Unformatted text preview: What is the dispersion limited maximum fiber length? How much will it change if the pulses were unchirped? Neglect the laser linewidth and assume that 2 = -20 ps 2 /km. 3. Calculate the threshold power for stimulated Raman scattering for a 20 km fiber link operating at 1.55 m and having a loss of 0.2 dB/km. Assume that A eff =50 m 2 and g R =5x10-13 m/W. Suppose the pump is a 1 ps long pulse. How does that change the calculation?...
