Abstract

The multichannel fiber optic connector, adapter, and contact retention method is disclosed. The connector includes a load carousel which enables handling, locating, retention, and, where needed, spring-loading of the plurality of single-fiber fiber optic ferrules supported within the connector, and the connector itself provides for independent axial and radial alignment of the fiber optic contacts. The adapter includes a plurality of optical alignment sleeves, and mating interfaces for two different connector types on differing sides of the adapter, wherein the fiber count of one connector type is an integral multiple of the fiber count of the other connector type, and wherein the contact pattern of the first connector type is repeated the same integral number of times within the contact pattern of the second connector type. The contact retention method is achieved by means of a load carousel, which provides a devoted location for each of the plurality of single-fiber fiber optic ferrules it supports, and which, when necessary, provides an independent spring member for each ferrule, and which allows both terminated and unterminated ferrules to be assembled therein, and which furthe…
