(b) A fiber optic link consists of two types of fibers, followed by an amplifier. The first fiber is 40 km long and its loss coefficient is 0.046 km". The second fiber is 60 km long and its loss coefficient is 0.072 km'. The splicing loss (to splice these fibers) is 0.5 dB. An amplifier of gain 22 dB is used after the second fiber. If the optical signal power at the end of the fiber optic link is -2 dBm, find the input optical signal power in dBm units.
