OADM Based on WDM Technology – A Way to the Development of Optical Network

As it is known to all, optical multiplexers are components specifically designed for wavelength division multiplexing (WDM) systems. The optical multiplexer couples two or more wavelengths into the same fiber, while the optical demultiplexer separates a multiplicity of wavelengths in a fiber and directs them to many fibers (see figure 1). If a multiplexer is ...

Different Technologies Used in DWDM Multiplexer

Dense wavelength division multiplexing (DWDM) is an advancing fiber-optic transmission technology which combines multiple optical channels at different light wavelengths and then transmits them over the same optical fiber. Theoretically, the DWDM technology can multiplex hundreds and even thousands of separate wavelengths into a single optical fiber. To achieve this goal, the DWDM multiplexer is one of ...
