Suppose now the series of digital light pulses (101010…,) of light transmitted at a bit rate of 2.5 Gb/s is launched into a fiber from a laser diode with a 3 nm spectral width. Again, the fiber has a dispersion coefficient of 20 ps/nm-km. Approximately how far can these pulses travel before they are unrecognizable. Use the hint given in problem 2
