WebBending loss measurement This project will deal with bending loss measurement techniques: •wrap on a mandrel technique •knot technique We will measure bending loss of a multimode fiber and a few singlemode fibers: •standard multimode fiber (62.5/125) •Corning SMF28, Ultrahigh NA fiber and Corning ClearCurve WebThe bend-induced optical loss in a monomode fiber has been studied as a continuous function of wavelength in the range 1.2–1.6 μm. The loss was observed to be an oscillatory function of wavelength. These observations were explained by using a model based on interference between the guided core mode in the fiber and a “whispering gallery” mode …
