    摘要： An apparatus and method for measuring residual stress and photoelastic effect of an optical fiber is disclosed. The apparatus includes a rotating light diffuser for providing temporally averaged uniform image by restraining spatial coherence of light emitted from a light source to be completely scattered, a collecting lens for aligning the light passed through the rotating light diffuser in an optical fiber, a linear birefringence device for linearly controlling the polarization state of the aligned light input from the collecting lens, a condenser for condensing the light passed through the linear birefringence device on a place where the optical fiber is located, a fixed polarizer for transforming the polarization state of the light passed through the optical fiber to the intensity distribution by allowing the light emitted from the linear birefringence device to transmit the optical fiber, an objective lens for obtaining a magnified optical fiber image having the intensity distribution of the light transmitted the optical fiber, and a unit for measuring transmittance variation given to the optical fiber depending on locations.

    摘要： Disclosed is a system for drawing an optical fiber for controlling polarization mode dispersion. A furnace is provided for uniformly heating an optical fiber preform in the drawing system mounted to an optical fiber draw tower. The furnace comprises: (a) a main body; (b) a sub-body placed coaxially with the main body and having a diameter smaller than that of the main body; and (c) an upper gas feeding section over the main body, wherein the upper gas feeding section includes a first hollow rotary body having at least one slit in the inner surface thereof along the longitudinal direction of an optical fiber and at least one opening extended in the direction of the center, whereby a gas artificially/periodically creates non-contact polarization to the optical fiber by the first hollow rotary body. Effective non-contact control can be carried out about polarization mode dispersion of the optical fiber.
