“…We performed bit-error-rate (BER) measurements on both channels for both single-and dual-channel operation [16]. Having artificially degraded the extinction ratio of the input pulse streams the corresponding BER measurements confirmed that complete correction of the ~4 dB power penalty (at BER = 10 −9 ) can be achieved at the regenerator output for both channels in the presence of the interfering channel.…”

“…Mitigation of those degradations can be achieved by complete and rapid "walkthrough" of the data pulses within the adjacent channels. This can be achieved either by exploiting some form of specific dispersion management within complex fiber assemblies [22] by using dispersion decreasing fiber [23], or by using bidirectional propagation [24,16].…”

Abstract:We demonstrate a regenerative optical grooming switch for buffer-less interconnection of metro/access and metro/core ring networks with switching functionality in time, space and wavelength domain. Key functionalities of the router are the traffic aggregation with time-slot interchanging (TSI) functionality, the WDM-to-ODTM multiplexing and the OTDM-to-WDM demultiplexing of high-speed channel into lower bitrate tributaries as well as multi-wavelength all-optical 2R regeneration of several higher-speed signals. BER and Q-factor measurements of different switching scenarios show excellent performance with no error floor and Qfactors above 21 dB. ©2009 Optical Society of America

“…A number of studies have been reported on all-optical signal regeneration using HNLF, among which few focused on high-speed (e.g. 160-Gb/s) multi-channel regeneration [3][4][5][6]. Bidirectional multiplexing can be used for two-channel regeneration where pattern-dependent nonlinear inter-channel interaction is avoided by the rapid walk-through between the signals traveling in opposite directions.…”

Simultaneous regeneration of four high-speed (160 Gbit/s) wavelength-division multiplexed (WDM) and polarization-division multiplexed (PDM) signals in a single highly nonlinear fiber (HNLF) is demonstrated. The regeneration operation is based on four-wave mixing in HNLF, where the degraded data signals are applied as the pump. As a result, the noise on both '0' and '1' levels can be suppressed simultaneously in our scheme. The stimulated Brillouin scattering (SBS) from the continuous wave (CW) is suppressed by cross-phase modulation (XPM) from the data pump, relieving the requirement of external phase modulation of the CW light. Mitigation of the inter-channel nonlinearities is achieved mainly through an inter-channel 0.5 bit slot time delay. Bidirectional propagation is also applied to relieve the inter-channel four-wave mixing. The multi-channel regeneration performance is validated by bit-error rate (BER) measurements. The receiver powers at the BER of 10 −9 are improved by 1.9 dB, 1.8 dB, 1.6 dB and 1.5 dB for the four data channels, respectively. ©2014 Optical Society of America

Field experiments of 42.7 / 128.1 Gb/s WDM-OTDM transmultiplexing and all-optical dual-wavelength regeneration at the OTDM rate are presented. By using the asynchronous retiming scheme, we achieve error-free buffer-less data grooming with time-slot interchange (TSI) capability for OTDM meshed networking. We demonstrate excellent performance from the system, discuss scalability, applicability, and the potential reach of the asynchronous retiming scheme for transparent OTDMdomain interconnection.
