Fiber optic cable anchoring device for use with fiber optic connectors and methods of using the same

Abstract

A fiber-optic connector housing (50) and cable (20, 20′) are attached together by an anchor (100, 200). The anchor includes a one-piece main body, a passage (110, 210), and an injection port (130, 230). The passage extends between first (102, 202) and second ends (104, 204) of the anchor. Strength members (40, 40′) of the cable are secured within the passage by a bonding material (90) and are thereby anchored to the connector housing. A proximal end (54) of the connector housing includes first (60) and second housing components (70) which capture the anchor. The passage passes through an optical fiber (30) of the cable. The passage includes first (120, 220), second (170, 270), and third portions (180, 280). The first portion radially positions the optical fiber. The second portion receives the bonding material and the strength members. The third portion receives a jacket (26, 26′) of the fiber optic cable. The injection port delivers the bonding material to the passage. The anchor may further include retention tabs (150) that fit within corresponding receivers (62, 72) within the connector.

         23 . A method for tuning an optical fiber within a fiber optic connector, the method comprising:
 providing an anchor including a passage;   inserting the optical fiber within the passage;   injecting bonding material within the passage thereby securing the optical fiber to the anchor at a first location of the optical fiber;   attaching the anchor within an interior of the fiber optic connector;   securing the optical fiber to a ferrule at a second location of the optical fiber;   rotating the ferrule to tune the ferrule relative to a connector housing of the fiber optic connector; and   rotationally holding the ferrule relative to the connector housing.   
     
     
         24 . The method of  claim 23 , further comprising inserting a strength member within the passage.
