The embodiments of the present disclosure disclose a method for processing optical signals, an optical module, an Optical Line Terminal (OLT) optical signal processing method and an OLT. The optical module includes two photoelectric transmitter and receiver units and a Wavelength Division Multiplexing (WDM) unit. Each photoelectric transmitter and receiver unit is configured to generate a downstream optical signal with a corresponding rate and wavelength according to an electric signal, and then output the downstream optical signal to the WDM unit; and receive an upstream optical signal outputted by the WDM unit with a rate and wavelength corresponding to a burst mode, and convert the upstream optical signal into the electric signal. The WDM unit is configured to, after receiving the downstream optical signals outputted by the two photoelectric transmitter and receiver units, perform WDM on the downstream optical signals, and then output the downstream optical signals; and receive the upstream optical signal, de-multiplex the upstream optical signal to obtain upstream optical signals with different rates and wavelengths, and output the upstream optical signals to the corresponding photoelectric transmitter and receiver units respectively. |
