Since dense wavelength division multiplexing exists
Dense wavelength-division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of EDFAs, which are effective for wavelengths between approximately 1525–1565 nm (C band), or 1570–1610 nm (L band). Today, DWDM is a crucial component of optical networks because it maximizes the use of installed fiber cable and allows new services to be quickly and easily provisioned. Dense Wavelength Division Multiplexing or DWDM is the method which allows multiple wavelengths to be brought to a single-mode fiber, consequently growing the potential of that particular transmission route by using a factor which is equal to the total number of wavelengths that one has added during. Dense wavelength division multiplexing (DWDM) is a fiber-optic transmission technique that employs light wavelengths to transmit data parallel-by-bit or serial-by-character. It is the primary method used to maximize the information carrying potential of the world's extensive fiber optic cable infrastructure.
