    摘要： A head-end circuit comprises first and second continuous light sources, first and second modulators. The first and the second continuous light sources provide first and second optical signals respectively corresponding to first wavelength and second wavelength, which is different from the first wavelength. The first modulator modulates the first optical signal based on first clock signal to generate an optical clock signal. The second modulator modulates the second optical signal based on downlink data to generate optical downlink data with the carrier of the second optical signal. The optical clock signal and the optical down link data are outputted to a remote antenna unit via first fiber path.

    摘要： An optical network and an optical signal modulation method thereof are provided. The optical network includes an optical fiber and a remote node (RN). The RN receives a continuous carrier wave from the optical fiber and modulates the continuous carrier wave to generate a first frequency offset carrier wave The frequency of the first frequency offset carrier wave is different from that of the continuous carrier wave. A first user device re-modulates and loads data to the first frequency offset carrier wave to generate a first upstream signal. The frequency of the first upstream signal is the same as that of the first frequency offset carrier wave. The RN inputs the first upstream signal into the optical fiber.

    摘要： An optical fiber communication system is provided, including a central office and an optical network unit. The central office generates a first downstream signal and a second downstream signal according to a radio frequency signal and a baseband signal, respectively. The optical network unit is coupled to the central office to receive the first downstream signal and the second downstream signal through a first fiber and a second fiber different from the first fiber, respectively, such that the optical network unit only modulates the second downstream signal to generate an upstream signal and then delivers the upstream signal to the central office through the first fiber, thereby decreasing signal Rayleigh backscatter noise.

Each of the ONUs has a third end and a fourth end both coupled to the optical fiber ring. Each of the ONUs receives the second signal from the third and the fourth end and transmits the first signal to the third and the fourth end. The ONUs connect to the OLT through the optical fiber ring so as to form a ring-based PON.
