Scientech2515 Laboratory for Mode Characteristics in Fiber Optics

When V<2.405, only single mode propagates in the waveguide and when V>2.405, the other modes propagate in the waveguide. Using this experimental, the student can easily differentiate between Single Mode and Multi Mode optical fiber cables.
