LOSSLESS TRANSMISSION OF 2PS PULSES OVER 45KM OF STANDARD FIBER AT 1.3-MU-M USING DISTRIBUTED RAMAN AMPLIFICATION

A 10 GHz, 2 ps pulse stream at 1.3 mu m is transmitted over a 45 km sp an of standard telecommunications fibre using distributed Raman amplif ication pumped with a compact and highly efficient fibre laser. When t he pulse source is tuned to the minimum dispersion wavelength of the f ibre, lossless, distortionless pulse transmission is demonstrated. By increasing the Raman pump power, a net gain of 8 dB over the span has been achieved, allowing the demonstration of nonlinear pulse compressi on.
