From the widespread deployment of 5G networks to the booming growth of cloud computing, artificial intelligence, and the “East Data, West Computing” initiative, the fiber optic communication industry, propelled by technological innovation, fueled by market demand, and bolstered. Fiber-optic communication is a form of optical communication for transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred. Fiber optic communication, as the cornerstone of modern communication technology, is increasingly asserting its indispensable role in the digital economy with its unparalleled transmission capabilities. From the widespread deployment of 5G networks to the booming growth of cloud computing. This article aims to highlight how advancements in optical fiber technology is enhancing transmission line performance and reliability in consumer electronics, particularly in digital video transmissions. By incorporating 40 years of optical fiber development, we can see significant improvements in. When Charles K. Kao during the 1970's went around the globe showing the feasibility of using optical fiber for telecom, he probably never imagined that he would be awarded the Nobel prize in physics, and that this media would be crucial for communication over the following decades. But how can we. 1Duhok Polytechnic University, Duhok, Kurdistan Region, Iraq.
