摘要 |
The invention relates to a modular optical network node, which divides the optical input signals into optical subbands, processed by a central element or by several central elements and which then recombines the optical subbands once again to form an optical output signal. Various functionalities, such as add-drop functionality, a drop and continue functionality, a multicast functionality, a broadcast functionality, a ring interconnect functionality, and a cross connect functionality, can be assigned to the central element or to the central elements of the modular optical network node. According to the assignment of a functionality, the modular optical network node can be used in networks having a different structure. |
