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.


What type of Electromagnetic radiation used in optical fiber communication?

Optical fiber communication primarily uses infrared light as the type of electromagnetic radiation. This is because infrared light has a longer wavelength that is well-suited for transmitting data over long distances through optical fibers with minimal signal loss.
