摘要： 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.

摘要： Disclosed is a method for transmitting Ethernet service signals in a Wavelength Division Multiplexing (WDM) network, including: a Center receiving Ethernet service signals and transmitting the signals to a transmission channel; a receiving station receives the Ethernet service signals, performs a space-division cross operation upon the received signals, duplicates the signals into two copies, where one is locally downloaded while the other is returned to the transmission channel. Three devices for processing the Ethernet service signals in the WDM network are provided. With the present invention, the broadcast of the Ethernet service signals with large granularity is implemented, therefore decreasing the delay for broadcast the real-time services; besides, it is not necessary anymore to construct a overlapped network with three layers of devices, i.e. a WDM system, a Synchronous Digital Hierarchy (SDH) system and a data device, so the network structure is simplified and management is convenient.
