| Abstract: | The mechanism of nonlinear crosstalk in WDM-SCM fiber communication systems is investigated. Then the crosstalk suppression method of complementary modulation of twin carriers is introduced and discussed. Aiming at the limitation of this method, a new method named symmetric carrier complementary modulation is presented, and it has shown satisfactory effect in crosstalk reduction. |
| Keywords: | crosstalk wavelength division multiplexing (WDM) subcarrier multiplexing (SCM) stimulated Raman scattering (SRS) cross-phase modulation (XPM) |
