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： An improved mechanical crimp provides increased fiber retention, while reducing the force required to form the crimp so that the crimp can be formed using a compact crimp mechanism disposed on a handheld installation tool. The crimp includes a deformable crimp tube and an optical fiber disposed within the crimp tube. A radial cross section of the crimp defines a plurality of alternating concave and convex outer surfaces. The crimp mechanism includes a base plate and a pair of crimp arms movably mounted on the base plate such that the crimp arms define a crimp area. The crimp mechanism further comprises an eccentric engaging at least one of the crimp arms and movably mounted on the base plate between a first position wherein the crimp arms are spaced apart at the crimp area and a second position wherein the crimp arms are not spaced apart at the crimp area.

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.

摘要： A field installable fiber optic connector includes a housing and a ferrule holder inserted from the rearward end of the housing. A spring element inserted into the front of the housing and a spring element retainer attached to the ferrule holder bias the ferrule holder forward. An optical fiber stub is disposed between opposed splice members and a field fiber is inserted between the splice members and guided by a groove into abutment with the end of the optical fiber stub. A cam disposed about the ferrule holder is movable to facilitate insertion of the field fiber and to clamp the field fiber and the optical fiber stub between the splice members. In one embodiment, a trigger is coupled to the housing. The trigger is disposed about and slides relative to the ferrule holder, thereby biasing the housing forward relative to the ferrule holder to aid in latching the connector.
