                                        The industry anticipated that the SONET equipment makers
                                     would make reliable OC-192 (10-Gbps) systems or face stiff compe-
                                     tition from DWDM manufacturers, setting the stage for a new wave
                                     of competition.Actually, the SONET/SDH manufacturers jumped on
                                     the  WDM bandwagon with their own products. The major
                                     SONET/SDH and WDM systems manufacturers include the vendors
                                     shown in Table 7-2.
                                        Not everyone makes full systems; some make the components that
                                     go into a system. Still others create components and networking ele-
                                     ments in their catalog of offerings. The networking elements include
                                     the following:

                                       DWDM
                                       Optical amplifiers

                                       Add-drop multiplexers
                                       Optical cross-connects
                                       Optical gateways
                                       Optical network units

                                        The market has been in a feeding frenzy since the late 1990s and
                                     early 2000.
