Optical receiving apparatus and optical communication system using same

摘要

An optical receiving apparatus for reducing crosstalk in a WDM communication system is disclosed. The receiving device includes a wavelength division de-multiplexer for receiving and de-multiplexing a first multiplexed optical signal and a second multiplexed optical signal, a first receiver for photo-electrically converting the first optical signal input from the wavelength division de-multiplexer into a first data signal, a second receiver for photo-electrically converting the second optical signal input from the wavelength division de-multiplexer and dividing the photo-electrically converted signal into a first division signal and a second division signal according to power and a compensator for inversing the second division signal and combining the inversed signal with the first data signal, thereby generating a signal compensating for crosstalk.
