摘要： A method for making an optical fiber preform having an ultimately low PMD (Polarization Mode Dispersion) through improvement of ovality is provided. This method has several collapse steps for collapsing an optical fiber preform having a clad/core deposition layer formed in a preform tube in which a rate of collapse is 0.01-0.06 mm/min at each collapsing step. By using this method, ovality and PMD of the optical fiber preform may be improved.

摘要： A method of applying spin to a coated optical fiber to be rotated on its longitudinal axis so that the optical fiber has an ultra-low PMD (Polarization Mode Dispersion) includes the steps of: guiding the coated optical fiber so as not to be deviated from a certain range off a drawing axis at a lower end of an optical fiber coating point; giving torque to the optical fiber by contacting the coated optical fiber with a driving roller which vibrates on the center of an axis substantially parallel to a drawing direction at a lower end of the guiding point; and adjusting an amplitude (A) of the driving roller and a distance (l) between the guiding point and the vibrating point so as to control an angle (θ) between the vibrating optical and the drawing axis. This makes it possible to control a spin rate (spins/m) of the optical fiber generated by rotation.

摘要： Disclosed is a tube for installing an optical fiber unit having lubricous surface, which is installed in a communication pipe. The tube for installation includes an inner layer having lubricant components to decrease friction against an optical fiber unit, and an outer layer provided around the inner layer and composed of polymer having a lower friction coefficient than polyethylene so as to decrease friction when the tube is installed in the communication pipe. The tube is easier to install than the conventional one due to decreased friction against the communication pipe.
