Abstract

A wavelength-power converter is applicable to monitor and protect wavelength and power in an optical fiber communication system. The converter consists of an input fiber to receive an input light of a wavelength, a coiled optical fiber connected to the input fiber, a cylinder to which the coiled optical fiber is attached, an output fiber extending from the coiled optical fiber on the cylinder, and a light detector connected to the output fiber to detect signal and output optical power. Owing to the bending characteristics of the coiled optical fiber, light of different wavelengths generates different output power and conversion between wavelength and power is thus achieved.

After adjusting the appropriate parameters of the sensor, it is incorporated into the reaction using the existing material loss of the optical fiber and added to it It can be different: when a long optical signal is input, there will be a corresponding change in the output value characteristics. A new type of optical fiber winding wavelength-power conversion system can be set up. Please refer to the second figure for the wavelength-power conversion of this case. The principle is shown. The combination of the so-called appropriate parameter adjustment of the sensor includes the number of turns of Qufeng, the specifications of the optical fiber, etc. The specifications of the optical fiber are light: volume tolerance, that is, the loss of space to different degrees.
