Abstract
Management of future WDM networks will be fundamentally different from management of today's optical networks, because several signals at different wavelengths use the same fibre. It is essential for example that the signal wavelength can be identified with a simple and cost effective method. Therefore, pilot tones generated by amplitude modulation have been proposed for management and supervision of future WDM networks [1]. This raises the issue of interaction between the pilot tone and the network components.
