  • Polarizer-equipped optical fiber ferrule, connector and connector adaptor
    Patent number: 6920255
    Abstract: The present invention provides a polarizer-attached optical fiber ferrule, a polarizer-attached optical fiber connector, and a polarized-attached optical fiber connector adapter for coupling a linear polarizer with one or more optical fibers without employing a lens. The polarizer-attached optical fiber connector 2 is equipped with an optical fiber 10, a ferrule 5 fitted on the periphery of the optical fiber 10 and equipped with a slit 16 reaching the optical fiber 10, and a linear polarizer 18 inserted into the slit 16 so that it crosses the optical fiber 10.
