1. Calculate the carrier frequency for optical communication systems operating at 0.88, 1.3, and 1.55 µm. What is the photon energy (in eV) in each case?
2. Calculate the transmission distance over which the optical power will attenuate by a factor of 10 for three fibers with losses of 0.2, 20, and 2000 dB/km. Assuming that the optical power decreases as exp(-αL), calculate α (in cm-1) for the\ three fibers.
