Employing Photonic Crystal Fiber to Improve CSO/CTB Performances in a Two-Wavelength WDM Transport System

A two-wavelength WDM externally modulated transport system employing PCF as a dispersion compensation device to compensate the fiber dispersion and to reduce the XPM induced crosstalk is proposed and demonstrated. In comparison a two-wavelength WDM externally modulated transport system without using PCF, good performances of CSO and CTB were obtained accompanied by acceptable CNR in our proposed system over a combination of 100-km SMF and 3.6-km PCF.
