Abstract: PURPOSE: A wavelength-shifted bidirectional wavelength division multiplexing optical network is provided to fundamentally block signal distortion due to Rayleigh backscattering which can be generated when using one optical line and the reflected light of optical components, thereby providing a high-quality optical network. CONSTITUTION: A wavelength-shifted bidirectional wavelength division multiplexing (WDM) optical network comprises an optical line terminal (OLT) (310) and a remote node (RN) (330). A first optical circulator (315) of the OLT transmits a downlink (DL) WDM optical signal wavelength-multiplexed by a first standard-type wavelength multiplexing/demultiplexing unit (313) through an optical fiber (320) for optical line or transmits a wavelength-multiplexed uplink (UL) WDM optical signal transmitted through the optical fiber to a first wavelength shift-type wavelength multiplexing/demultiplexing unit (314). A second optical circulator (331) of the RN transmits an UL WDM optical signal wavelength-multiplexed by a second wavelength shift-type wavelength multiplexing/demultiplexing unit (332) through the optical fiber or transmits a wavelength-multiplexed DL WDM optical signal transmitted through the optical fiber to a second standard-type wavelength multiplexing/demultiplexing unit (333).

Abstract: PURPOSE: A tunable laser module is provided to improve an output characteristic by using two arms of a Mach-Zehnder light modulator for two output terminals. CONSTITUTION: A tunable laser module comprises a light gain area unit (401), a light distribution unit (402), a light coupling unit (407), and a light amplifying unit (408). The light distribution unit separates a light signal which is output from a light gain area unit. Two comb reflection units (403, 404) reflect one part of the light signal which is separated by the light distribution unit, and transmits the other part of the separated signal. The light coupling unit combines light signals whose phases are changed by two phase units (405, 406). The light amplifying unit amplifies the light signal which is combined by the light coupling unit. The light gain area unit oscillates laser by totally reflecting the light signal which are reflected by the two comb reflection unit.
