How many modes can be transmitted in multi mode fiber?

Multi mode fiber are optical fibers which support multiple transverse guided modes for a given optical frequency and polarization. The number of guided modes is determined by the wavelength and the refractive index profile.


How can you define number of modes in optical fiber?

A definition on top of my head, it's the number of frequencies allowed to be carried by the Optical Fiber Cable, It depends on the Ko, thickness and Numerical Aperture of the Fiber Cable.


What is the significance of normalized frequency in optical fiber?

If V is less than 2.405 then the fiber is mono mode but if V is greater than 2.405 then fiber is multimode. V number is also related with the number of modes is the fiber as: N = V2/ 2 for step index fiber and Number of modes for graded index fiber is N = V2/ 4.

What is meant by attenuation in optical fiber?

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.
