Abstract
A signal processing method, an optical receiver and optical network system is provided. The method includes: receiving a first optical signal sent by an optical network unit, generating a second optical signal and modulating a phase of the second optical signal, obtaining at least one path of electrical signals after the first optical signal and the second optical signal separately undergo polarization splitting, frequency mixing, and optical-electrical conversion, outputting a third electrical signal after performing operation processing on the at least one path of electrical signals, and restoring a data signal according to the third electrical signal and performing sending. The embodiments example benefits are greatly reducing complexity of system implementation and maximally reducing a system upgrade cost and an optical power loss.
