Abstract

Baseband frequency response of graded-index multimode fibers depends on several dispersion factors; intermodal, material and construction dispersion. Generally, in graded-index multimode fibers, intermodel dispersion > material dispersion > contruction dispersion. Therefore, baseband frequency response depends mainly on intermodal dispersion. However, recently, the characteristics of graded-index multimode fibers have been improved so that material and construction dispersion are not negligible.
