To increase the range of 1550 nm signal transmission, Raman amplifier can be used. We demonstrate the design and performance of 1550 nm Raman amplifier utilizing single pump laser 1450 nm. The both codirectional and counter-directional pumping Raman amplifier is compared. The maximum gain for counter pumping is 45.87 dB and minimum noise figure is 7 dB. The 1550 nm Raman amplifier gain is function of wavelength corresponds to 8–25 nm amplification bandwidth. The saturation input power of Raman amplifier is from 10 to 15 dBm as the pump wavelength increases from 200 to 800 mW in case of counter propagation pumping configuration. Parabolic pulse generation in standard single mode fiber is investigated for the fiber length 10–100 km.
