PHOTON is one of the ACTS projects which aims at the development of selected concepts for the future transport network and at the implementation of its key functionalities in a field trial for demonstration of the feasibility and validation of the networking ideas. Within the project PHOTON the design of the all-optical nodes for the optical transport network will be demonstrated and verified in the PHOTON field trial called PHOTONET. In PHOTONET, a border crossing star network between Munich and Vienna via Passau will be implemented demonstrating transmission and cross- connection of optical frequency division multiplexed signals over already installed single mode fiber, spanning a distance of 524 km. The optical cross connect (OCC) builds the inner node of the network, connecting several FDM links (multichannel ports) and a number of single channel ports. The latter ones are used for adding local add/drop functionality to the OCC. The principal functions of an OCC are to perform all-optical cross-connecting, optical signal supervision, optical signal regeneration and add/drop functionality. The optical terminal multiplexer (OTMX) builds the interface between the client network and the optical transport network. The basic functions of the OTMX are the provision of the interface to the existing transport networks and to the novel leased optical channel service. The OCC and OTMX architectures are modular, so that any new requests for improvement of their functionality (as frequency conversion or fiber protection switching) can be easily achieved.
