Asia Communications and Photonics Conference (ACP),Guangzhou (China), on November 10-13, 2017. -- http://www.acpconf.org/ Unrepeatered transmission over SMF-28 fibre is investigated using Raman based amplification. Experiments and simulations demonstrate a transmission up to 200 km (41 dB) span length using 28Gbaud 64 QAM modulation employing digital back propagation in DSP. |
