▎ 摘　　要

NOVELTY - The method involves connecting a graphite chuck with an optical fiber transmission line, where the optical fiber transmission line is made of graphite (1). A common single-mode optical fiber (2) is connected with a chromatic dispersing part by utilizing multiple negative colors. The common single-mode optical fiber and the chromatic dispersion part are cascaded by a zero circuit. A graphite film (4) is arranged on a polishing surface of a polishing D-type optical fiber (3). An integrated dispersion compensation device made of graphite is arranged on a waveguide surface of the optical fiber. USE - Graphene based optical fiber dispersion compensating method for a communication system. ADVANTAGE - The method enables reducing insertion loss, saving raw material and saving producing cost. The method enables reducing dispersion compensation cost. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an optical fiber.
