After 10 km SMF-28 transmission, in order to obtain the optimal output, which requires that the input power into the PD cannot be too low, a following erbium-doped fiber amplifier (EDFA) was utilized to compensate the attenuation of the fiber.
One of the most usable in the contemporary submarine and long-haul terrestrial networks is the distributed Raman amplifiers (DRAs) used stimulated Raman scattering (SRS) effect, which has many advantages: stimulated Raman amplification can occur in any fiber at any signal wavelength by proper choice of the pump wavelength; the Raman gain process is very fast and the effective noise figure (NF) of DRA is smaller than the one of Erbium-doped fiber amplifier (EDFA) and/or the semiconductor optical amplifier [2,3].
As the channel count increases, more channels have to be confined to the erbium-doped fiber amplifier gain band by reducing the channel spacing.
