    摘要： Disclosed is a path-converted variable optical attenuator comprising: a transmitting fiber for launching an optical signal through a transmitting core; a receiving fiber for receiving the optical signal from the transmitting fiber through a receiving core; and a mirror having a reflector for obstructing the optical signal launched from the transmitting core of the transmitting fiber from proceeding into the receiving core of the receiving fiber, and being displaced in a direction allowing a portion of the optical signal of the transmitting fiber into the receiving fiber to attenuate the optical signal. An optical signal launched from the transmitting fiber to the receiving fiber is reflected to a separate path from paths of transmitting/receiving fibers so that attenuation may not vary according to wavelength.
