The signal propagation in a fiber is simulated. Fiber nonlinear effects are ignored. The Fourier transform of the input signal field is taken to obtain the input spectrum. It is multiplied by the fiber transfer function and then the inverse Fourier transform leads to the output pulse.

2b.1 Let = 0 s.s/m, = (1.5 e-6)/3 e8 s/m and = 0 m-1 . Plot fiber input and output field envelopes and electric field distributions. Is the pulse width at the fiber output different from that at the input? Explain.
2b.2 Let = -21 ps.ps/km, = 0 s/m and = 0 m-1. Does the pulse undergo a time-shift? Explain.
2b.3 Let = -21 ps.ps/km, = (1.5 e-6)/3 e8 s/m and = 0 m-1. Plot fiber input and output field envelopes and electric field distributions.
2b.4 Repeat 2b.3 with loss coefficient = 0.2 dB/km. Does the fiber loss affect the pulse broadening? Compare the pulse widths and peak amplitudes corresponding to 2b.3 and 2b.4.
2b.5 Repeat 2b.2 to 2b.4 with a rectangular pulse.
