“…As a result, a difference in residual dispersion is present after transmission. In most OPC-based transmission experiments reported so far, the difference in residual dispersion is compensated for by optimizing the postcompensation after transmission on a per channel basis [15], [16], [25], [27]- [32], [39], [40]. Alternatively, the third-order dispersion can be compensated for using a slope compensator [38].…”

“…It is foreseen that many transmission links will be upgraded on a per channel basis, resulting in mixed data rates and mixed modulation formats in the same fiber. As shown in [32], OPC can be employed to transmit different modulation formats and data rates over the same line without the use of a periodic dispersion map.…”

Abstract-In this paper, we review the recent progress in transmission experiments by employing optical phase conjugation (OPC) for the compensation of chromatic dispersion and nonlinear impairments. OPC is realized with difference frequency generation (DFG) in a periodically poled lithium-niobate (PPLN) waveguide, for transparent wavelength-division multiplexed (WDM) operation with high conversion efficiency. We discuss extensively the principle behind optical phase conjugation and the realization of a polarization independent OPC subsystem. Using OPC for chromatic dispersion compensation WDM 40-Gb/s long-haul transmission is described. As well, transmission employing both mixed data rates and mixed modulation formats is discussed. No significant nonlinear impairments are observed from the nonperiodic dispersion map used in these experiments. The compensation of intrachannel nonlinear impairments by OPC is described for WDM carrier-suppressed return-to-zero (CSRZ) transmission. In this experiment, a 50% increase in transmission reach is obtained by adding an OPC unit to a transmission line using dispersion compensating fiber (DCF) for dispersion compensation. Furthermore, the compensation of impairments due to nonlinear phase noise is reviewed. An in-depth analysis is conducted on what performance improvement is to be expected for various OPC configurations and a proof-of-principle experiment is described showing over 4-dB improvement in Q-factor due to compensation of nonlinear impairments resulting from nonlinear phase noise. Finally, an ultralong-haul WDM transmission of 22 × 20-Gb/s return-tozero differential quadrature phase-shift keying (RZ-DQPSK) is discussed showing that OPC can compensate for chromatic dispersion, as well as self-phase modulation (SPM) induced nonlinear impairments, such as nonlinear phase noise. Compared to a "conventional" transmission link using DCF for dispersion compensation, a 44% increase in transmission reach is obtained when OPC is employed. In this experiment, we show the feasibility of using only one polarization-independent PPLN subsystem to compensate for an accumulated chromatic dispersion of over 160 000 ps/nm. Index Terms-Dispersion compensation, differential phaseshift keying (DPSK), differential quadrature phase-shift keying (DQPSK), duobinary, fiber-optics communications, nonlinear phase noise, phase conjugation, phase-shift keying, periodically poled lithium niobate (PPLN), spectral inversion.

“…It has been experimentally shown that OPC can compensate for chromatic dispersion [11]- [15], self-phase modulation (SPM), [16] and also intrachannel nonlinear impairments [17]- [19]. The key advantages of OPC are that simultaneous processing of multiple channels is possible [20] and that an OPC is transparent to modulation format and data rate [21].…”

Network Performance Improvement of All-Optical Networks Through an Algorithmic Based Dispersion Management Technique

et al. 2011

View full text Add to dashboard Cite

Network blocking performance due to wavelength continuity constraint in a well-connected all-optical network can be efficiently reduced by utilizing wavelength converters. Nevertheless, the introduction of high bit rate optical services with strict tolerance to signal quality would have a serious impact on the overall network performance since in this circumstance, a request can be blocked due to unacceptable signal quality of potential routes. Chromatic dispersion tolerance, for example, is reduced by the square of the bit rate. By extending the typical application of parametric wavelength converter in solving a wavelength continuity problem, this paper aims to enhance chromatic dispersion management through an improved wavelength conversion algorithm. Consequently, significant improvement in network performance has been demonstrated through reduction in the dispersion effect when the proposed engineering rule is included in the conversion process.
