SYSTEM AND METHOD FOR TRANSMITTING OPTICAL SIGNAL OVER MULTIPLE CHANNELS

摘要

Since it is difficult to transmit optical signal over multiple channels with an improved received signal quality, better system margins, and reduced system outages, a method for transmitting optical signal over multiple channels according to an exemplary aspect of the invention includes: (a) firstly rearranging a plurality of tributaries of data to be transmitted in order to scramble the data among the plurality of tributaries; (b) transmitting optical signals modulated with rearranged data generated in step (a) over the multiple channels; (c) receiving the optical signals through the multiple channels; (d) demodulating the optical signals into a plurality of tributaries of the rearranged data; (e) secondly rearranging the plurality of tributaries of the rearranged data in order to recover the plurality of tributaries of data before step (a); and wherein, the number of tributaries of the rearranged data is equal to or more than two and is less than or equal to the number of the multiple channels.
