摘要： Disclosed is a variable optical attenuator comprising: a transmitting fiber for transmitting light; a receiving fiber concentrically placed with said transmitting fiber for absorbing light; a shutter between said transmitting fiber and said receiving fiber for absorbing light to adjust optical transmittance; and an actuator for driving said shutter. The size and price of the optical attenuator is remarkably reduced compared to a conventional mechanical connector-type attenuator to provide an article excellent in competitive edge.
