Normal WDM (sometimes called BWDM) uses the two normal wavelengths 1310 and 1550 nm on one fiber. Dense WDM (DWDM) uses the C-Band (1530 nm-1565 nm) transmission window but with denser channel. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i. At the receiving. WDM is an abbreviation for Wavelength-Division Multiplexing, and is now one of the most widely used technology for high-capacity optical communication systems. Figure 1 schematically shows a typical WDM transmission system.
