What is Optical Fiber?
So, Fiber internet is sort of popular lately . Until a couple of years ago, broadband connections were rarely fiber based. Or wireless, WiMax was used or the web was given to the users through normal internet cable.
Now the demand for fiber internet has increased within the market. the rationale for are often "> this is often that prime speed can be achieved through fiber internet, which suggests that data transfer is far faster.
albeit fiber internet is new for a standard user, fiber has been used for several years within the internet world. In fact, fiber cables were used in 1950 for medical use.
it had been invented to permit doctors to ascertain inside the patient's body through a fiber cable without extensive surgery.
In a way, the network of internet within the whole world isn't possible without fiber. Fibers are spread round the world sort of a spider web and this is often the rationale that you simply have internet access.
However, we tell you ways this glass fiber technology works.
What is glass fiber :-
You can consider fiber optics because the medium of transmission. otherwise you can consider it as a skinny pipe whose data traverses at the speed of the front light.
Fiber cables also are thinner than hairs and are for much longer . Fine fiber optics also are protected with an outer layer from multiple hairs directly , in order that they are doing not break.
These are placed during a bundle and are called optical cables. The specialty of fiber optics is that they carry data through light for long distances.
Since the speed of sunshine is extremely high, they're wont to transmit data. If you check out fiber optics carefully, you'll find that there's empty space inside the fine wire even from the hair.
If you hit the laser from one end in empty space, you'll be ready to see that light at the opposite end. Actually, this system is employed when the glass fiber is cut or there's some trouble in it.
quite one fiber strands reside inside a cable. Even the cables that go inside the ocean have thousands of thin fibers that are placed inside a cable. they're also called cores. That is, 10 fibers are getting into one cable, you'll call them 10 cores.
How do Fiber optics work ~
Think of it sort of a pipe during which data is transmitted through light. The fiber optics wall is meant in such how that the sunshine collides with it to travel far enough and not spread around.
But what if the wire twisted from somewhere? In such a situation, the sunshine won't be ready to proceed . Light didn't plow ahead , ie internet stopped? It happens. But to stop this, there's cladding inside the cable through which the sunshine bounces continuously.
The cladding also can be called mirror lined walls. The cladding doesn't absorb light therefore the light goes forward. For these reasons, light travels for several kilometers comfortably.
Why is fiber optics fast and secure?
As we mentioned earlier, here the info travels through light, obviously the speed of sunshine is achieved in vacuum up to about 3 lakh kilometers per second, so you'll guess how briskly the info can travel.
there's currently nothing faster than light and it's utilized in fiber optics. Talking about traditional internet cable, there's transmission with electric signal which is extremely slow compared to light.
Fiber optic is additionally considered better in terms of knowledge security. Because hacking a fiber optic cable is hard and expensive compared to satellite and copper wire.
