Abstract
There is provided a method, system and image capture device for determining a polarity of a multi-fiber cable link comprising a plurality of optical fiber links each connected between a first multi-fiber connector and a second multi-fiber connector, according to said polarity. Test light is injected into one or more of the optical fiber links via corresponding injection ports of the first multi-fiber connector, in accordance with a defined injection pattern; at least one polarity-testing image of the second multi-fiber connector is generated in which test light exiting at least one of the optical fiber links through one or more exit ports of the second multi-fiber connector is imaged as one or more spotlight spots in the polarity-testing image; and the polarity of the multi-fiber cable link is determined based on a pattern of said one or more spotlight spots in said polarity-testing image.
