One example method for sending a signal in optical communication includes generating, by an optical transmitter, multiple first subcarriers based on a bit stream. State of polarization (SOP) rotation is performed by the optical transmitter on at least one subcarrier in the multiple first subcarriers to generate multiple second subcarriers, wherein the multiple second subcarriers comprise multiple subcarriers each with a relative SOP rotation angle, and the relative SOP rotation angle is not zero and is not an integer multiple of 90 degrees. The multiple second subcarriers are modulated to an optical signal. The modulated optical signal is sent by the optical transmitter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for receiving and sending signal in optical communication, optical transceiver, and system","description":"The present disclosure provides example method for sending a signal in optical communication, an example optical transmitter, and an example optical communication system.
