What is optical fiber and how does it work?

By niveksuhail
The rapid development of technology seems to be able to make an impossible thing possible. Call it telecommunications technology that is now becoming mediocre. In fact, telecommunications technology was once one of the things that was considered impossible.
But behind the success of telecommunications technology, there are several components that help the development of telecommunications, whose existence is rarely known to people. One of them is optical fiber, which is a core component that makes telecommunications technology what it is today. Without the existence of these components, it is possible that human telecommunications would not be as practical and easy as this.
Then what is optical fiber? Why is this important for the development of telecommunications?
Optical fiber is a network of cables made using glass fiber. Which if connected with the world of telecommunications, optical fiber itself means that the cable is used for directed transmission media (Wireline) for the sake of transferring data flows in computer networks. Without this, it is possible that the message you send from the cellphone never reaches the person you are trying to reach.
As already said that fiber optic cable is made of glass fiber with several layers of which have their respective functions. In addition, there are also components in the fiber optic cable such as insulators or coatings with various colors in one cable.

One strand of optical fiber is about the diameter of a human hair

By niveksuhail
As the saying goes, one strand of optical fiber is about the diameter of a human hair.CORNING It’s an amazing idea. Now, copper wires—sometimes called “twisted pair” because they are made of pairs of strands of copper twisted around one another—also carry data and telephone signals to homes and farms in much of rural America. But because of the characteristics of copper as a transmission medium, signals that travel over copper doesn’t have the extraordinary frequency range that light signals do, are subject to interference from other signals, and in general, degrade very quickly over more than a short distance. That’s why if you have a copper-wire DSL (digital subscriber line) subscription, you have to be very close to the phone company’s “central office” to get a download signal into your house. A DSL house is connected to a copper wire, not a fiber-optic cable. fiber optic installer salary Not only can light travel over fiber for hundreds of miles with little attenuation (im...

Design of the checklist of optic fiber network

By niveksuhail
The support person should also be involved to the point that he can answer most questions. You may even have more technical knowledge about the project, but you cannot have full authority to make decisions. In large projects, this person may be the one who keeps the documentation and the schedules, the one who keeps track of purchases and deliveries, permits, subcontractors, among other things, while the project manager plays a more role Practical and active Design of the checklist Planning a project is essential for it to be successful. The best way is to prepare a checklist before beginning the design process. The list below is exhaustive, but each project will have some unique requirements that will be it's own and should be added. It is not necessary that all steps be performed in a series. Some can be done in parallel to reduce the design time of the project. During the design of a project, the designer must communicate with several people and companies. Therefore contact...
