    摘要: An optical coupling system for wavelength-individual through-connection between wavelength-division multiplex (WDM) a plurality of input and output fibers with simultaneous possibility of wavelength conversion is provided. A respective optical splitter individually associated to an input fiber multiplies the WDM signal incoming on the appertaining input fiber into a.multidot.m WDM signals that are supplied to a.multidot.m tunable optical filters, wherein a is the plurality of output fibers and m is the plurality of wavelengths combined in a respective wavelength-division multiplex on an output fiber. Respectively, a plurality e of tunable filters connected to the plurality e of input fibers, combined at the output side via an optical combiner, lead to a wavelength converter that is connected to an input of a wavelength-division multiplexer preceding an output fiber.

    摘要: A communication system working according to an asynchronous transfer mode comprises ATM communication equipment units connected to one another, whereby a plurality of concentrator equipment units are connected to at least one of the ATM communication equipment units. The concentrator equipment units together with the corresponding ATM communication equipment units are thereby arranged in a ring line system. Within this ring line system, each of the concentrator equipment units is connected via a separate virtual path to, on the one hand, the corresponding ATM communication equipment unit and, on the other hand, to each of the remaining concentrator equipment units. A plurality of virtual connections having defined transmission capacities can be respectively conducted via the individual virtual paths. Particulars with respect to the transmission capacities already occupied for established virtual connections are kept separately for the individual virtual paths in the corresponding ATM communication equipment units and are updated with every set-up and clear-down of a virtual connection. According to the measure of these particulars, a new virtual connection is thereby allowed only given a transmission capacity on the respective, virtual path that is still adequate.
