by:FOT     2020-06-24

multifunctional experimental instrument of optical fiber types: GK - SYG item no: ZH8803 experimental purposes: 1. Understand the principle and characteristics of fiber optic microbend losses. Understand the transmission light intensity principle and characteristics of infinite attenuator. Learn and master the principle and method of use of optical fiber reflective sensor. 2. Understand & lsquo; Multi-function experimental apparatus of optical fiber & rsquo; The basic structure and principle, familiar with the various components, learn and master the correct method of use. Experimental apparatus: multi-function experimental apparatus of optical fiber, optical fiber reflective sensor, fiber optic equipment microbend sensor, transmission light intensity the infinite attenuator. The experiment content: optical fiber reflective sensor experiment 1. The fiber optic adapter of reflective optical fiber displacement sensor separately with multifunctional PIN and experimental apparatus of optical fiber LED interface is connected. , power supply is connected to the LED drive current transferred to the specified current. 2. Rotary screw micrometer, adjust the zero at a time. 1 mm and record of spiral micrometer reading, as well as the optical power readings. In the paper to make a displacement & ndash; The light intensity curve. Analyze the results. Fiber optic microbend sensor experiment 1. The microbend are connected to the multifunctional experimental instrument of optical fiber displacement sensor. 2. Connected to the power, arouses the spiral micrometer microbend displacement transducer, every 25 micron precession records at this time of light power value, at the same time record at this time of spiral micrometer in value. 3. Using data from curve, by using this curve analysis of the characteristics of fiber optic microbend loss. The transmission intensity infinite attenuation experiment 1. The transmission light intensity the infinite attenuator optical fiber adapter respectively with multifunctional PIN and experimental apparatus of optical fiber LED interface is connected, connect the power supply. 2. Turn the screw micrometer, observe the change of the optical power value, light power value of zui bigger as the displacement value of zero. Change the screw micrometer readings of a set of values, make the strength & ndash; The displacement curve. Analyze the results. Note: 1. Rotating spiral micrometer, quietly so as not to damage the equipment. 2. Appropriate use of the power and the connection path, disconnect the power supply first, otherwise it will damage to the equipment. 3. Work power zui shall not exceed 100 ma
