40-Gb/s 2-Channel all-optical 3R regeneration with simultaneous wavelength conversion has been realised by a fiber parametric amplifier(FPA) with the data signal to be regenerated as the pump,eliminating the unequal suppression of noise between bit0 and bit1. Signal to noise ratio is improved respectively from 2.7, 2.4 to 4.9, 5.2.
We propose a novel scheme for simultaneous retiming and reshaping of two wavelength-division-multiplexing channels using two independent phase clock pump and polarization multiplexing in fiber-optic parametric amplification, with the benefits of suppressing the interchannel cross-phase-modulation effect induced by the clock pumps and four-wave-mixing crosstalk. Operation of two 10-Gb/s channels is...
All-optical regenerator based on single pump fiber-optic parametric amplifier (FOPA) is demostrated experimentally. The input signal wavelength range of the regenerator is investigated, and its permance is further assessed by changing the signal with different distance transmission degradation and with different signal to noise ratio (SNR).
