Experimental demonstration of tolerance to FWM crosstalk in wavelength-swept WDM access systems

Abstract

Abstract:We confirm the tolerance of our proposed wavelengthswept wavelength division multiplexing (WDM) access system to fourwave mixing (FWM) crosstalk induced during fiber transmission. Since wavelength-swept light is employed as the carrier in the proposed system, there is little mutual interaction between different channel signals. Therefore, the tolerance to FWM crosstalk of the proposed technique is superior to that of conventional methods based on continuous-wave carriers. As a proof-of-concept, we perform experimental 10-and 20-km single-mode fiber transmissions of four-channel 1.25 Gb/s/ch WDM signals with a 12.5 GHz spacing, and show that FWM crosstalk has no serious impact even with a high optical power of +19 dBm.

“…Several techniques been done to achieve an effective reduction of FWM. Wavelength swept WDM, the allocation of polarization and effective frequency, WDM/TDM (wavelength/time division multiplexing), and non-uniform spacing of channels ware applied [23][24][25][26][27][28][29][30]. These techniques are needing an extra complexity in system design or at least needing a compensator to improve the signal dispersion.…”
