What are the 4 types of question?

What is meant by attenuation in Optical Fiber Communication?
When an optical signal of a given wavelength travels in the fiber it looses power. The amount of loss of power per Km length of fiber is called its attenuation.
A=10*LOG10(POUT/PIN) dB/Km
Where POuT is optical power after 1 Km
PIN is th epower launched in the Fiber.
