(ii)On the other hand, the wavelengths from input fiber links are demultiplexed by wavelength division demultiplexers. The demultiplexed optical signals are switched by thermo-optic switches and finally multiplexed onto the corresponding output fiber link.

(iii)The wavelengths carrying the optical signals for the node itself are dropped through add-drop multiplexers. These dropped signals are demultiplexed by SONET STS demultiplexer in order to provide optical signals to end-users.
