**The Evolution of Network Cables: From Copper to Fiber** In the rapidly developing information technology today, network has become an indispensable part of people's daily lives and work. As the core component of network transmission, network cables have also experienced significant changes from copper cables to optical fibers. This article will detail this evolutionary process.

In the early days of computer networks, copper cables were the most common transmission medium. Due to their low cost, ease of production, and widespread application, copper cables were the first choice for network cabling for a long time. However, with the continuous advancement of network technology, the limitations of copper cables have gradually become apparent. For example, due to their high resistance, copper cables produce significant signal attenuation and interference during transmission, affecting transmission speed and distance.

With the development of optical communication technology, optical fibers have gradually replaced copper cables and become the main medium for modern network transmission. Optical fibers, with their advantages of high bandwidth, strong anti-interference ability, and long transmission distance, have quickly dominated the field of network cabling. The birth of optical fibers not only greatly improves the transmission speed and stability of the network but also provides strong support for the further development of network technology. Compared to copper cables, optical fibers have significant advantages: 1. High bandwidth: The transmission speed of optical fibers is far higher than that of copper cables, meeting the high-speed transmission demands of future networks. 2. Strong anti-interference ability: Optical fibers are not affected by electromagnetic interference, ensuring stable signal transmission. 3. Long transmission distance: The transmission distance of optical fibers far exceeds that of copper cables, making long-distance network cabling more convenient. 4. Environmental protection and energy saving: Optical fibers have low transmission loss, saving energy and material resources. In conclusion, the evolution from copper cables to optical fibers is an inevitable trend in the development of network technology. With the continuous advancement and expansion of optical communication technology, optical fibers will become the preferred medium for future network cabling. As new technologies such as 5G, the Internet of Things, and cloud computing rapidly develop, the demand for network transmission speed and stability will increase, highlighting the advantages of optical fibers even more. Therefore, understanding the evolution of network cables from copper to fiber is crucial for grasping the development trends of network technology.
