Abstract
A Raman amplifier for use in an optical fiber communication system with dispersion compensation has a first order Raman pump source and a second order Raman pump source both coupled to the input ports of a four-port optical coupler having two input ports and two output ports. One output port is connected to an optical fiber length to inject a pump light signal into the fiber length for second-order Raman amplification and the other output port is connected to a dispersion compensating fiber.
