machines. However, as machines become more powerful, wire density becomes critical, thus making optical fiber an alternatives source.
The usage of optical fiber in the telecommunications industry has grown a few decades ago. Today, many industries particularly telecommunications industry chooses optical fiber over copper wire because of its ability to transmit large amount of information at a time. Besides that, optical fiber could provide more advantages in this industry and this will be discussed further in this paper.
The first section of this paper will discussed about the principle and mechanism of optical fiber telecommunications, and the second section will discuss about the applications and advantages of optical fiber in telecommunications before ending with a conclusion.

Principle and Mechanism of Optical Fiber:

The principles and mechanism of optical fiber in telecommunications could be very complicated if there no basic understanding of optical fiber. ...

fibers cable in telecommunications network can be divided into two classes based on their modal properties. They are single-mode fiber and multimode fiber. Single-mode fiber has a smaller core than multimode fiber. It only allows one signal to transmit at a time. As for multimode fiber, it has a much larger core than single-mode fiber, allowing hundred of signals to pass through the fiber simultaneously. From what we have just discussed, it may seem that multimode fibers carry more information than single-mode fibers, but in reality, single-mode can keep every light pulse over a longer distance because its transmission of dispersion or degradation is very small, allowing it to have a ...
