摘要： An optical network is provided comprising an optical line termination coupled to a backbone network, in particular to an optical long haul network and a local exchange coupled to an optical access network, wherein said local exchange provides an optical connection between an optical network unit of a tree topology and the optical line termination, which is part of a ring topology. Also, a method is suggested for processing data in such an optical network.
