Abstract
The Raman gain coefficient in G.652 (standard single mode) optical fibres is measured, based on the power transfer between a high intensity pump signal and on a counter-propagated broadband probe signal technique, complemented with spontaneous Raman spectroscopy. The Raman gain coefficient measured over a 90 nm wavelength range yield to a Raman gain slope and to a maximum value of the gain coefficient of 7.482 10<sup>-27 </sup>mW<sup>-1 </sup>Hz<sup>-1 </sup>and 0.540 10<sup>-27 </sup>m W<sup>-1</sup>, respectively. The values of 3.03 fs, 12.40 fs, 40.78 fs and 0.18 are experimentally obtained for the Raman time constant, first and second parameters of the Raman response function and fractional contribution of the delayed Raman response, respectively. These values are in agreement with previously reports and consistent with the obtained simulation results.
