“…Furthermore, according to the results demonstrated in [8] DB was the most successful format for the utilization in MLR systems in comparison with NRZ and DPSK. In addition authors in [10] report, that DB demonstrated higher SE in comparison with NRZ, RZ and CSRZ in the long-haul high-data rate system with unequal channel spacing and MMFs. Moreover, the transmitter of DB is much less complicated in comparison with advanced modulation formats such as PAM, QAM and QPSK.…”

This paper aims at assessing of implementation of the concept of mixed systems in wavelength-divisionmultiplexing passive optical networks (WDM-PONs). At the first stage, the authors evaluate performance of two equalchannel transmission systems with non-return-to-zero (NRZ) and duobinary (DB) coding in terms of Q-factor, minimal channel spacing and supported data rate. At the second stage, two configurations of mixed transmission systems are proposed. The system with unequal channel spacing and multiple modulation formats (MMFs) as well as the system with mixed line rates (MLRs) and MMFs are investigated. The obtained results reveal that the impact of implementation of both systems is positive and concept of mixed transmission system can be considered as a potential solution for the increase of spectral efficiency (SE) of WDM-PON transmission system.

“…To satisfy the constantly increasing demand for higher network capacity, fiber optical transmission systems with wavelength division multiplexing (WDM) have been intensively studied and applied, as WDM technology allows using the available optical fiber resources more efficiently than alternative technologies [1]- [3]. It is possible to increase the WDM system throughput capacity either by increasing the data transmission speed in channels or the number of channels.…”

Fiber optical parametric amplifiers (FOPA) are well known for the variety of potential applications in alloptical signal processing. Many of these applications use the idler spectral components that are produced by the four wave mixing parametric process. The performance of parametric amplifiers and, therefore, also of generation of idler spectral components, is highly dependent on different factors, including stimulated Brillouin scattering (SBS) and polarization of the input signal. The aim of this article is to investigate the influence of pump phase modulation of parametric amplifiers, used for SBS mitigation, and the impact of mutual state of polarization mismatch of the input signal and the pump on the generation of idler spectral components. The obtained results have shown that it is crucial for systems with FOPAs to ensure that the input signal and the pump are co-polarised, as polarization dependant gain of 16.7 dB and 33.5 dB difference in idler generation was observed in the performed simulations. It was also found that applying the phase-modulation of the pump for SBS mitigation has caused 54 % idler spectral broadening. Therefore additional measures must be taken to avoid inter-channel crosstalk among the neighbour channels.

A communication system transmits and receives information from one place to another, where the separation between transmitter and receiver may be of few kilometers or transoceanic distances. Fiber-optic communication is one of such communication systems where optical fibers are deployed for information transmission. The capacity of a fiber-optic communication system is very high since it has large carrier frequency (Capacity~100 THz) in the visible or near-infrared region of the electromagnetic spectrum. The transmission of multiple optical channels over the same fiber has provided a simple way to extend the system capacity. Channel multiplexing can be achieved through time-division multiplexing (TDM) or frequency division multiplexing (FDM). In optical communication, FDM is known as wavelength division multiplexing (WDM). This chapter includes the discussion about the working principle of the WDM system, WDM components, classification of WDM system, and other supporting technologies.
