Abstract
An improved fiber optic connector including a selectively positioned attenuation barrel which forms part of a connector plug. As contrasted with the prior art construction which it replaces, structure is provided for preventing rotational movement of the attenuation barrel relative to an adapter body element of the connector in the form of a rotary locking ring, so that upon interconnection, any relative rotation between the abutted finished ends of a pair of fiber optic cores is prevented, thereby eliminating any possible abrasive action therebetween.
