Abstract

A key issue for the Operation & Maintenance (OAM) of an all-optical transport network is failure localisation in the network. The WDM supervision concept in the ACTS project PHOTON (Photonic Transport Overlay Network) achieves this by the introduction of defects and maintenance signals similar to existing transport networks. In the following this concept is explained.
