چکیده
AbstructThe spectral characteristics of cross-phase modulation (XPM) in multispan intensity-modulation direct-detection (IM-DD) optical systems are investigated, both experimentally and theoretically. XPM crosstalk levels and its spectral features are found to be strongly dependent on fiber dispersion and optical signal channel spacing. Interference between XPMinduced crosstalk effects created in different amplified fiber spans is also found to be important to determine the overall frequency response of XPM crosstalk effects. XPM crosstalk between channels with different data rates is evaluated. The crosstalk level between higher and lower bit eate channels is found to be similar to that between two lower bit rate channels. The effect of dispersion compensation on XPM crosstalk in multispan optical systems is discussed and per span dispersion compensation was found to be the most effective way to minimize the effect of XPM crosstalk.

متن کاملAnalytical Assessment of the Q-factor due to Cross-Phase Modulation (XPM) in Multispan WDM Transmission Systems
In this paper cross-phase modulation (XPM) and its impact on multispan NRZ-modulated wavelength division multiplexing (WDM) systems is examined. An analytical model is presented to assess the signal degradation. The impairments due to XPM are related to a Q-factor. The presented formulas are examined for different dispersion compensation schemes and also mixed-fiber systems. The analytical mode...
متن کامل1 Impact of Nonlinearities on Fiber Optic 2 Communications 3
A number of third order nonlinear processes can occur in single-mode fibres and an 8 understanding of such phenomena is almost a prerequisite for actual lightwave-system designers. 9 In this paper we review the main limitations imposed by several nonlinear effects, namely the self10 and cross-phase modulation, four-wave mixing, stimulated Raman scattering and stimulated 11 Brillouin scattering,...

A Wavelength Division Multiplexing (WDM) system is a high-speed optical transmission system that simultaneously transports optical signals of different wavelengths over a single optical fiber. WDM was developed as a next generation optical signal transport technology after traditional Time Division Multiplexed (TDM) systems offering much greater potential capacities. TDM is the most popular tec...
متن کاملuncompensated link with backward-pumped distributed Raman amplification
We present experimental and numerical investigations of Kerr nonlinearity compensation in a 400-km standard single-mode fiber link with distributed Raman amplification with backward pumping. A dual-pump polarization-independent fiber-based optical parametric amplifier is used for mid-link spectral inversion of 5 × 28-GBd polarization-multiplexed 16QAM signals. Signal quality factor (Q-factor) i...
