Abstract: Embodiments of this application disclose an upstream transmission resource allocation method and a related device. First, an OLT determines an upstream rate threshold of an ONU based on transmission quality information of upstream data sent by the ONU. The OLT further obtains a to-be-transmitted data amount of the ONU. Then, the OLT determines an upstream transmission timeslot of the ONU and an upstream transmission rate of the ONU. The upstream transmission rate of the ONU is less than or equal to the upstream rate threshold. The ONU is configured to send data of the to-be-transmitted data amount to the OLT in the upstream transmission timeslot based on the upstream transmission rate.

Abstract: An optical module includes a processing component and a plug component. The plug component includes a plurality of filters. The plurality of filters are connected to a plurality of secondary ports. The processing component includes a plurality of primary ports. The optical module is in a first connection status or a second connection status. When the optical module is respectively in the first connection status or the second connection status, a wavelength of a second service optical signal or a wavelength of a second local oscillator optical signal that are sent by the plurality of filters varies. When the optical module is in a same connection status, wavelengths of the second service optical signal and the second local oscillator optical signal that are sent by the plurality of filters are identical.

Abstract: A signal processing method is provided. Under the method, a first digital signal can be obtained by an optical transmitter. The first digital signal is a one-dimensional bipolar digital signal. A spectral compression and filtering can be performed by the optical transmitter on the first digital signal to generate a second digital signal. A frequency shift can be performed by the optical transmitter on the second digital signal such that a center location of a spectrum of the frequency-shifted second digital signal is at a frequency of 0.

Abstract: A first optical splitter splits a light source to obtain a first optical signal, a second optical signal, and a third optical signal. A first MZ modulator modulates the first optical signal to output a fourth optical signal. A second MZ modulator modulates the second optical signal to output a fifth optical signal. A first optical coupler couples the fourth optical signal and the fifth optical signal to output a sixth optical signal and a seventh optical signal. A power regulator and a phase shifter respectively perform power adjustment and phase shifting on the third optical signal to output an eighth optical signal. A second optical splitter splits the eighth optical signal into a ninth optical signal and a tenth optical signal. A second optical coupler combines the sixth optical signal and the ninth optical signal. A third optical coupler combines the seventh optical signal and the tenth optical signal.
