Dense Wavelength Division Multiplexing
The increased demands on fiber optic networks toward the end of the twentieth century spurred a concern of fiber exhaust. The backbone communications companies such as AT&T, Sprint, and WorldCom, sought an economical alternative to installing new fiber which resulted in the emergence of a new transmission technology called Dense Wavelength Division Multiplexing (DWDM). The development of this new technology enabled companies to meet the macro capacity demands placed …
