Filter Wavelength Division Multiplexer
Pictures and Schematic Diagram
The thin-film filter based wavelength division multiplexer is utilized to combine and separate optical signals in an FTTP network. The use of WDM technology expands the capacity of single fiber, as it allows multiple light signals to be conveyed at the same, in parallel and over single fiber. Thanks to WDM technology, two-way communications become more manageable and efficient. The filter wavelength division multiplexer is widely used in optical network upgrade and expansion.
