WDM is the current favorite multiplexing technology for long-haul communications in optical communication networks.  Wavelength-division multiplexing (WDM) is an approach that can exploit the huge opto-electronic bandwidth mismatch by requiring that each end-user's equipment operate only at electronic rate, but multiple WDM channels from different end-users may be multiplexed on the same fiber.
Under WDM, the optical transmission spectrum is carved up into a number of wavelength (frequency) bands, with each wavelength supporting a single communication channel operating at whatever rate one desires. By allowing multiple WDM channels to coexist on a single fiber, one can tap into the huge fiber bandwidth, with the corresponding challenges being the design and development of appropriate network architectures, protocols, and algorithms. Also, WDM devices are easier to implement since, generally, all components in a WDM device need to operate only at electronic speed; as a result, several WDM devices are available in the marketplace today, and more are emerging.
As a specialized WDM devices provider, we has been providing high performance CWDM/DWDM mux demux modules, CWDM OADM, DWDM OADM, WDM Filters, OEO converters, EDFA optical amplifiers and other compensation modules with lowest price.
