Method and the system of the multiplexer channel optical transmission which utilizes coherence division multiplexing with optical filtering

摘要

(57) Abstract Topic Through the identical optical fiber, method and the system of coherence division multiplexing (CDM) in order to transmit the plural light information are offered. Solutions On the basis of the optical selection and filtering of each CDM light information, making use with of optical path agreement interference method and the phase modulation of part coherent light, the noise which it is related to the other non-selective CDM light information is decreased.
