Basic structure of Ethernet cable
Let me introduce you to the basic structure of the Ethernet cable and the functions of each component:
Physical structure of Ethernet cable:
- Conductor
- Composed of copper wires or copper-clad steel wires, responsible for signal transmission
- Insulation
- Common materials include PVC, polyethylene, etc., which provide electrical insulation
- Tear Tape
- Helps peel off the outer sheath for easy installation
- Shielding
- Made of copper braided mesh, aluminum foil and other metal materials to provide electromagnetic shielding
- Jacket
- Usually made of PVC, providing mechanical protection and UV resistance
The role of each component in the Ethernet cable:
- Inner core
- Responsible for the transmission of Ethernet signals and ensuring signal quality
- Tinned copper wire is usually used to improve conductivity and oxidation resistance
- Insulating layer
- Isolate the inner core from the external environment to prevent short circuit and leakage
- Material selection should consider flexibility, wear resistance and other characteristics
- Shielding layer
- Isolate internal signal lines from external electromagnetic interference to improve anti-interference performance
- Single-layer or multi-layer shielding design can be used to meet different needs
- Outer sheath
- Provide mechanical protection to prevent cables from being squeezed, torn, etc.
- Also has UV protection, anti-corrosion and other functions
In short, the basic structure of an Ethernet cable consists of an inner core, an insulation layer, a shielding layer and an outer sheath. Each component plays an important role. Only when these components work in harmony can the reliable transmission of Ethernet signals and the service life of the cable itself be ensured.
Standard appearance characteristics of Ethernet cables
Let me introduce to you the standard appearance characteristics of Ethernet cables, as well as their corresponding cable types and application scenarios:
Dimensional features:
- The diameter size is usually between 4-8mm, the thinner one is 4-6mm, and the thicker one is 6-8mm.
- Thickness size determines the mechanical strength and bending performance of the cable.
- Thinner cables are more suitable for small wiring spaces, while thicker cables are more durable.
Color characteristics:
- Common colors include gray, blue, black, yellow, etc.
- Different colors usually correspond to different types of Ethernet cables:
- Grey – Standard Ethernet Cable
- Blue – Ethernet cable with PoE power supply
- Black – Industrial Ethernet Cable with Enhanced Shielding
- Yellow – wear-resistant Ethernet cable for harsh industrial environments
Connector style:
- RJ45 standard network plug is the most common connector form.
- There are also some industrial applications that use stronger M12 or M8 connectors.
- Some cables also have plastic sheaths or metal shells to enhance anti-interference and protective performance.
Application scenario analysis:
- Standard gray Ethernet cable is suitable for ordinary office and home network environments.
- Blue PoE cable is used for network devices that need to transmit data and power at the same time.
- Black industrial Ethernet cable is used in strong electromagnetic interference situations such as factory workshops and power plants.
- Yellow wear-resistant cables are suitable for network deployment in harsh environments such as outdoor and underground.
In short, the appearance characteristics of an Ethernet cable can reflect its cable type and application scenarios. In actual selection, the appropriate size, color and connector form need to be selected based on specific environmental conditions and network requirements.
Tips for identifying Ethernet cables
Let me introduce to you how to identify the transmission performance and applicable scenarios of Ethernet cables based on their appearance characteristics:
Judge transmission rate and distance based on cable appearance:
- The thicker the cable diameter, the higher the transmission rate and distance it usually supports.
- The diameter of standard Ethernet cable (Cat5e/Cat6) is generally 5-6mm, supports 1000Mbps, and the maximum distance is 100 meters.
- Industrial Ethernet cable (Cat6a/Cat7) is usually 6-8mm in diameter, supports 10Gbps, and can reach 100 meters.
- Fiber optic Ethernet cables are smaller in diameter but can support high-speed transmission over longer distances.
Identify the different types of Ethernet cables:
- Straight-through cable:
- The line sequence at both ends is consistent and is used to connect network devices to devices.
- Crossover cable:
- The line sequence at both ends is reversed and is used to connect two network devices of the same type.
- Controller-device cable:
- One end is a standard RJ45 and the other end is an industrial connector for connecting industrial control equipment.
Tips for determining cable usage:
- Check the connector types at both ends of the cable to see if they are the same or different.
- Check the cable sequence arrangement to see if it is straight-through or crossed.
- Determine the correct use of cables based on device type and network topology.
Other identification points:
- Check whether there are markings on the surface of the cable, such as “CAT5e”, “CAT6”, etc.
- Measure the cable diameter and compare it with the above size range.
- If possible, you can use a tester to check the transmission parameters of the cable.
In short, by carefully observing the appearance characteristics of the Ethernet cable, including diameter, color, connector type, etc., you can roughly determine its supported transmission rate and applicable scenarios. This helps in selecting the appropriate cable type to ensure reliable operation of the network system.
