Abstract

The optical channel design in this thesis looked at coherent optical fibre transmission methods for future optical networks. Traditional optical network architecture and future optical network concepts under development are initially discussed.The experimental study of the coherent receiver was carried out by doing a C-band spectral analysis and determining the power of the adjacent channels. In order to deliver PM-QPSK in a populated system, a solution that combined these two capabilities was developed.We were able to compare probabilistic and conventional deterministic design techniques by altering the intra-link optical power. According to testing, the transmission medium's non-linearity may lead to an optimal provisioning point. A three-parameter model effectively predicted optical power behaviour in a single-channel system. The correctness of the model was checked using WDM (Wavelength Division Multiplexed) technology.
