摘要： This invention substantially reduces the hardware complexity of an optical add-drop multiplexer, in an optical node, that can drop desired signals from input optical fibers or add desired signals to output optical fibers leading away from an optical cross-connect. This invention is provided with a plurality of 1*20s optical couplers (PC) and a plurality of transponder banks (TBK). The optical couplers (PC) are connected to some or all of s sets of input optical fibers (Fi1 through Fi(n-2)), said sets being connected, respectively, to a plurality of optical cross-connect units (OXC1 through OXCs). Each of the transponder banks (TBK) has a set of s* 1 optical switches (PS), each of which receives, and selects one of, signals outputted from a subset of the optical couplers (PC), each optical couplers (PC) in said subset being connected to a different optical cross-connect unit (OXC1 through OXCs). In each transponder bank (TBK), for each of the signals outputted by the optical switches (PS) in that transponder bank (TBK), a signal of a desired wavelength is selected and supplied to a transponder.

摘要： A method for automatic topology discovery implemented in a wavelength division multiplexing (WDM) network is disclosed. The WDM network contains a number of wavelength switching devices, and the method starts with selecting an unassigned wavelength between a pair of wavelength switching devices. For a first port of a first wavelength switching device, a pass through state is configured between the first port and a coupling port of the first wavelength switching device, and a first probing signal is sent at the unassigned wavelength to the first wavelength switching device. The method continues with detecting iteratively the first probing signal at the unassigned wavelength through each of a set of ports of a second wavelength switching device during a time period, and recording a connection between the first port of the first wavelength switching device and a port of the second wavelength switching devices when the first probing signal is detected.
