In this paper se compare the performance of a 12Gb/s transmission in a PON using different types of digital modulations with FEC (Forward Enhanced Control) and differential codification. In order to define an optimal modulation scheme for this PON, some comparisons were made between 16QAM (16-level Quadrature Amplitude Modulation) and PS-QPSK (Polarization-Switched Quadrature Phase-Shift Keying). We defined an objective BER of 10−3 given that it is the FEC limit. The previously described transmission system was simulated using the VPI-Photonics™ software, which allows recreating realistic optical networks environments. Results show that PS-QPSK performs better than 16QAM modulation from the BER perspective. |
