In optic fibers the how do v transmitt the information? will not there be interference of light as different wavelength of light travel in core?
 
Physics news on Phys.org
The speed that light travels is independent of the wavelength. So the signal at any point in the cable is in the same state, or modulation, as it was at transmission.

Not quite -- dispersion can be a design issue in multi-mode fibers:

Ok I see. Though it is kept to a minimum so that the signal is still understandable at the receiver.
