The general architecture of wavelength routing mesh network is as shown in:
ii. The different WDM network elements like Optical Line Terminals (OLT), Optical Add Drop Multiplexer (OADM), and Optical Cross Connects (OXC) etc. are shown in the architecture.
iii. OLTs are placed either at the end of links or in point-to-point configurations. OADMs are used at places where some fractions of the wavelengths need to be terminated and others need to be added and are typically in linear or ring topologies.
iv. OXCs enable mesh topologies and switching of wavelengths. Clients of these networks can be ATM, SONET, IP switches using the optical layer.
v. Network supports a variety of client types, such as IP routers, ATM switches, and SONET terminals and ADMs.
