Dense Wavelength Division Multiplexing (DWDM) is anoptical multiplexingtechnology used to increase bandwidth overexisting fiber networks.DWDM works by combining and transmittingmultiple signals simultaneouslyat different wavelengths on the samefiber. The technology createsmultiple virtual fibers, thus multiplyingthe capacity of the physicalmedium. DWDM provides ultimate scalability and reach for fiber networks.Withoutthe capacity and reach of DWDM systems, most Web…
