We have comprehensively studied by numerical simulation high power transmission properties through single mode fiber for non-repeatered system application. We have clearly captured bit error rates (BERs) of digital coherent signal exhibit specific floor levels, depending on transmitter powers, due to fiber nonlinearity. If the maximum transmitter p...
In order to explore possible asymmetry of nonlinear degradation near zero dispersion, nonlinear propagation of single-channel 10 Gbps signal at and near zero dispersion wavelength of dispersion-shifted optical fiber (DSF) is comprehensively investigated in terms of signal power and wavelength as well as transmission distance. Inherent nonlinear deg...
The maximum input powers set by fiber nonlinearity are found approx.+19 dBm, +13.5 dBm and +8.5 dBm, respectively, for single-channel 120Gbps DP-QPSK, DP-16QAM and DP-64QAM formats in large-core and low-loss SMFs. These powers are also found to gradually decrease in logarithmic feature with the increase of the number of channels.
