First Claim
Patent Images
1. A method for automated node-level fiber testing and evaluation, the method comprising:
- determining, through communication to a node, a listing of equipment and a fibre trail associated with the node, wherein the node comprises a reconfigurable optical add/drop multiplexer with a plurality of modules associated with the fibre trail;
determining the fibre trail can be safely tested based on identifying a port trail of each active wavelength utilizing the listing of equipment, wherein the fibre trail is safely tested if it is one of i) carrying active wavelengths which are not subject to interference in a course of testing and ii) dark being connected but not carrying active wavelengths; and
causing a test of the fibre trail using one or more light sources in the plurality of modules to determine continuity and an amount of measured fiber loss of intra and inter-node fiber connections associated with the fibre trail utilizing Amplified Spontaneous Emission (ASE).
