In this era of the industrial revolution 4.0, the existence of the internet is very important. Everyone is connected to each other into a unit that connects information between countries around the world. Some things you need to know right now are fiber optic technology and broadband internet.

Did you know that recently, fiber optic technology has become a hot topic of discussion because it is called the prima donna in the telecommunications world? However, many do not understand what the true meaning of fiber optics is and what is its relation to the industrial revolution 4.0?

Fiber optic technology is a transmission line or a kind of cable, made of glass or plastic that is thinner than a hair. This technology serves to transmit signals in the form of light from one place to another.

The light sources that are often used are lasers or LEDs. Fiber optic cable has a diameter of approximately 120 mm. The light in it does not come out because the refractive index in air is smaller than the refractive index of glass.

In addition, because the laser has a very narrow spectrum, the speed of this fiber optic technology is quite high. Thus, it is suitable for use as a communication channel. Therefore, it is not surprising that many large companies are using it.

More broadly, fiber optics are actually not only beneficial for companies, but also for the wider community. It is divided into two types, namely single mode fiber optic and multimode fiber optic cable. Single mode fiber optic cable has a single transmission to spread light.

Meanwhile, multimode fiber optic cable has many transmissions so that it can spread a lot of light at one time. The way it works is:

The source is in the form of an electrical signal which when at the transmitter is converted by an electro-optic transducer or known as a diode into light waves.
Then the light waves are transmitted through the fiber cable end to the receiver at the other end.
The optical signal receiver is converted by an optoelectronic transducer into a return signal.
