PON Networks / CATV Optical Fiber Cwdm Multiplexer 16 Channels Mux Demux
* Coarse wavelength division multiplexing (CWDM) is a method of combining multiple signals on laser beams at various wavelengths for transmission along fiber optic cables, such that the number of channels is fewer than in dense wavelength division multiplexing (DWDM) but more than in standard wavelength division multiplexing (WDM).
* CWDM, cost-efficient transport in short-distance optical networks.
* CWDM typically has the capability to transport up to 18 channels (wavelengths) in the spectrum grid from 1270 nm to 1610 nm with 20 nm channel spacing. Each channel can operate at either 2.5, 4 or 10 gigabits per second (Gb/s).
* CWDM cannot be amplified as most of the channels are outside the operating window of the erbium-doped fiber amplifier (EDFA) used in DWDM systems. This results in a shorter overall system reach of approximately 100 kilometers (km). However, due to the broader channel spacing in CWDM, less sophisticated transceiver designs can be used, giving a cost advantage over DWDM systems.
