TEST METHOD FOR CHARACTERIZING AN OPTICAL FIBER LINK

Abstract:

There is provided a test method and system for characterizing an optical fiber link. At least one OTDR acquisition or at least one OLTS acquisition is performed on the optical fiber link. From the acquisition, a value of an excess insertion loss and/or an excess optical return loss associated with the optical fiber link under test is derived, i.e. in excess of a nominal value associated with a hypothetical optical fiber link having a length corresponding to the total length of the optical fiber link under test. A rating value associated with the optical fiber link under test can then be derived and displayed, e.g., as a five-star rating.
