Abstract

The subject of the paper is the immediate and not so immediate future of the DWDM systems using direct TDM multiplexing for the individual wavelength channels. The following problems and questions have been tried to be addressed: a balance and competition between the electronic and optical bandwidths in WDM systems, importance of this competition now and in the future, major factors contributing to this competition, costs of the fast and dense WDM systems, the most important price generating factors in the WDM systems, etc. Some of the answers to these questions are very probably the following: now the best WDM systems work with spectral efficiencies of 0.2 bit/s/Hz for the trunk communications system solutions (5 THz of aggregated bandwidth) and well below 0.1 bit/s/Hz for the local communications; in the nearest decade the spectral efficiency of the WDM overcomes 0.5 bit/s/Hz and 50THz of the aggregated bandwidth (ten times the aggregated bandwidth used today).
