Fiber optic
Fiber optics is a technology that has revolutionized data transmission. It allows data to be transmitted around the world almost instantly – using light rather than electrical impulses.
Yes, you heard right - light, which travels at 300,000 kilometers per second.
But what's behind this technology? Why is fiber optics better bahrain telegram data than copper cables? And how has it changed the future of the internet? Let's find out.
How does fiber optic work?
How does fiber optics work?
Fiber optics is a cable made of very thin strands of glass or plastic that can transmit light signals over vast distances.
The principle of operation of optical fiber is based on the phenomenon of total internal reflection. When a light signal enters the central part of the fiber, it is reflected from the internal walls and continues to move without significant loss of energy.
This allows the signal to be transmitted over tens or even hundreds of kilometers with minimal distortion. Fiber optic cable consists of three main layers:
The core is a thin glass or plastic thread through which the light signal moves.
The cladding is a layer that reflects light, trapping it within the core.
