From kilobyte to mega. Anyone who remembers the noise and, above all, the speed, or lack of it, of the internet with a dial-up connection, is impressed by the speed of browsing with current technologies. What used to take minutes and hours to download today is done almost instantly. And that changed the digital life of many Brazilians.
According to the German company Statista, Brazil occupies the 5th place in the world ranking of countries with the highest number of internet users. There are more than 165 million users, second only to China (1 billion), India (658 million), United States (307 million) and Indonesia (204 million). But in addition to browsing speed, other characteristics of this internet model influenced the choice of use by the Brazilian consumer.
“Without electromagnetic interference and at high speeds, optical fiber is today the most cost-effective technology, as it also provides greater security, is more durable and does not depend directly on electricity for its operation, being more ecological and sustainable”, he says. Moacir Leão, director of WZnet Internet Barreiras, a telecom company from Bahia.
To give an example of the technological evolution in the infrastructure, in a single optical fiber, which has the thickness close to a strand of hair, it is possible to transmit approximately 2.5 million telephone calls. To achieve a quality like this, the (common) copper cable would have a thickness of six meters in diameter.
Favorite of Brazilians
The 70% of internet contracts using this technology indicate that this model is accessible and popular in the country. “With optical fiber, it is possible to reach terabytes per second, from one point to another, allowing file exchange, downloads and use of different services simultaneously and in real time”, explains Leão.
In addition, optical fiber has great resistance to electromagnetic interference, since the propagation of light that occurs within these materials is not subject to interference from external electromagnetic waves. And with cables that are cheaper than copper conductors.
“Optic fiber is also used in extensive submarine cables, which allow thousands of information and data to be exchanged in milliseconds all over the planet”, adds Leão.
