Using Nyquist pulse shaping and a 33-GHz spacing grid, we show that the 4D-32SP-16QAM format outperforms the Hybrid-QPSK/8QAM format over a transmission link made of standard single mode fiber.Rios-Muller, R.Renaudier, J.Bertran-Pardo, O....
Following modulations are considered: Phase Shift Keying (16PSK), Quadrature Amplitude Modulation (16QAM). The fuzzy approach to these modulations is presented. The BER and SER values are calculated using possibility theory. The results obtained by fuzzy noise model are compared with conventional ...
CoherentOptimalSupercomputerWe demonstrate, for the first time, the feasibility of using 40 Gb/s SP-16QAM and 80 Gb/s PDM-16QAM in an optimized cell switching supercomputer optical interconnect architecture based on semiconductor optical amplifiers as ON/OFF gates....
From our experimental results and numerical simulation, it can be concluded that 128-SP-QAM has significant BER improvement compared to PM-16QAM when optical signal to noise ratio (OSNR) is high. However, when it comes to low OSNR scenario such as transmission over a very long distance, 128...
