Ethernet Color Codes
介紹
Ethernet color codes are used to identify different types of Ethernet cables and connectors. These color codes provide a standardized way to differentiate between different Ethernet categories, cable types, and wiring configurations. 在本文中, we will explore the various levels of Ethernet color codes and their significance.
Level 1: Cable Sheath Color
The first level of Ethernet color codes is based on the color of the cable sheath. Each Ethernet category has a different assigned color to distinguish it from other categories. These colors help network technicians easily identify and differentiate between Ethernet cables. The commonly used colors for different categories are as follows:
– Category 5e: Blue
– 類別 6: Green
– Category 6a: Orange
– 類別 7: Red
Level 2: Connector Boot Color
The second level of Ethernet color codes is represented by the color of the connector boot. The connector boot is the protective casing at the end of the Ethernet cable that holds and secures the connector pins. This color coding is particularly useful when connecting multiple cables in a patch panel or switch. The color of the connector boot provides an additional visual cue to identify the purpose or destination of the cable. The commonly used colors for connector boot coding are:
– Management Network: Blue
– Voice Network: Gray
– Data Network: Green
– Video Network: Yellow
– Wireless Network: Orange
Level 3: Wiring Configuration Colors
The third level of Ethernet color codes refers to the colors used for individual wire pairs within the Ethernet cable. Ethernet cables typically consist of four twisted pairs of wires. Each pair is color-coded using two different colors. These color combinations aid in proper termination and identification of the wires during the installation process. The standard color combinations for wiring configurations are:
– Pair 1: Blue and White-Blue
– Pair 2: Orange and White-Orange
– Pair 3: Green and White-Green
– Pair 4: Brown and White-Brown
結論
Ethernet color codes play an essential role in the networking industry. They provide a standardized system for identifying and differentiating between various Ethernet categories, cable types, and wiring configurations. By adhering to these color codes, network technicians can ensure accurate and efficient installation and troubleshooting processes. Understanding the significance of Ethernet color codes is crucial for anyone working with Ethernet networks.
