Network World's Invisible Thread: Understanding the Types and Functions of Network Cables In today's digital era, the internet has permeated every aspect of our lives. And in this vast network world, there is an important component hidden - the network cable. These small wires play a crucial role in our information transmission and connection. Today, let's take a deeper look into the types and functions of network cables. Types of Network Cables: 1. Category 5e Cable (Cat 5e) Cat 5e is one of the most commonly used types of network cables. Its main advantages are stability and high-speed data transmission. Due to its excellent electrical performance and stability, Cat 5e is widely used in local area networks, campus networks, and broadband communities. 2. Category 6 Cable (Cat 6) Compared to Cat 5e, Cat 6 cables offer faster transmission speeds and are more suitable for Gigabit networks. With finer wire cores and more advanced manufacturing processes, it can better resist electromagnetic interference, providing high-speed network connections for large businesses and office environments.

3. Fiber Optic Cable (Fiber)
