| Popis: | We report on a set of transmission experiments over seven different uncompensated fiber links carrying a 22-channel Nyquist-WDM signal comb based on polarization-multiplexed 16-quadrature amplitude modulation at R-S = 15.625 GBd (R-B = 125 Gb/s). The channel spacing was Delta f = 16 GHz. The experimental transmission performance was compared with analytical GN-model predictions showing a good agreement for all seven considered fiber types. Moreover, we used the experimental results for the validation of a fiber figure of merit based on the maximum reach, showing its effectiveness for approximate fiber performance prediction. Within the experimental tests, a maximum transmission distance of 3810 km at a bit error-rate of 1.5 x 10(-2) was achieved using a pure-silica-core fiber with 150 mu m(2) effective area, at a net spectral-efficiency-distance product of 24 700 (b . km)/(s . Hz), in a good agreement with the GN-model forecast. |
