METHOD AND APPARATUS FOR DEMONSTRATION AND DETERMINATION OF MATERIAL DISPERSION IN OPTICAL FIBER

摘要

The present invention provides an apparatus (101) for demonstration and determination of material dispersion in an optical fiber comprising a plurality of light sources (102 a, 102 b) for providing a plurality of signals in form of pulse trains (! 10 a, 110 b), a coupling device (103) for coupling the plurality of signals in form of pulse trains, a de-coupling device ( 105) for decoupling the plurality of signals, in form of pulse trains, a plurality of detection units (106 a, 106 b) for detection of the decoupled plurality of signals, in form of pulse trains, a device (107) for determining the time delay between arrival of plurality of signals form of pulse trains, at the detection unit ( 106 a, 106 b), a device for displaying the plurality of signals in form of pulse trains (107), a microprocessor (108) and a plurality of optical fiber patch cords for connecting various above devices, wherein a length of optical fiber (104 b) is provided whose material dispersion is to be demonstrated and determined. A method of demonstrating and determining material dispersion of optical fiber using said a apparatus (101) is also disclosed.
