FIELD: physics, communication.
SUBSTANCE: invention is related to fiber optic communication equipment and may be used to increase pass band of multimode fiber optic transmission line. Method for increase of pass band of multimode fiber optic transmission line consists in the fact that in gradient multimode optic fiber, core material is alloyed with non-linear additive, and at that core material is alloyed only within the limits of the main mode spot.
EFFECT: increase of pass band of multimode fiber optic transmission line, reduction of optical power threshold required for formation of non-linear mode in fiber, reduction of differential mode delay of multimode optical fiber with notch in axis, expansion of application field.
