Optical fiber plastic coating anti-jitter fiber pay-off device and system

The invention discloses an optical fiber plastic coating anti-jitter fiber pay-off device. The optical fiber plastic coating anti-jitter fiber pay-off device comprises a pay-off rack and optical fiberreels. The optical fiber reels are mounted on the pay-off rack and rotate along with pay-off shafts to pay off optical fibers. Swing guide wheel assemblies are mounted on the pay-off rack. Each swingguide wheel assembly comprises a swing wheel bracket, an optical fiber guide wheel I, an optical fiber guide wheel II and a counter weight, wherein the optical fiber guide wheel I, the optical fiberguide wheel II and the counter weight are all mounted on the swing wheel bracket; the swing wheel bracket is mounted on the pay-off rack through bearings and can swing in the direction parallel to theaxial direction of the corresponding optical fiber reel; the connection lines of the centers of the optical fiber guide wheel I, the optical fiber guide wheel II and the counter weight form a triangle structure; and the optical
