Abstract
A Raman pumping device () for amplifying a data optical signal in a fiber optic transmission system, comprising first and second ports () through which the data optical signal may respectively enter and exit the Raman pumping device (), a Raman pump source () for generating a Raman pump signal, and at least one combiner () for combining the Raman pump signal with the data optical signal. The Raman pumping device () allows for selectively combining the Raman pump signal generated by the same Raman pump source (), or at least parts of the same Raman pump source () codirectionally or counterdirectionally with the data optical signal.
