How do fiber optical cables work?

Mumbai: Fibre Optic cables are perhaps one of the most important inventions in modern times.

It is a technology that uses glass or plastic fibers to transmit data over long distances. What you say or speak over the phone, send messages or download, the data travels through these fibre optics.

You must be wondering how it is possible for a cable to transmit such huge amounts of data over long distances.

Well, it is based on a complex internal reflection and refraction mechanism along with some highly engineered core glass along with an outside cladding layer. So without further ado, let’s check out how Fibre optical cables work.
