<p>OPTICAL FIBER SPLICE AND METHODS OF MAKING A low loss optical fiber splice compises first and second assemblies each of which terminates an optical fiber. Each assembly includes a plug that has a passageway extending therethrough with a fiber positioned therein and having an end face extending at least to an end face of the plug. Each plug is received in a housing which has a flange at one end thereof and a bore to allow the fiber to extend therethrough. A collar and a spring are disposed about the housing with the spring engaging the housing and the collar. After a fiber is secured within each plug, the fiber cores are aligned with a curable optically matching adhesive material being injected between the end faces thereof. Then the adhesive material is cured to lock the fibers in an aligned position and to secure the plugs together. Afterwards, the collars are moved toward the housing bodies to compress the springs and the flanges are positioned in nests of a support frame. Then the collars are released whereupon the springs cause the collars to engage the support frame and secure the assemblies thereto. Also, the springs cause compressive forces to be imparted to the interface between the fibers to maintain the splice connection notwithstanding temperature cycling.</p> |
