40CH Mux Demux DWDM Passive Optical Network PON Rack-mount Patch Panel

DWDM (Dense Wavelength Division Multiplexer) technology is an extension of optical networking.

Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase the bandwidth of existing optical networks

DWDM devices (multiplexer, or Mux for short) combine the output from several optical transmitters for transmission across a single optical fiber. At the receiving end, another DWDM device (demultiplexer, or Demux for short) separates the combined optical signals and passes each channel to an optical receiver.

Passive DWDM network architecture begins with a transponder or transceiver accepting data inputs of various traffic types and protocols. This transponder performs the essential function of mapping input data onto an individual DWDM wavelength. Each individual wavelength is fed to an optical multiplexer (MUX) which filters and combines multiple wavelengths onto a single output port for transmission over the main/core/common DWDM fiber. At the receiving end wavelengths can then be separated to isolate the individual channels by using an optical demultiplexer (De-MUX), each channel is then routed to the appropriate client-side output through an additional wavelength matched transponder.

Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase the bandwidth of existing optical networks. The working principle of DWDM is to transmit multiple signals of different wavelengths at the same time on the same optical fiber. This technology creates multiple virtual optical fibers, increasing bandwidth on existing fiber optic backbones.
