Single mode Optical Fiber with reduced Polarization Mode Dispersion and Method for obtaining an optical fiber with reduced Polarization Mode and optical Telecommunications System

摘要

A method for determining at least one parameter of a function Alpha (Z) with periodic rotation period to be applied to an optical fiber along its length during a procedure d zAnd select the drawing, which comprises at least one parameter so that the formulas (1) where E1 is approx.0.05 and Y1 is the first of the three components (Y1, y2 Z) (Z),And in a periodic function (Z) and (Z) of period p so that they meet the following Equalities where LB is the length of the Optical Fiber is expected to shake and alpha '(Z) is the Derivative of theRotation function Alpha (Z) with respect to the length Z.The method is effective to substantially reduce PMD of Optical Fibres stretched while applying a rotation function as named above.
