Vedclass · Answer

(D) Optical fibers operate on the principle of total internal reflection. They are made of glass or plastic and are immune to electromagnetic interference because they transmit light signals rather than electrical signals. Therefore,the statement that optical fibers can be affected by external electromagnetic interference is false. All other statements regarding low transmission loss,homogeneous core with cladding,and varying refractive indices are correct characteristics of optical fibers.
