Why settle for slow speed, high electricity costs and a technology invented a hundreds years ago if you can have the latest in data transmission at less the cost and many times the speed?
With the use of glass or plastic threads to transmit data the fiber optics is an upcoming technology. A bundle of glass threads capable of transmitting messages that are transformed into light waves is what makes the data fiber optics. Sharing a variety of technical details in the flowing article, I hope to make you have a better understanding of the subject of fiber optics. The functions will be demonstrated by explaining how the technology uses light energy to provide information and data to a variety of sources.
Engineering Science
Part of applied science consists of data fiber optics and the engineering behind it is comprised of the science and technology of transmitting data or energy. The basic fundamentals of fiber optics are defined through scientific processes and mathematical equations that fall closely under the realm of physics where you will find that the actual flow of the data can easily be put into observable and replicable systems. So even though most people do not understand “light” is can be show to them though scientific methods.
Data fiber optics or optic fibers are often used in the field of imaging optics, sensors, telecommunications, and lighting in general. This is mainly due to the data transmission speed and the fact that it doesn’t require electrical impulses to move the data. It is causing the need for electrical power in terms of data transmission to become nearly obsolete because the light transmits energy faster and cleaner than any other know technology.
Telecommunications and Data Fiber Optics
For you to fully understand the implications on technology by using fiber optics, we need to understand how it works in terms of telecommunications. By conducting signals over distance for communication purposes telecommunications was born. Telecommunications are widespread and there are many devices that assist in the spread of this communication, such as the radio, the fax machine and the television. One of the heavy factors in these mediums is the Data fiber optics technology.
A telecommunications system’s basic fundamentals are the transmitter, the receiver and the transmission medium. A transmitter is an electronic device that sends an electromagnetic signal with the aid of an antenna, essentially taking information and converting it to a signal for transmission which passes it on to the transmission medium. A receiver is, of course, the receiving end of the communication channel. The transmission medium is the material or device over which the signal is transmitted.
By serving as an effective transmitter of information the data fiber optics plays in the telecommunications process. Using light energy sent through glass has changed the way the world communicates and has revolutionized the process of telecommunications from this day and into the future.

Can Information be transfered Faster Than The Speed of Light ?
How about explaining how laser light transmitted in fiber optics can pass along information faster than the speed of light?
It is because the light coming out of the fiber optic cable is not the same light going into the cable. When you push light into the cable the pulse coming out is already at the other end of the cable. Think of the transmission of data as being like a stick. You push one end of the stick and the other end pokes your friend in the back. You have transferred energy faster than the speed of light.
The pressure of the light hitting one end of the fiber optic cable instantly exerts pressure on the other end of the cable instantly transfering the message faster than light. The light energy arrives later.
I disagree. I think the light coming out of a fiber is the same as the light that goes into it.

information cannot be transferred faster than the speed of light. The speed of light is the fastest speed any known object can travel. light does not work like a stick. it does not push other light in front of it. Also, if it did, it could only transfer the information at the same rate it was encoded as a signal. The encoding rate of the signal is significantly slower than the speed of light. You are seriously confused in how information is encoded and transferred via light.

Your idea doesn’t work. It’s intriguing, but no – Einstein’s theory of relativity describes how the speed of light is always constant, no matter where we view it from or what perameters are there.
There are however, some intermolecular particles called neutrinos that can transfer information faster than the speed of light – but the information is random, and therefore useless.

A book I read… can’t remember which one, lol. and my brain of course.
fiber optics work by the concept of total internal reflection. packets of light bounce around inside the fiber, until it reaches the other end. the packets travel at the speed of light, but the information you receive on the other end reaches you a little slower, because of all the extra path lengths caused by the reflections. information transmitted through a fiber optic cable does not travel faster than the speed of light.
your stick example is flawed.
in reality, rigid bodies are not perfectly rigid. if your stick is long enough, and you pushed one end of the stick, it will take a finite amount of time for the other end of the stick to react to your force. in other words, it takes time for the other end of the stick to "know" that the other end has been moved.
this delay is caused by a longitudinal wave traveling down the stick from you pushing on one end. the speed of the wave is incredibly fast, not no where near the speed of light. to observe this effect, you either need a reallllly long stick, or a material with low rigidity.
edit: the light going into a fiber optic cable IS the light you see at the other end. i think for some odd reason you’re confusing optic cables with regular wires. the electrons moving into one end of a wire is NOT the same electrons coming out the other end.
edit: the "pressure" or momentum of light is NOT transmitted instantaneously across a distance. the same way the end of a long stick does NOT instantaneously move if one end is moved. also, you are still confusing photons with electric current. they do NOT behave the same way. read my answer again.

Speed of light is what it is, a speed! Of course some time we’ll be moving faster than that to travel the universe.
A lot of beliefs were held in past that are proven wrong. It was believed we can’t travel faster than the speed of sound….Not too long ago.
