  • Optical connector and assembling method for the same
    Patent number: 7195400
    Abstract: An optical connector ferrule has an optical fiber containing hole reaching from the rear end surface near the end surface and a fine pore extending from the optical fiber accommodating hole to the end surface to be connected. A bare fiber of a polarization-maintaining optical fiber is inserted into the fine pore. Since the length of the fine pore is short, the influence of the uniformness of the adhesive in the fine pore is smaller, and therefore the stress distribution is maintained, resulting in stabilizing the polarization characteristics. A flange unit is attached to the ferrule after an optical fiber is inserted to the ferrule and fixed. Therefore the optical fiber is easily adjusted with respect to the housing in the circumferential direction around the axis, and optical fibers are connected by but joining with high accuracy.
