Patent ID: 7013086

Claim:
A method of feeding a plurality of signals from a plurality of users into an optical network, which comprises the following steps: providing an access node for optical networks with variable access wavelengths, including: a plurality of first optical conductors each disposed to connect a respective user device; at least one second optical conductor for connecting the access node to an optical network; and a plurality of light sources emitting unmodulated light signals at wavelengths of the optical network and connected to the first optical conductors for feeding the unmodulated light signals to the user devices such that the unmodulated light signals of the light sources can be modulated in the user devices; connecting a number of user devices each with a modulator to the access node; generating a number of light signals of different wavelength in the access node; extracting the light signals in unmodulated form from the access node and transmitting the unmodulated light signals to the user devices; modulating the light signals with user signals in the user devices to form modulated light signals; injecting the modulated light signals into the access node; generating wavelength division multiplex signals in the access node; and feeding the wavelength division multiplex signals into the optical network.
