Title:
DEVICE FOR MEASURING OPTICAL WAVELENGTH
Document Type and Number:
WIPO Patent Application WO/2018/016759
Kind Code:
A1
Abstract:
The present invention relates to a device for measuring an optical wavelength and, more particularly, to a device for measuring an optical wavelength transmitted through an optical line of an optical communication network in which a plurality of optical wavelengths are muxed by a wavelength division multiplexing method. The disclosed device for measuring an optical wavelength may comprise: an optical input unit for receiving an optical signal including a plurality of optical wavelengths and outputting the optical signal as parallel light by means of a lens; a channel filter for filtering the optical signal outputted from the optical input unit; a rotating plate attached to the channel filter; a motor for rotating the rotating plate; a photodetector for converting the optical signal having passed through the channel filter into an electric signal and outputting the electric signal; a control unit for controlling a rotation angle of the motor; a signal processing unit for generating a rotation angle control signal for the control unit and extracting a light wavelength value on the basis of the rotation angle and the electric signal; and a display unit for displaying an optical wavelength value extracted from the signal processing circuit unit. According to the present invention, it is possible to check the quality and reliability of an optical communication system and facilitate the maintenance process of the optical communication network by providing accurate information on the wavelength value of the optical signal in a wavelength multiplexed optical communication system since it is possible to precisely measure the wavelength of the received optical signal and measure the output of the optical signal.
