Abstract

Reconfigurable Wavelength Add/Drop Modules (RWADMs) make up the cores of Optical Add/Drop Multiplexers (OADMs), the network elements which will enable next-generation optical networking.1–5 For the present work, we define the RWADM as a device comprising two logical input ports (IN and ADD) and two logical output ports (OUT and DROP), which has the ability to route selected wavelengths from either input port to either output port. The four logical ports of an WADM may be made up of more than one fiber each. For example, the DROP port may provide one fiber per wavelength or may use WDM to combine all dropped signals in a single fiber. Of course, a device with one multi-wavelength drop fiber can be converted into a device with many single-wavelength drop fibers (or vice versa) by appending a wavelength DMUX (MUX) to the drop fiber(s). For simplicity, this paper will concentrate on unidirectional WADMs which provide no wavelength conversion function.
