TL;DR: The effectiveness of return-to-zero (RZ) data pulses with varying duty cycles and digital backpropagation (DBP) in reducing nonlinear distortion in wavelength-division- multiplexed (WDM) links with 3, 5, 7 and 9 channels is considered.
Abstract: We investigate the transmission performance of 224Gbit/s polarization-division-multiplexed 16-state quadrature amplitude modulation (PDM-16QAM) for systems employing standard single mode fiber (SSMF) and erbium doped fiber amplifiers (EDFAs). We consider the effectiveness of return-to-zero (RZ) data pulses with varying duty cycles and digital backpropagation (DBP) in reducing nonlinear distortion in wavelength-division- multiplexed (WDM) links with 3, 5, 7 and 9 channels. Similar improvement in transmission reach of 18-25% was achieved either by pulse-carving at the transmitter or by DBP, yielding maximum transmission distances of up to 1760km for RZ-pulse-shapes and 1280km for NRZ.

TL;DR: In this paper, a model for quantum BER estimation in polarization encoded quantum key distribution systems is presented, where both TDM and WDM based polarization control schemes are analyzed and shown that TDM presents some important advantages when compared with WDM control scheme.
Abstract: A model for quantum BER estimation in polarization encoded quantum key distribution systems is presented. Both TDM and WDM based polarization control schemes are analyzed. It is shown that TDM presents some important advantages when compared with the WDM control scheme. In WDM, the polarization decorrelation between the reference and data signals is an intrinsic and very limitative impairment. This effect has a contribution to quantum BER that increases with the propagation distance, and is highly dependent on the fiber polarization mode dispersion. In the TDM control scheme, the polarization decorrelation is less critical and other issues, like the single photon detector and feedback polarization control system performance tend to dominate. We show that for long distances the fiber losses represent the main contribution to the total quantum BER. Nevertheless, for distances shorter than 70 km and frequencies higher than 5 MHz the after pulse detections provide an important contribution to the total quantum BER.

01 Oct 2007TL;DR: In this article, the evolution of the degree of polarization is determined by the interplay between the coherence properties of the pulse and fiber birefringence, and it is shown that the pulse polarization changes of statistical pulses in single-mode fibers.

TL;DR: A new theoretical analysis of the interferometric polarization-mode dispersion measurement predicts, in the limit of large PMD, a new relationship to the highly mode-coupled principal states model, which is confirmed by computer simulation of the ratio of the mean differential group delay.
Abstract: A new theoretical analysis of the interferometric polarization-mode dispersion (PMD) measurement predicts, in the limit of large PMD, a new relationship to the highly mode-coupled principal states model. This theory is confirmed by computer simulation of the ratio of the mean differential group delay (DGD) to the interferometric PMD. Jones matrix eigenanalysis and wavelength scanning with extrema counting are shown to measure the mean DGD independently of the optical source spectrum, whereas interferometrically measured PMD is shown to depend on the optical source spectrum as well as on the characteristics of the fiber to be measured.

TL;DR: A time lens based on clock-driven phase modulators followed by linear dispersion accurately removes timing-jitter and greatly improves bit-error-rate performance in DWDM dispersion managed soliton transmissions.
Abstract: A time lens based on clock-driven phase modulators followed by linear dispersion accurately removes timing-jitter. When used prior to the receiver, the time lens greatly improves bit-error-rate performance in DWDM dispersion managed soliton transmissions.
