This paper presents experimental results for transmitting 40 Gb/s OTDM signal over in-line long fiber span using unidirectional backward Raman amplification. The investigation uses legacy dispersion-managed SMF-DCF configuration where remote Erbium amplification is used to compensate for the DCF spans losses. It is practically shown that the system performance improves significantly with more Raman pump power if we use an appropriate signal wavelength, Raman pump power and Erbium gain. As a result, successful unrepeatered transmission over 206 km SMF is achieved using 1545 nm signal wavelength, 1.58 W Raman power and unsaturated EDFA gains into the DCF spans. We believe that the results of such investigation can be useful for enhancing systems that still use legacy cables without the need for substantial alteration.
