How to connect the network crystal head
In today's digital age, network connectivity has become an integral part of daily life and work. Whether it is home network cabling or enterprise network construction, correctly connecting the network crystal connector (RJ45 connector) is a key step to ensure stable network transmission. This article will introduce in detail how to connect the network crystal head, and provide structured data to help readers quickly master the skills.
1. Network crystal head connection steps
1.Prepare tools and materials: Requires network cables, RJ45 crystal connectors, crimping pliers, wire stripping knife and other tools.
2.Peel off the skin: Use a wire stripping knife to peel off about 2 cm of the outer sheath of the network cable to expose the 8 twisted pairs inside.
3.Arrange line order: Arrange the line sequence according to the T568A or T568B standard (common standards are in the table below).
4.Trim threads: Trim the wire ends neatly and insert them into the crystal head, making sure each wire touches the metal contact.
5.Crimp fixed: Use crimping pliers to press the crystal head to complete the connection.
| Wire sequence standards | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| T568A | Green and white | green | orange white | blue | blue and white | Orange | Brown and white | Brown |
| T568B | orange white | Orange | Green and white | blue | blue and white | green | Brown and white | Brown |
2. Common problems and solutions
| question | Reason | solution |
|---|---|---|
| The network is blocked | Wrong line sequence or poor contact | Recheck the wire sequence and crimp |
| Internet speed is unstable | The wire quality is poor or too long | Replace with high-quality network cable (category 5e or above recommended) |
| Crystal head loose | Incomplete crimping | Use professional crimping pliers for secondary reinforcement |
3. Precautions
1. The length of the twisted pair should not exceed 1.5 cm to avoid signal interference.
2. When crimping, make sure that the metal piece of the crystal head completely penetrates the wire sheath and makes good contact.
3. It is recommended to use a line tester to test connectivity to ensure that all 8 wires are connected.
4. Popular network technology topics on the entire network (last 10 days)
| hot topics | focus of discussion |
|---|---|
| Wi-Fi 7 technology progress | Practical applications of multi-link operation (MLO) |
| Fiber to the Home (FTTH) | Gigabit broadband penetration rate increases |
