“…Therefore, the fiberinput power should be kept lower than the SBS threshold that would define the maximum power that can be coupled into the fiber. There are numerous studies of this phenomenon dealing with power threshold determination which represents the limit on the transmit power but many of them are very complex [6][7][8][9][10]. This study deals with SBS and Rayleigh backscattering in the continuous wave (CW) regime.…”

The behavior of stimulated Brillouin scattering (SBS) and Rayleigh backscattering phenomena, which limit the forward transmission power in modern, ultra-long haul optical communication systems such as dense wavelength division multiplexing systems is analyzed via simulation and experimental investigation of threshold and maximum power. Evolution of SBS, Rayleigh scattering and forward powers are experimentally investigated with a 25 km segment of single mode fiber. Also, a simple algorithm to predict the generation of SBS is proposed where two criteria of power thresholds was used for comparison with experimental data.

“…Figure 6 shows a curve of the evolution of the optimal power for different number of channels in agreement with (20). Table 2 is obtained using Equations (17) (18) and (20). It shows the maximum value of optimum power (P o_srs ) and maximum length (L max ) in a SRS-ASE domain.…”

“…If the zero dispersion wavelength is far of the WDM signal bandwidth, the right or left extreme channels suffer most (depending on the sign of D). Figure 6 shows a curve of the evolution of the optimal power for different number of channels in agreement with (20). Table 2 is obtained using Equations (17) (18) and (20).…”

Limitations imposed by Four-Wave Mixing (FWM), Amplified Spontaneous Emission (ASE), dispersion and Stimulated Raman Scattering (SRS) on a multi-spam DWDM system are theoretically studied. In this work, expression for the linear dispersion parameter D has been defined as a function of number of channels in order to separate FWM and SRS effects and calculates both maximum fibre length and optimum power. Additionally, our simulation results consider the effect of ASE noise from Erbium Doped Fibre Amplifiers (EDFAs). This theoretical analysis yields a set of design criteria from optimized multi-span DWDM systems.

“…Figure 10 shows the values of optimum power in a system limited by FWM, for − < < ⋅ − D 2 2ps (km nm) 1 the optimum power is between 0.1 to 0.4 mW. Note that the values are not sensitive to number of channels and they are far from the power threshold of stimulated Brillouin and Raman scattering [15][16][17][18][19].…”

Dense wavelength division multiplexing (DWDM) systems are normally limited by stimulated Brillouin scattering (SBS), stimulated Raman scattering (SRS), self-phase modulation (SPM), cross-phase modulation (XPM) and four-wave mixing (FWM) besides amplified spontaneous emission (ASE) noise from erbium-doped fiber amplifiers (EDFAs). In this paper, theoretical calculation of FWM-based limits and noise from EDFAs in the 1535-1565 nm region, are reported. Results show that FWM power per channel extended from −55 to −20 dBm for dispersion values of 0.0, 0.5, 1.0 and 1.5 ps (nm⋅km) −1 . In a similar manner, for negative dispersion coefficient (D) values ranging from 0.0 to −1.5 ps (nm⋅km) −1 , the FWM power per channel extended from −60 to −30 dBm. As for the maximum span length, the calculations demonstrated a rigorous limitation due to noise, suggesting error compensation techniques. A full set of results for the design of multi-span links is included.
