A step index fibre has core and cladding refractive indices 1.466 and 1.460 respectively. If the wavelength of light is 0.85 μm and diameter of the core is 50 μm, find the normalized frequency and the number of modes supported by the fibre. The optical power in an optical fiber is reduced to 25% of its original value after propagating through a 500 m long fibre. What is the fibre loss in dB/km?
