Abstract
An apparatus for determining optical fiber array polarity is disclosed. The apparatus may be used to determine optical signal loss or intensity. An adapter may be used to couple the apparatus to a variety of optical fiber connectors. The apparatus includes a position sensing detector and processing circuitry. The position sensing detector includes a sensor that receives optical signals and electrodes that output respective output signals in response to receipt of an optical signal. The processing circuitry receives the output signals and identifies locations at which the optical signals were incident on the sensor. The processing circuitry also determines the receiving position in the optical array of an optical fiber and a polarity of the optical array based on the receiving position and a corresponding transmitting position. The processing circuitry may determine an intensity or loss of the optical signal based on an aggregate of the output signals.
