| Abstract: | The optical-fiber communications regards light wave as carrier frequency, is regarded light-transmitting fiber as and transmitted a kind of communication way of media. The optical-fiber communications must use swift and violent development in short 20 years recently, it has transmit bandwidth, communication capacity heavy frequently, signal loss conspicuous advantage low,free from interruption by electromagnetic wave to have. This text has explained the opticalfiber communications transmission means implementing scheme standing in the team control floodgate, comparatively introduce systematic characteristic and function in detail,hope to play a role in drawing lessons from for the similar project. |
