Ethernet Color Codes
การแนะนำ
Ethernet cables are used to connect devices within a network. They come in various colors, which may signify different purposes or specifications. Understanding the color codes of Ethernet cables is crucial for proper network installation and maintenance. In this article, we will explore the different color codes commonly used in Ethernet cables and their corresponding meanings.
Primary Colors
The primary colors used in Ethernet cables are blue, orange, green, and brown. These colors serve as a base for the entire color coding system. Each primary color represents a specific purpose or function within the network.
Secondary Colors
To further categorize Ethernet cables, secondary colors are used. These secondary colors are white, red, black, yellow, violet, pink, and gray. They are combined with the primary colors to create different cable specifications.
Tertiary Colors
For even more specific identification, tertiary colors are employed. Tertiary colors include light blue, slate, dark green, and light brown. These colors further refine the cable’s function or purpose.
Meanings and Purposes
Now, let’s delve into the meanings and purposes behind these color codes.
Blue – Typically used for straight-through Ethernet cables. These cables are commonly used for connecting computers or other devices to a network switch.
Orange – Primarily used for crossover Ethernet cables. Crossover cables are used to directly connect similar devices, such as two computers, without the need for a network switch.
Green – Often used for patch cables. Patch cables are usually used for short-distance connections, such as connecting devices within a server rack or patch panel.
Brown – Generally used for Multi-Pair Ethernet cables. These cables consist of multiple twisted pair conductors and are commonly used in high-density applications.
Combining Colors
Secondary and tertiary colors can be combined with primary colors to create different cable types or functions. For example:
– White and Blue – Typically used for voice and data applications, commonly known as Category 5e cables.
– White and Orange – Commonly used for Power over Ethernet (PoE) applications. These cables carry both data and power to connected devices.
– White and Green – Often used for Gigabit Ethernet connections. These cables are capable of higher data transmission rates.
– White and Brown – Frequently used for outdoor or direct burial Ethernet cables. They are designed to withstand harsh weather conditions.
บทสรุป
Understanding the color codes of Ethernet cables is crucial for proper network setup and troubleshooting. By knowing the meanings and purposes behind each color, network technicians can easily identify and utilize the appropriate cables for different applications. Remember to consult the manufacturer’s guidelines and standards when working with Ethernet cables to ensure proper installation and optimal network performance.
