  • Method for adjusting reception parameter of optical line terminal and optical line terminal
    Patent number: 10171894
    Abstract: This application discloses a method, including: determining a transmission rate of a to-perform-sending optical network unit (ONU); generating a reset signal before the to-perform-sending ONU sends an optical signal, where the reset signal is used to trigger the OLT to perform a reset operation; adjusting a signal characteristic of the reset signal according to the transmission rate, to generate an adjusted signal; extracting a signal characteristic of the adjusted signal, and generating a first signal and a second signal according to the signal characteristic of the adjusted signal, where the first signal indicates the reset signal, and the second signal indicates the transmission rate of the to-perform-sending ONU; performing the reset operation according to the first signal; and after the reset operation is completed, adjusting the reception parameter of the optical line terminal OLT according to the second signal.
