The transmitter differentially encodes control information to generate a differentially coded signal; uses the differentially coded signal to modulate a signal sequence in which electricity concentrates at a particular frequency; applies time-division multiplexing on the modulated signal sequence and a primary signal in one of two polarized wave components, and applies time-division multiplexing on the other polarized wave components and the signal sequence itself; and polarization-multiplexes the both of the time-division multiplexed polarized waves into an optical signal; and transmits the optical signal to the receiver. The receiver polarization-demultiplexes the received optical signal to generate two polarized wave signals; extracts the signal sequence in which electricity concentrates at the particular frequency from the two polarized wave signals; and applies differential detection on the extracted signal sequence to demodulate the control information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical transmission/reception system, transmitter, receiver, and optical transmission/reception method","description":"An optical transmission and reception system includes a transmitter and receiver.
