1. A method for testing if an optical ring network including nodes operates according to network specifications, the method
comprising the steps of:
verifying a node installation using an internal Amplified Spontaneous Emission (ASE) light source inherently present in the
optical network for measuring losses inside the node, and comparing measured losses with losses provided by the network specifications;
preparing for node commissioning by obtaining target values from the network specifications;
commissioning nodes using the internal ASE light source for measuring losses inside and between the nodes; and
checking commissioning of the nodes by reconciling loss and gain of the optical ring network with the network specifications.
