In the lumped case, the Raman amplifier consists of a sufficiently long spool of fiber along with the appropriate pump lasers in a package. In the distributed case, the fiber can simply be the fiber span

Raman amplification /ˈrɑːmən/ is a way of increasing the signal strength in an optical fiber. It is often used in a fiber that carries a signal for a long distance (such as in an undersea cable). Technically, it works by stimulating Raman scattering, in which a lower frequency ''signal'' photon induces inelastic scattering of a higher-frequency ''pump'' photon in an optical medium in the nonlinear regime. As a result, another ''signal'' photon is produced, with the surplus energy resonantly passed to the vibrational states of the

Raman amplifiers can be operated in very different wavelength regions, provided that a suitable pump source is available. The gain spectrum can be tailored by using different pump wavelengths

Network designers have several options to meet the need for higher transmission capacity. For instance, one obvious solution is to extend beyond the C-band into the L-band.

Since signal gain is distributed along the fiber, these amplifiers are called distributed, as opposed to traditional point or lumped amplifiers (such as Erbium-doped fiber amplifiers), in which signal power
