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 opticalfibers 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 aplurality of transponder banks (TBK). The optical couplers (PC) are connected to some orall 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 ofthe 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), eachoptical couplers (PC) in said subset being connected to a different optical cross-connectunit (OXC1 through OXCs). In each transponder bank (TBK), for each of the signalsoutputted by the optical switches (PS) in that transponder bank (TBK), a signal of adesired wavelength is selected and supplied to a transponder.
