Self-phase-modulation-based 2R regenerator including pulse compression and offset filtering for 426 Gbit/s RZ-33% transmission systems

Abstract: We report on the experimental and theoretical study of a self-phase-modulation-based regenerator at 42.6 Gbit/s with a return-to-zero 33% format. We point out some detrimental effects such as intrachannel interactions and Brillouin scattering. An efficient solution, relying on a self-phase-modulation-based pulse compressor in combination with the regenerator, is proposed to overcome these detrimental phenomena. The experimental demonstration shows the effectiveness of a wavelength-transparent regenerator at 42… Show more

“…We illustrate the results with a pulse train with a repetition rate set to 500 MHz, whilst the pulse width was kept constant to 2 ps. We confirmed similar trends to the ones described hereinafter are observed for pulse repetition rates up to 10 GHz, which prevent the occurrence of pulse-to-pulse interactions during nonlinear propagation in the fibre [33,34]. Firstly, we considered the effect of amplitude fluctuations in the one-bit pulses alone.…”

“…This can be partly attributed to the fact that in the anomalous dispersion regime of propagation, due to solitonic compression, the peak-power of the pulse increases, whereas in the normal regime, the peak power progressively decreases [25]. This reduction of the product power by length is also favorable in order to avoid the experimental problem of Brillouin backscattering which has been found critical in Mamyshev configurations [11,12].…”

[8][9][10][11][12][13] and theoretical (see [9,[12][13][14][15] and reference therein), have recently dealt with the possibilities of MR devices, much less studies have investigated the performances of soliton-based regenerators [1,[16][17][18][19][20].…”

“…As an important consequence, we can expect that no nonlinear interaction between adjacent pulses of a sequence will occur, so that detrimental patterning effects that have been observed in Mamyshev regenerators are avoided [11,14,15].…”
