WebMar 15, 2013 · DWDM fiber works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. In effect, one fiber is transformed into multiple virtual fibers. So, if you were to multiplex eight OC -48 signals into one fiber, you would increase the carrying capacity of that fiber from 2.5 Gb/s to 20 Gb/s. WebIt is also common to use a WDM coupler to add up two to three pump lasers with different center frequency. When using a different wavelength, pump power can be increased, and bandwidth is enlarged as well. By adjusting the ratio of these pump powers, Raman amplifier can achieve flat gain.
