I. Introduction

        In this era of network-connected world, the network has become a necessary tool for our life, work and study. Behind the network, there is something called "network cable", which is like a "bridge" to the network world. Another type of equipment called "Fiber optic cable" is a tool that has played an important role in the field of high-speed network communications in recent years. Let's understand and compare the differences between these two devices and their applications.

Fiber optic cable and network cable

II. Network Cable Introduction

        2.1 Definition of network cable: A network cable, also known as an Ethernet cable, is a cable used to connect devices in a computer network, such as computers, routers, and switches. They transmit data over copper wires and are widely used in homes and businesses due to their low cost and easy installation.

        2.2 Types of network cables: The main types of network cables are Cat5e and Cat6. Cat5e is an enhanced version of Cat5 network cable, which can provide higher data transmission rate, generally up to 1 Gbps (gigabit per second), and compared with Cat5, Cat5e has been optimized in preventing electromagnetic interference. The Cat6 network cable is a more advanced Ethernet cable, which can provide a data transmission rate of up to 10 Gbps, but this needs to be under the condition that the length does not exceed 55 meters, and the cable structure of the Cat6 network cable is relatively complicated. Good anti-electromagnetic interference design.

        2.3 Application of network cable: Due to the low cost and easy installation of network cable, it is mainly used in small-scale network connections such as offices, schools, and homes to provide stable network connections for computers, printers, routers and other devices.

III. Introduction to fiber optic cable

        3.1 Definition of fiber optic cable: fiber optic cable is a new type of data transmission medium, which uses optical signals for data transmission to replace traditional copper wires. Due to the fast speed of light and strong ability to resist electromagnetic interference, the transmission speed and stability of optical fiber lines are significantly better than network cables.

        3.2 Types of fiber optic cables: There are two main types of fiber optic cables, single-mode fiber and multimode fiber. The core of single-mode fiber is very thin, allowing only one beam of light to propagate in it, so it can transmit longer distances, and is usually used for long-distance communications, such as cross-city or cross-border. The core of multimode fiber is thicker, which allows multiple beams of light to propagate in it at the same time, so it is better in short-distance transmission, and is often used for network connections in buildings or cities.

        3.3 Application of optical fiber lines: Due to the high speed and long-distance transmission capabilities of optical fiber lines, it has been widely used in many occasions with high bandwidth and long-distance transmission requirements. Such as broadband Internet services, telecommunication networks, cable television, data centers, etc.

IV. Comparison between network cable and fiber optic cable

        4.1 Transmission speed: The transmission speed of the optical fiber cable is much higher than that of the network cable, which can reach the level of Gbps or even Tbps, while the network cable usually can only reach the speed of tens of Mbps to 1Gbps.

        4.2 Transmission distance: Fiber optic cables can be transmitted without loss within tens of kilometers or even hundreds of kilometers, while the transmission distance of network cables is usually within 100 meters.

        4.3 Anti-interference: Optical fiber cables are hardly affected by electromagnetic interference, while network cables may be interfered by nearby power supplies and electromagnetic equipment.

        4.4 Cost: Although the transmission capacity of fiber optic cables is better than that of network cables, they are also more expensive. It includes not only equipment costs (fiber optic cables, optical modules, etc.), but also installation and maintenance costs.

        4.5 Ease of use: Since optical fiber cables require special equipment and technology for installation and maintenance, their ease of use is worse than that of network cables.

V. Application of fiber optic cables and network cables in modern technology

        5.1 Broadband Internet: Fiber optic cables and network cables are widely used in home and commercial broadband Internet. Typically, network cables are used to connect devices in the home to the router, while fiber optic cables are used to connect the entire home or office to the Internet service provider's network.

        5.2 Data center: Since the data center needs to process a large amount of data, it has high requirements for the speed and stability of the network. In such an environment, fiber optic cables are often chosen. At the same time, in order to ensure the connection between the internal equipment of the data center, some short-distance optical fiber lines are also used.

        5.3 Telecommunications: The telecommunications industry needs to provide high-speed data transmission over long distances, so fiber optic cables are the first choice for the telecommunications industry. Fiber optic lines play an integral role in services such as long-distance telephone calls, television broadcasting, and broadband Internet access.

        5.4 Other industries: In fields such as medical care and education, optical fiber cables and network cables also play an important role. For example, in telemedicine and online education, they provide high-speed and stable network connections, enabling these services to better serve the society.
