Fibre Raman amplifiers are currently being adopted in many long-haul systems due to their ability to offer longer amplification spans and high bandwidths. In this work, co- and counter pumping schemes have been analyzed experimentally. The pump and signal powers were maintained at 23 dBm and -10 dBm respectively throughout the experiment. Two fibre types, SMF-reach and SMF-RS each of length 25 km were considered. An on-off gain of 6.3 dB and 4.1 dB was achieved for co- and counter pumping schemes respectively for SMF-reach fibre. For a similar length of SMF-RS, an on-off gain of 4.8 dB and 3.9 dB for different pump configurations was obtained. Pump reflection power was noticed to vary inversely with gain. Therefore SMF-reach fibre is more suitable for Raman amplification in long-haul systems.
