An apparatus and a method for estimating optical insertion loss of a fiber optic jumper cable are disclosed. Estimation of the insertion loss is accomplished without physically contacting an optical connection portion of the ferrule end face of the connector. In one embodiment, the apparatus and method use pattern matching to compare an optical fiber core of a reference jumper cable with an optical fiber core of a jumper cable being tested. Then, the relative signals for each pattern are compared and used for estimating the optical insertion loss using an appropriate algorithm. Additionally, the apparatus and method may include other inspection techniques such as surface and/or geometry inspection.
