Abstract: A method for data processing in an optical network component includes filtering and optically equalizing an incoming optical signal and modulating the optically equalized signal. A corresponding optical network component is also provided.

Abstract: An optical splitter for a passive optical network for telecommunication signal transmission with an optical line terminal includes a wavelength selective optical electrical converter, an AC/DC splitter, an energy reservoir and optical switches, where the splitter comprises also a data transmission processing module by which the optical switches can be controlled according to data signals transmitted from the optical line terminal.

Abstract: The invention relates to a method to discover Optical Network Units (ONU) with different speed capabilities in an Ethernet Passive Optical Network (EPON) by an Optical Line Termination (OLT), where logical links in the network are identified by Logical Link IDs, and the OLT can transmit and receive data with 1 Gbit/s-speed (1 G) and 10 Gbit/s-speed (10 G), and the discovery process is handled in the OLT by a Multi Point Control Process (MPCP), which exchanges messages as Data Units (MPCPDU) with the ONUs. This is achieved by extending the standard MPCPDUs in a way, that backward compatability is assured.

Abstract: A method of data transmission in a network sharing a medium using a time division multiple access scheme in which a network unit receives data packets from a subnetwork, stores the data packets in a buffer until the arrival of a time-slot and sends the data packets over the shared medium in the upstream direction during the time-slot. Each of the data packets includes a payload and a header that includes a source address and a destination address. Storing the data packets in the buffer includes: determining the paired source and the destination addresses of a received packet; determining whether a composite frame having a composite frame header including the paired source and destination addresses already exists; if negative, creating the composite frame for the paired source and destination addresses; and aggregating the payload of the packet to a composite frame payload of the composite frame.
