Keywords: Optical fiber, coiled multimode fiber, helical pitch


               An experimental investigation behavior of speckle pattern of light at propagating in a coiled multimode optical fiber with a step refractive index. Discovered rotation of special pattern depended on the helical pitch, that is turn speckle pattern change when changing the helical pitch. It is   independent of the mode composition of the light propagating in the Optical fiber.
