Effect of modal noise on single mode fiber optic networks

Abstract Modal noise may arise in single mode fiber optic networks from the random coupling of the fundamental model LP01 and the higher order mode LP11. The higher mode LP11 is generated in the fiber optic link from imperfect connectors. A model for the modal noise generated in a single mode fiber optic network consisting of a number of connectors or splices is presented. The effect of modal noise on the link is discussed and expression for signal to noise ratio has been obtained. Suggestions for the reduction of modal noise are given.
