How Does Fiber Optic Work?

What is Fiber Optic?:

What is Fiber Optic? We're used to the idea of information traveling in different ways. When we speak into a landline telephone, a wire cable carries the sounds from our voice into a socket in the wall, where another cable takes it to the local telephone exchange. Cellphones work a different way - they send and receive information using invisible radio waves - a technology called wireless because it uses no cables. Fiber optics works a third way. It sends information coded in a beam of light down a glass or plastic pipe.

What it is made up of?:

What it is made up of? A fiber optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers; one cable can have as few as two strands or as many as several hundred. Each strand is less than a tenth as thick as a human hair and can carry around 25,000 telephone calls, so an entire fiber optic cable can easily carry several million calls.

How does it work?:

How does it work? Light travels down a fiber-optic cable by bouncing repeatedly off the walls. Each tiny photon bounces down the pipe. Now you might expect a beam of light, traveling in a clear glass pipe, simply to leak out of the edges. But if light hits glass at a really shallow angle (less than 42 degrees), it reflects back in again—as though the glass were really a mirror. This phenomenon is called total internal reflection. It's one of the things that keeps light inside the pipe. The other thing that keeps light in the pipe is the structure of the cable, which is made up of two separate parts. The main part of the cable—in the middle—is called the core and that's the bit the light travels through. Wrapped around the outside of the core is another layer of glass called the cladding. The cladding's job is to keep the light signals inside the core. It can do this because it is made of a different type of glass to the core. (More technically, the cladding has a lower refractive index.)

Fiber Optic Internet in India:

Fiber Optic Internet in India There is one fiber optic network in India which provides high-speed internet from speeds upto 100Mbps to 1Gbps. JioFiber by Reliance Jio, which was launched on 5 th September 2019, offers many plans from INR 699 per month to INR 8499 per month to suit every need. Along with broadband it is offering various other services such as Home Networking – To access all your important files, images, videos anytime, anywhere Gaming – Zero-latency gaming, which is India’s first multi-player platform Device Security – Device Security for upto 10 devices 4K TV – Yes! A 4K Television and set top box with annual subsctiption
