Abstract: A test apparatus and method for testing passive optical networks is provided. The test apparatus includes an optical circuit having an optical coupler for splitting off a portion of optical traffic. During testing of a passive optical network, the optical circuit is coupled into an optical path of the passive optical network. A bit stream corresponding to an activating procedure is captured and analyzed to extract identification information of the module that sent the bit stream.

Abstract: A test instrument can be coupled to a test point in a passive optical network to measure optical signals transmitted between an optical line terminal and an optical network unit in the optical network. The test instrument can capture an identifier of the ONU from downstream signals sent from the OLT to the ONU.
