“…Efficient multiwavelength operation of the Mamyshev regenerator with uni-directional data flow has been theoretically proposed by introducing suitable dispersion management [5]- [7]. In the present work, we report and further interpret the first experimental attempt with the latter scheme using four 600-GHz-spaced 10-Gb/s wavelength-division-multiplexing (WDM) channels within an all-fiberized dispersion-managed device [8].…”

Abstract-We experimentally investigate a dispersion-managed four-channel 2R regenerator that relies on self-phase modulationinduced spectral broadening and offset filtering at four shifted wavelengths. The device consists of several alternating sections of dispersion-compensating fibers and single-mode fibers. Due to this arrangement and the use of low duty-cycle return-to-zero pulses, nonlinear interchannel effects are sufficiently mitigated resulting in almost no additional degradation compared to the single-channel case.

“…A further factor to improve the use of the capacity provided by TONs (here WR networks) is the utilization of new all-optical devices such as tunable optical amplifiers [20], [21], optical regenerators [22], [23], and all-optical wavelength converters (AOWC) [24]. In particular, although new techniques are suggested as an alternative to avoid wavelength conversion in optical networks [25], [26], AOWCs may play a key role for reducing the block of connections on future WR networks [27]- [29] and are of central interest for this work.…”

Future Internet infrastructure will require the utilization of new all-optical devices able to enhance the use of fiber capacity. Nevertheless, before deploying such devices, it is necessary to test them under conditions similar to the ones of commercial networks and to evaluate their impact on real-world applications. In this work we investigate the performance of a tunable fiber fourwave mixing all-optical wavelength converter (AOWC) on a videostreaming carried through a field-trial network. This analysis is performed by measuring the packet-error rate (PER) degradation caused by the AOWC for different wavelength separations between the input and output optical carriers. To the best of our knowledge, this is the first time that such a cross-layer effect is systematically evaluated for an AOWC. A dynamic polarization controller was successfully used to prevent the FWM efficiency variations that were caused by the changes in the state-of-polarization of the video signal. Our results show that the AOWC introduced a maximum power penalty of 2.5 dB for wavelength separations of up to 12 nm. We also find that such a penalty is related to the optical signal-to-noise ratio degradation induced by the converter.
