ABSTRACT:
A ferrule for optical fibers transmitting linearly polarized light capable of preventing deterioration and fluctuation of the extinction ratio. The ferrule incorporates at least two paths connecting a region in a vicinity of an end of a puncture for an optical fiber inside the flange portion with outside of the ferrule. These paths effectively enable the removal of air in such a region which could have caused an extraneous stress on the optical fiber resulting in deterioration of the extinction ratio. An optical fiber connector using this ferrule is also disclosed.
