Abstract
A non-contact method of measuring an insertion loss of a device-under-test (DUT) connector is disclosed. The method includes arranging the DUT connector and a reference connector so that their respective ferrule ends are confronting and spaced apart. The method also includes moving the reference and DUT connectors closer together while measuring the insertion loss and while also actively maintaining alignment of the first and second ferrules using a position measurement system. The insertion loss for the DUT connector is obtained by estimating a value for the insertion loss at a position where the end faces of the reference and connector ferrules would come into contact.
