Abstract

A system for producing an optical fiber with inscribed grating array is described. The system comprises a fiber drawing apparatus for drawing an optical fiber, a writing system for inscribing a grating in the optical fiber during the drawing process of the optical fiber and a controller for controlling the driving of the writing system. According to the present invention the fiber drawing apparatus also comprises a fiber length and/or drawing detecting means for determining the fiber length and/or fiber drawing speed and/or a fiber drawing parameter during the drawing process. The controller thereby is configured for capturing information from the fiber length and/or drawing detecting means and for controlling the writing system based on the captured information captured from the fiber length and/or drawing detecting means.
