In the early days of computer networks, copper cables were the primary transmission medium. Due to their low cost and good electrical conductivity, copper cables played a significant role in local area network construction. However, with the continuous growth of network data and the increasing demand for high-speed transmission, the limitations of copper cables gradually emerged. The limited transmission speed and bandwidth of copper cables, as well as their susceptibility to electromagnetic interference, have restricted network development to a certain extent. II. The Arrival of Fiber Optics Era

With the continuous advancement of technology, fiber optic technology has gradually emerged. Fiber optics, with its advantages of high bandwidth, resistance to interference, and long transmission distance, has become an ideal alternative to copper cables. The main component of fiber optics is glass or plastic that can transmit data in the form of optical signals, greatly improving the speed and efficiency of data transmission.

The introduction of fiber optics has made long-distance, large-capacity data transmission possible. Today, fiber networks have become an important foundation supporting emerging technologies such as big data, cloud computing, and the Internet of Things. With the promotion and application of new-generation communication technologies such as 5G and 6G, the importance of fiber networks is becoming increasingly prominent. III. Wide Application of Fiber Technology Nowadays, fiber optics are widely used in various fields. In home networks, fiber broadband has become a representative of high-speed Internet access. In enterprise networks, technologies such as fiber Ethernet have enabled companies to build efficient and stable internal communication networks. In fields such as industrial automation, healthcare, and transportation, fiber optics also plays an increasingly important role. IV. Future Outlook With the continuous development of technology, network cables will continue to evolve in the future. Transmission technologies with higher speeds and larger capacities will continue to emerge, bringing more possibilities for human society. At the same time, with the popularization of emerging technologies such as the Internet of Things and artificial intelligence, network cables will play an important role in more fields.
