The cost of an optical network in Wavelength-Division Multiplexing (WDM) networks can be reduced by using optical add/drop multiplexers (OADMs) which allow traffic to pass through without the need for an expensive optical-electro-optical (O-E-O) conversion. OADMs can be used to add/drop specific wavelengths as in the case of fixed OADMs (FOADMs), or more flexible as in reconfigurable OADMs (ROADMs)...
