Abstract

An optical add-drop multiplexer having first and second routes includes: an optical cross connect (22, 22#1, 22#2) ; a first multiplexer (23W) optically coupled to a plurality of output ports of the optical cross connect; a second multiplexer (23E) optically coupled to a plurality of other output ports of the optical cross connect; a first wavelength selective switch (24W) to generate a first WDM optical signal including an optical signal output from the first multiplexer and to guide the first WDM optical signal to the first route; and a second wavelength selective switch (24E) to generate a second WDM optical signal including optical signal output from the second multiplexer and to guide the second WDM optical signal to the second route.
