Abstract: A injection-molded connector for single-mode optical fibers includes two mating plugs having aligned fiber-receiving holes. To keep transmission losses in the connector at an acceptable level, the eccentricity of each hole relative to its plug profile must be maintained within a fraction of a micron. The mold utilized to form the plugs includes a dual-eccentric-cam adjustment mechanism that comprises nested conically shaped cams. In a method for fabricating such plugs, rotation of the cams serves to move a part of the mold that positions a hole-forming pin. By rotating this mechanism, the eccentricity of the fiber hole relative to the profile of the molded plug can be established and maintained within the required precision.

Abstract: An electrical terminating arrangement (100) serving as an interconnection juncture for joining central office equipment with outside plant facilities, an access point for testing and a protection provisioning point comprises connector apparatus (402), tie cabling (500) and protector apparatus (110) wherein the conventional stand-alone test field appearance is eliminated. Test access is provided directly through sockets (130) in front face (113) of protector apparatus (110), or indirectly to test lands through apertures (403) in protector device (400) inserted in sockets (130). Reliability is achieved by utilizing connector (170) to couple protector apparatus (110) to a mated connector on the outside plant stub cable. Installation complexity is reduced by employing snap-in details (190) as well as plug-in details.
