Abstract:
1. An optical fiber transmission system, comprising: a terminal processing unit including a signal codec module, a terminal frame processing module, and a terminal electric/optical signal processing module, an optical transmission unit, and a switch unit with input and output thereof connected with the optical transmission unit, respectively, wherein the terminal processing unit, connecting with UE (user equipment), used for encapsulating and converting the signal of the UE to be transmitted into an optical signal and sending the optical signal to the optical transmission unit, as well as for de-encapsulating the signal from the optical transmission unit and sending the signal to the UE; wherein the optical transmission unit, connecting with the terminal processing unit and the switch unit respectively, used for multiplexing the encapsulated signal sent by the terminal processing unit and sending the multiplexed signal to the switch unit via an optical fiber; as well as for de-multiplexing the signal transmitted from the switch unit via an optical fiber and sending the de-multiplexed signal to the terminal processing unit; wherein the switch unit, connecting with the optical transmission unit, used for receiving the multiplexed signal from the optical transmission unit at the input side thereof, de-multiplexing the signal, determining the transmission destination of the signal according to the type of the signal and sending out the signal; and at the same time for multiplexing the signal that needs to be transmitted to the optical transmission unit at the output side thereof, converting the multiplexed signal to an optical signal and sending out the signal; wherein the signal codec module encodes various signals sent by UE and sends a digital signals to the terminal frame processing module; at the same time, decodes a digital signals sent by the terminal frame processing module and sends the decoded signals to the UE; wherein the terminal frame processing module receives the digital signals sent by the signal codec module, encapsulates the signals and sends the encapsulated signals to the terminal electric/optical signal processing module; meanwhile, de-encapsulates the electric signal sent by the terminal electric/optical signal processing module and then sends the signal to the signal codec module; and wherein the terminal electric/optical signal processing module converts the optical signal sent by an optical transmission unit into an electric signal and sends the electric signal to the terminal frame processing module; meanwhile, converts the electric signal sent by the terminal frame processing module into an optical signal and sends the optical signal to the optical transmission unit.
