FIELD: fiber-optic communication lines.
SUBSTANCE: in the method, next to main multi-mode optic fiber to communication line a compensating multi-mode optic fiber is placed, profile of which is selected dependently on profile of main multi-mode optic fiber, while depth, width and shape of axial space of profile of diffraction coefficient of compensating multi-mode optic fiber is selected so, that differential mode delay between groups of lower order modes and higher order modes in main and compensating multi-mode optic fibers had opposite signs.
EFFECT: broader functional capabilities.
