CWDM

A CWDM (Coarse Wavelength Division Multiplexing) module is a device used in optical fiber communication systems to multiplex multiple optical signals onto a single fiber. It works by using different wavelengths of light (colors) to carry separate signals, which are then combined into a single fiber using the CWDM module. The module separates the different wavelengths of light at the receiving end, allowing each signal to be sent to its intended destination. CWDM Module is a low-cost method to maximize existing fiber by decreasing the channel spacing between wavelengths. CWDM has a lower cost per channel than dense WDM (DWDM) and no configuration is necessary. CWDM optical devices can increase bandwidth on existing fiber infrastructure and alleviate fiber exhaustion. CWDM optical devices are available as 4-channel, 8-channel or 16-channel mux/demux modules or as an add/drop module. Datasheet   Request more information/offer
