Abstract
An insertion loss determination system contactlessly and automatically determines an insertion loss of an optical fiber connector having a domed combination of an optical fiber and a surrounding support ferrule. The system is suitable for a fully automated connector assembly line. In structure, the system comprises (a) a core-to-ferrule eccentricity (CFE) inspection system configured to determine a CFE parameter corresponding with an offset between a fiber center and a ferrule center; (b) a fiber light intensity tester (FLIT) configured to determine a FLIT parameter corresponding with an amount of a reference light that fails to pass through the fiber; and (c) an insertion loss evaluation system configured to determine an insertion loss of the connector based upon the parameters. The evaluation system may further be configured to identify an insertion loss class, for example, very good, good, or bad, based upon the insertion loss.
