Abstract:
A method and a device for data processing in an optical network element are suggested, wherein the optical network element changes between a low-speed mode and a high-speed mode of data transmission.
Abstract:
A method of processing data for optical networks is provided, the method comprising the steps of mapping a plurality of input data streams into a plurality of output data streams and mapping the plurality output data streams into a plurality of optical carriers, wherein the mapping is realized by means of a look up table.
Abstract:
A method and a device for data processing in a passive optical network are provided, wherein a splitter comprises a reflective filter, wherein a first resource passes the splitter in uplink direction and wherein a second resource is reflected.
Abstract:
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.
Abstract:
A method and a device for data processing in an UDWDM network are provided, wherein one of at least two OLTs communicates with at least one ONU, wherein the at least one ONU is connected to a splitter that is connected to each of said at least two OLTs, wherein the at least two OLTs are active, and wherein the at least two OLTs provide protection switching and/or load sharing. Furthermore, a communication system is suggested comprising said device.
Abstract:
Described is a method for the transmission of the signals, comprising : - transmitting via a first transmission path (46) a first signal (V1) in a first frequency range and a second signal (V2) in a second frequency range, - the first frequency range is different from the second frequency range, - the first signal (V1) is the same as the second signal (V2).
