Give reason why an optical fibre is used to transmit a light signal over a long distance without any loss of energy
Adi S.
Optoelectronics 1. An optical signal at a specific wavelength has lost 55% of its power after traversing 3.5 km of fiber. What is the attenuation in dB/km of this fiber? 2. When the mean optical power launched into an 8 km length of fiber is 100 μW, the mean optical power at the fiber output is 4 μW. Determine: a) The overall signal attenuation in dB. b) The signal attenuation per kilometer for the fiber. c) The overall signal attenuation for a 10 km optical link using the same fiber with splices at 1 km intervals, each giving a 1 dB loss. d) The numerical input/output power ratio in c) 3. Direct band-to-band photon absorption and emission can take place only at wavelengths for which the photon energy is greater than the band gap energy. Prove that if the band gap energy, Eg, is given in eV, the peak emission or absorption wavelength in μm is: λ = 1.24/Eg. 4. A simple empirical relation that gives the band gap energy in eV for InGaAsP in terms of x and y is: Eg = 1.35 - 0.72y + 0.12y^2. Find the band gap energy and the peak emission wavelength of In0.73Ga0.27As0.63P0.37.
