Abstract
The present invention provides a non-physical contact (non-PC) visual fault locator (VFL) coupler that functions with fewer components and reduces handling, and without ferrule-to-ferrule contact, thereby reducing endface wear degradation and other problems. Specifically, the non-PC VFL coupler incorporates an alignment sleeve retainer that includes a connector stop, such that, when a field-installable fiber optic connector engages the alignment sleeve retainer of the non-PC VFL coupler, the endfaces of the ferrules of the non-PC VFL coupler and the field-installable fiber optic connector do not physically contact one another. Both 1.25 mm and 2.5 mm versions are contemplated, among others.
