The aim is to find a costeffective very high speed transport solution. Numerical investigation was performed using Monte Carlo simulations. The obtained results indicate that some modulation formats can be operated at 100Gbps in optical communication systems with low implementation effort and high spectral efficiency. }, journal = {International Journal of Electronics and Communication Engineering}, volume = {7}, number = {8}, year = {2013}, pages = {1060 - 1066}, ee = {https://publications.waset.org/pdf/16151}, url = {https://publications.waset.org/vol/80}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 80, 2013}, }
