Low-Noise Forward Pumping with Optimized Longitudinal Modes for Distributed Raman Amplifier in S+C+L-Band Transmission
We show the improvement of signal quality in <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathrm{S}+\mathrm{C}+\mathrm{L}$</tex>-band transmission using a low-beatnoise forward pumping. After 1200-km transmission, the measured signal-to-noise ratios were improved by more than <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$0.7 \text{dB}$</tex> compared to using a conventional technique.
