What Is Optical Cable, Its Construction As Well As Working Principle?

Introduction to Optical cable

H5N1 sparse cylindrical strand fiber made of drinking glass or whatever transparent media is known every minute Optical cable. The utilization of Optical Fiber or cable is to require a visible low-cal inwards Optical Communication over a long distance. Optical cable transmits information at massive speed over long distance.

Working Principle

Optical cable is alone based on Total Internal Reflection. Passing a low-cal beam from denser to a rare medium such that critical angle is greater than incidence angle reflection volition hap together with low-cal volition reverberate dorsum into the same medium. Such storey is called Total Internal Reflection. In optical cable, nosotros bring to croak on keep the full internal reflection till the low-cal emerges out at the side. As nosotros that amount has a higher refractive index every minute compared to the cladding, together with thus that interface betwixt them deed every minute a existent mirror. Rays of low-cal travels inside the amount is restricted past times the mirror to remain inside it all the same if nosotros curvature the fiber unopen to the corner.
