Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for processing an optical network signal. The method includes: receiving an optical signal sent by an optical line terminal, where the optical signal includes two polarization components perpendicular to each other, and downlink data is modulated on one of the polarization components; dividing the optical signal into two signals, where each signal is the optical signal; demodulating the downlink data from one optical signal and performing, for the other optical signal, vertical polarization rotation processing and processing of modulating uplink data onto two polarization components of the optical signal; sending the other optical signal on which the vertical polarization rotation processing and the uplink data modulation processing are performed to the optical line terminal. With the embodiments of the present invention, signal processing load of the optical network unit and the optical line terminal can be lowered.

Abstract: An apparatus for despreading in an optical domain configured to split a received optical signal into a first optical signal and a second optical signal, perform phase deflection on the second optical signal, output a third optical signal, perform phase deflection on the first optical signal and the third optical signal, output a fourth optical signal and a fifth optical signal to a balanced receiver, and superimpose the fourth optical signal and the fifth optical signal to generate a first electrical signal. A multiplication operation in conventional code division multiple access (CDMA) despreading is transferred from an electrical domain to an optical domain such that a chip rate can be easily raised to 20 gigahertz (GHz) or even to 25 GHz, a maximum rate of 100 gigabits per second (Gbps) can be provided in a single wavelength, and a user requirement for high bandwidth can be met.
