ABSTRACT:
The present invention relates to an optical network with a number of nodes. Information is transmitted and, respectively, received in the nodes. The information is transmitted over a number of frequencies. Receiving and, respectively, transmitting of frequencies in the nodes is variable. The information is only converted to electrical signals in those nodes where the information is retrieved. Optical signals are amplified and distributed in the network via optical splitters and amplifiers. The capacity in the network can be redistributed depending on the capacity requirement in different parts of the network.
