How Telecommunication Is Developed Through Fibre Optics
People are used to the idea of information traveling in different ways. When someone speaks into a landline telephone, a wire cable carries the sounds of that person’s voice. That person’s voice travels into a socket in the wall. Another cable takes it to the local telephone exchange.

Cell phones work differently. Radio waves are used to send and receive information. This technology is called wireless. It doesn’t use any cables. There is a third way that fiber optics work. It also sends information coded in a beam of light down a plastic or glass pipe. Fiber optics were originally developed for endoscopes in the 1950s. This technology was originally developed to help doctors see inside the human body without cutting it open first. Engineers found a way to utilize the same technology to transmit telephone calls at the speed of light in the 1960s.

Optical Technology

There are 100 or more incredibly thin strands of plastic or glass that make up a fiber optic cable. It is also known as optical fibers. Each fiber is less than a tenth as thick as human hair. It can carry 10 million telephone calls.

These types of cables carry information between two places. Optical light based technology is used to accomplish this. For example, you may want to send information to your friend’s house down the street. This information is being sent from your computer using fiber optics. Your computer can be hooked up to a laser. Electrical information could be converted from the computer into a series of light pulses. The laser would be fired down the fiber optic cable. Then the light beams would emerge at the other end. This happens after these light beams travel down the cable.

A photoelectric cell, which is a light detecting component, will be needed for your friend. This will turn the pulses of light back into electrical information that your friend’s computer will understand.

Optical cables carry light signals down modes. The path that a light beam follows down the fiber is called a mode. One type of mode is called a single mode. This is the simplest type of optical fiber. Another type of mode is called a multi-mode. There is a mode to go straight down the middle of the fiber. Another mode is to bounce down the fiber at a shallow angle. There are other modes as well. They involve bouncing down the fiber at other angles with more or less steep.
