs are modulated onto one or more optical carriers; at last, the one or more optical carriers is transmitted through a fiber.
