Abstract: The invention relates to an optical fiber connector and to a related method for changing the polarity thereof. The connector comprises a ferrule, housing a plurality of terminations of optical fibers, and an inner housing arranged around the ferrule and comprising a rear portion and a front portion configured to be inserted into an optical fiber adapter. The front portion is releasably connected to the rear portion and comprises a frame, configured to surround an outer surface of the ferrule, and a key, extending from said frame along a longitudinal direction of the connector and configured to mate with a corresponding keyway provided in the optical fiber adapter, and The front portion is releasably connected to the rear portion by means of a first coupling member associated to the front portion cooperating with a second coupling member associated to the rear portion, in either one of a first orientation, in which the key extends along an upper wall of the inner housing, said first orientation corresponding to a first polarity of the connector with respect to the adapter, and a second orientation, in which the key extends along a lower wall of the inner housing, said second orientation corresponding to a second polarity of the connector with respect to the adapter.

Abstract: An optical cable includes a main body and a termination segment extending from an end of the main body. The main body includes middle portions of optical fibers. The termination segment includes end portions of the optical fibers and multi-fiber connectors attached to the end portions of the optical fibers. The multi-fiber connectors are staggered along a length of the termination segment.
