Method of and device for the fine synchronization of ATM cells in optical ATM nodes.

摘要

Within an optical ATM node, an ATM cell to be synchronized is sent into a segment of pre-determined length of an optical fibre with a high time dispersion (FD), after having been associated, in a tunable wavelength converter (CL), to an optical carrier with a wavelength that is different from that with which the cell itself was received and such that, as an effect of the transit the fiber (FD), the cell reaches the input side of a switching element (Em1...Emh) of the node (NC) at a predetermined instant.
