Abstract :
A theory describing the propagation of signal and noise through a lossless linear dispersive singlemode fiber near zero first-order dispersion point is presented. Using the small signal analysis approach, this theory has been applied to modulation and noise characteristics of a laser diode, emitting near the fiber zero-dispersion wavelength, to obtain the small signal frequency response and the signal relative intensity noise (RIN) at the output of the fiber. It has been shown that, for very long broad-band transmission lines, dispersion effects may be no longer negligible also at zero-dispersion wavelength
