Device for setting reference wavelength in optical channel monitoring module |
摘要 |
There is provided a reference wavelength setting device in an optical channel monitoring module having a variable filter, comprising: a reference wavelength provider with a light emitting device for outputting wide-band light upon receipt of a driving voltage; a light emitting device driver for switching the driving voltage to the light-emitting device upon the receipt of an emission-on signal; a fiber grating for reflecting only the light at the reference wavelengths from the wide-band light received from the light emitting device; an optical distributor for feeding the wide-band light received from the light-emitting device to the fiber grating and outputting the light at the reference wavelengths reflected by the fiber grating; and, an optical coupler for outputting the light received from the reference wavelength provider to the variable filter.
