An analytical approach to incorporate the cross-phase modulation (XPM) and self-phase modulation (SPM) to the calculation of system bit-error rate (BER) in a multispan intensity-modulation direct-detection (IM-DD) WDM system is presented in this paper. The effects of three important link parameters such as pump and probe power and span length, on the system performance have been investigated in terms...
Cross-phase modulation (XPM) changes the state-of-polarization (SOP) of the channels that leads to amplitude modulation of the propagating waves in a WDM system. Due to the presence of polarization mode dispersion (PMD), the angles between the SOP of the channels change randomly and the modulation amplitude fluctuation in the perturbed channel becomes random. We analytically derive the dynamic equation...
The use of transparent free-space optics (FSO) allows the adoption of DWDM transmission enhancing the capacity of optical wireless link exploiting the full capacity of optical fibers. 40 Gbps data rates were obtained by time-multiplexing four 10 Gbit/s electrical sequences with a pattern length of 2. On field test on a real 60 m long transparent FSO link was performed so two devices to allow the necessary...
In this paper, crosstalk induced by cross phase modulation (XPM) and stimulated Raman scattering (SRS) in a multiwavelength subcarrier multiplexed transmission system is analyzed. Then combined effect of SRS and XPM induced crosstalk in the system performance is investigated. It is found that SRS dominates at lower modulation frequency with large channel spacing while XPM at higher modulation frequency...
Aa analytical approach is presented for modeling crosstalk and to evaluate the bit error rate (BER) performance in a wavelength division-multiplexing (WDM) network for link with optical cross connect (OXC) without wavelength converter. Factors that affect the magnitude of crosstalk in the OXC are investigated and parameters that play important role in determining magnitude of crosstalk and BER are...
An analytical approach is presented for modelling crosstalk and to evaluate the bit error rate (BER) performance in a wavelength division multiplexing (WDM) network for link with optical cross connect (OXC). Factors that affect the magnitude of crosstalk in the OXC are investigated and identified. The effects of OXC induced crosstalk on the BER performance is evaluated at a bit rate of 10 Gb/s by...
