Abstract
The present invention discloses an optical communication system, a sub-rate multiplexing/de-multiplexing apparatus and the method thereof such that the optical communication system could meet the demand of Metropolitan Area Network (MAN) communications using the existing optical fiber network. This optical communication system includes an optical transmitting module and an optical receiving module connected by optical fibers, wherein the optical transmitting module is used for converting the inputted electrical signals into optical signals and transferring the optical signals to the optical receiving module via optical fibers, and the optical receiving module is used for converting the received optical signals into electrical signals and outputting the electrical signals. In the optical signals transferred by optical fibers, the data transmission rate of at least one wavelength is about 5 Gb/s. One or multiple optical amplifiers may be incorporated as well between the optical transmitting module and the optical receiving module.
