A fiber optic-based transmission system is used to connect 2 points in Surabaya and Semarang which is 300 km away. If a diode laser light source is used with a wavelength of = 1.55 µm and a power of P = 20 mW, the optical fiber is single mode step index of silica material with a difference in relative refractive index = 0.01 and an attenuation coefficient of a = 0.2 dB / km and a photodiode detector with sensitivity -45 dBm, how many pieces of optical fiber are needed to connect the two points. If a diode laser with a wavelength of 1.3 µm is used, what effect will it have on the transmission system? Explain and give examples to taste.
