摘要： A strain-relief assembly for a field-installable fiber optic connector is disclosed, wherein the assembly includes a ferrule holder, an intermediate sleeve, and a crimp sleeve. The ferrule holder back section holds a buffered section of a fiber optic cable, while the ferrule holder front end holds a ferrule and a splice assembly. A stub fiber is held within the ferrule and the splice assembly so as to interface with a section of field optical fiber protruding from the buffered section. The intermediate sleeve engages and generally surrounds a portion of the ferrule holder back section and thus surrounds a portion of the buffered layer. An intermediate sleeve handler may be used to handle the intermediate sleeve and attached the intermediate sleeve to the ferrule holder back section. Stress-relief strands from the fiber optic cable are flared around the outer surface of the intermediate sleeve. A crimp sleeve is placed over the intermediate sleeve to hold the ends of the stress-relief strands in place. The crimp sleeve is then crimped, which fixes the strand ends in place and also fixes the intermediate sleeve in place on the ferrule back section.

摘要： A mechanical splice connector is shown and described for sequentially performing a splice actuation followed by a strain relief actuation by rotating a single, multiple-position cam member or multiple cam members from an unactuated position to a first actuated position and a second actuated position. The mechanical splice connector aligns and retains at least one stub optical fiber and the bare glass portion of at least one adjoining field optical fiber, as well as strain relieving a coated portion of the field optical fiber, or alternatively, a buffered portion of the field optical fiber. A method is also described for sequentially performing a splice actuation followed by a strain relief actuation, wherein the splice actuation is reversible prior to performing the strain relief actuation in the event that the optical continuity of the splice coupling is unacceptable, thereby avoiding potential damage to the field optical fiber or the connector.

摘要： A splice connector for verifying an acceptable splice termination includes a ferrule having a stub optical fiber, a ferrule holder for receiving the ferrule, opposed splice components within the ferrule holder for receiving and aligning the stub optical fiber and a field optical fiber, a cam member for engaging one of the splice components to terminate the field optical fiber, and means for viewing an amount of glow emanating from a termination area. In one embodiment, a splice component and the portion of the ferrule holder disposed between the splice component and the cam member are optically transmissive. The cam member has a first array of wells and a second array of wells for viewing the amount of glow before and after the field optical fiber is terminated. In another embodiment, the ferrule holder is opaque and has a view port, while the cam member has a first well having a first depth and a second well having a second depth.

摘要： Apparatus and methods for verifying an acceptable splice termination include propagating light energy into the stub optical fiber of a fiber optic connector, detecting and collecting the amount of optical power emanating from the stub optical fiber at a termination area of the connector, converting the optical power to an electrical signal proportional to the amount of collected optical power, and displaying the electrical signal on a feedback monitor, such as an optical power meter, an LCD bar graph, or an LED. An initial (i.e., reference) value is obtained with the field optical fiber not in physical contact with the stub optical fiber. A final (i.e., terminated) value is obtained with the field optical fiber in physical contact with the stub optical fiber and terminated to the connector. The final value is compared to the initial value to determine whether the change (i.e., difference) is sufficient. Alternatively, the final value is compared to a predetermined limit or threshold.
