Abstract This paper describes the design and implementation of wide-band Raman amplifiers for fiber-optic telecommunications systems.
Raman amplifiers are optical amplifiers based on Raman gain. They are often operated with light pulses, although continuous-wave operation is also possible.
The presented results open the way for the optimization of the 1310 nm Raman amplifier''s architecture and the enhanced utilization of Raman amplifiers in telecommunication systems.

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
In this example, which uses a Raman amplifi er with a net gain of 15 dB, a 1 dB connection loss can result in a 4 dB gain reduction, and a 2 dB connection loss increases the reduction in Raman gain to
Based on the stimulated Raman scattering (SRS) effect, a Raman amplifier uses a transmission fiber as the gain medium to transfer Raman pump power to C-band signals for amplification.
