SOLVED: A certain optical fiber has an attenuation of 0.6 dB/km at 1300 nm and 0.3 dB/km at 1550 nm. Suppose the following two optical signals are launched simultaneously into the fiber: an optical power of 150 µW at 1300 nm and an optical power of 100 µW at 1550 nm. What are the power levels in µW of these two signals at (a) 8 km and (b) 20 km?
