Abstract

An optical fiber including a plurality of embedded optical reflectors distributed periodically along the length of the fiber and a method of quantifying loss associated with an optical connector that is connected to optical fiber comprising a plurality of embedded optical reflectors distributed periodically along the length of the fiber. The method includes inserting an optical signal into the fiber through the optical connector; measuring a component of the optical signal reflected by at least one of the plurality of embedded optical reflectors, in which the component is received through the optical connector; calculating the difference in power level between the inserted and reflected signals; and quantifying, based on the calculated power level difference and the reflectivity of the embedded optical reflector, the loss associated with the optical connector.
