Abstract:
A wavelength to optical power converter used for monitoring the wavelength and the optical power in a fiber-optic communication system, comprising:an input fiber pigtail for inputting an optical wavelength signal; a cylinder for fixing said spiral fiber; a spiral fiber connected to said input fiber pigtail and wrapped around said fixed radius of said cylinder; an output fiber pigtail extended from said spiral fiber; and an optical detector connected to said output fiber pigtail for reading a signal from said output fiber pigtail to generate said optical power, wherein said fixed radius of said cylinder is smaller than 10 mm when maid optical wavelength signal is in the range between 750 nm and 1300 nm, and said fixed radius of said cylinder is more than 10 mm when said optical wavelength signal is in the range between 1300 nm and 1750 nm, and wherein said spiral fiber outputs said optical power in response to said optical wavelength signal, thereby performing a conversion from said wavelength into said optical power.
