Abstract
A multi-fiber connector fiber-optic measurement device identifies a polarity type and measures an optical power of a multi-fiber connector fiber-optic patch cord. The device includes: a beam splitter that splits light from the multi-fiber connector fiber-optic patch cord into a plurality of lights; a first optical sensor that receives one of the lights split by the beam splitter and outputs a first signal according to the received light; a second optical sensor that receives another of the lights split by the beam splitter and outputs a second signal according to the received light; and a signal processor that calculates the optical power based on the first signal and identifies the polarity type based on the second signal.
