Abstract: Disclosed is a monitoring system and method of monitoring optical-fiber drawing systems. The scattering monitor includes: a scattering monitor housing provided on a path drawing an optical fiber and having holes aligned on the upper and lower ends of the scattering monitor housing with the optical fiber passing there-through; a reflecting plate surrounding the optical fiber in the scattering monitor housing; a light condenser for converging light reflected from the reflecting plate; and, a light detector for detecting converged light and generating a corresponding electrical signal.

Abstract: Disclosed is a cooling apparatus used in a high-speed cooling of an optical fiber. The cooling apparatus includes: a cooling body extending along the longitudinal direction of the drawn optical fiber, wherein the cooling body consists of a left cooling body part and a right cooling body part, and wherein the cooling body is provided with a sealing cap so that a cooling gas is supplied into the cooling body through the sealing cap; and, at least one turbulence generator mounted within the cooling body to surround the drawn optical fiber, wherein the turbulence generator activates the molecular flow of the cooling gas supplied into the cooling body.

Abstract: Disclosed is a spinning device for low polarization mode dispersion. The spinning device for minimizing PMD(Polarization Mode Dispersion) of the drawn optical fiber in the optical fiber drawing process includes: a base plate arranged at a lower end of a drawing tower; a tilting spinning wheel mounted on the base plate for rotating along a first rotational shaft, for transferring a drawn optical fiber to a capstan, for periodically rotating along a second rotational shaft within a predetermined angle range at a perpendicular relation to the first rotational shaft, for applying a periodic twisting on the optical fiber using the tension of the drawn optical fiber with its outer periphery touched with the drawn optical fiber; and, a speed reducing unit connected to the second rotational shaft of the tilting spinning wheel for reducing the rotational speed of the wheel.

Abstract: Disclosed is a multi-line optical fiber drawing equipment, wherein at least two strands of optical fibers can be simultaneously drawn by the single draw tower, thereby maximizing an effectiveness of an installation space for a draw tower and the productivity in drawing the optical fiber. The optical fiber multi-line drawing equipment has at least two lines for drawing optical fibers from preforms. Each of the lines has a chuck, a furnace, a cooling unit, a coating unit, a curing unit, and a capstan, which are arranged in sequence in a draw tower. Processes for drawing optical fibers from preforms respectively along the lines are simultaneously performed.
