Optical fiber uses the property of Total internal refraction of light for the transmission of data
TOTAL INTERNAL REFRACTION : total internal reflection takes place at the boundary between two transparent media when a ray of light in a medium of higher index of refraction approaches the other medium at an angle of incidence greater than the critical angle.
This prevents any loss of energy and helps in efficient transmission of information
