| description | In this paper the combined impact of stimulated Raman scattering (SRS)
and four-wave mixing (FWM) on the downlink channel performance of dense wavelength division multiplexed-gigabit
passive optical networks (DWDM-GPONs) has been compared with the single impact
of FWM via signal-to-crosstalk ratio (SXR) simulations performed on center
downlink channels of 7-, 15- and 31-channel DWDM-GPON systems. Simulation
results show that SRS compensates negative impacts of FWM and
compensation significance enhances with increasing channel numbers and channel
spacing values. At high channel
spacing values of 50 GHz and 100 GHz, variation of SXR can display a strong oscillatory behavior in very short channel
length variations of 0.5 km. The combined impact of SRS and FWM enhances the
maximum oscillation amplitude of SXR variation with respect to the single
impact of FWM at those channel spacing values. It has been observed that Raman
gain exhibits an approximately linear variation with channel input powers in
0.1-5 mW range and it increases with increasing fiber lengths, channel spacing
values and channel numbers. Results of this research emphasize the significant
difference between the combined impact of SRS and FWM and the single impact of
FWM on DWDM-GPON systems and give important hints for current DWDM-GPON
implementations. |
