Abstract :
We measured the Raman gain efficiency for a dispersion compensating fiber (DCF) using a pump wavelength of 1240 nm and characterized the gain of a Raman amplifier in the O-band (1260-1360 nm) with a low pump power and a few kilometers of fiber. In addition, a spectral analysis of the fiber loss and Raman efficiency revealed that the increase in Raman gain efficiency towards short wavelengths can compensate for the increase in attenuation, with the obtainable gain for a 6-km fiber peaking at the O-band.
