inches. Therefore, data protection and isolation are very important tasks.
Countermeasure: multi-color solution
With the multi-color solution, technicians can intuitively view the plug or adaptation ports corresponding to each plug; Distinguish customers by simple color codes; use the color

General orange, orange, green, blue, blue, green, brown, white.
If there are only four wires, choose four cables. When the cables are made, press the four portals of the crystal hea
/brownStep 6: Cut bare twisted pair wires with scissors or diagonal pliers
14mm
The reason for leaving this length is to comply with EIA/TIA standards, you can refer to the relevant RJ-45 connector and twisted pair wire production standards. Finally, put each wire of the twisted pair into the pin of the RJ-45 connector in sequence, the first pin should put white orange lines, and so on
Step 7: Determine the twisted pair of each line has been correctly placed a

copper, bronze, copper clad aluminum, copper clad silver, four iron aluminum and so on. Among them, four iron and four aluminum are of the worst quality. Copper Clad aluminum and copper clad aluminum burned immediately in case of fire. After burning, the bronze was cut off immediately and it was also collectively referred to as copper clad copper. The outer layer was wrapped with a layer of oxygen-free copper, and the color and surface of the inside
based on North America's cable Fire standards UL and NEC (National Electrical Code), parts of Europe, the use of low halogen or low smoke halogen-free green cable standards.
Two. Halogen and halogen-free properties of wire and cable skins
In most parts of the world, electricity and telecommunications cables are curr
communication rate that can meet the bandwidth of M. Although its connection method also corresponds one by one, the color of each foot is fixed, specifically: 1st feet -- orange white, 2nd feet -- orange, 3rd feet -- green white, 4th feet -- blue, 5th feet -- blue white, 6th feet -- green, 7th feet -- brown white, 8th feet -- brown, it can be seen that the four core Cables of the network
affected.
After removing the gray plastic protective layer, you can see the 4-to 8-core wires of the twisted pair cable, and the colors of each pair are different. Each pair of core wires is composed of a colored core wire and a white core wire with only a few colors. The four full-color cores are brown, orange, green, and blue. Each pair of wires is intertwined. When creating a
quality levels defined by the International Electrical Industry Association for twisted pair cables.Super Five unshielded twisted pair is a cable that appears after improving some performance of the existing five types of shielded twisted pair, many performance parameters, such as near-end crosstalk, attenuation crosstalk ratio, return loss and so on have been improved, but its transmission bandwidth is still 100MHz.The super five twisted pair is als

1. Computer ←-→ Computer, said Peer-to-peer network connection, that is, between two computers only through a network cable connection

materials and printing clearly, and in most cases there are anti-counterfeit labels outside the carton.
2. Work on twisted pair case. The insulation skin of twisted pair wires should contain information such as the place of origin, implementation standard, product category, and cable length. Cat5 is the identification of Category 5, cat5e is the identification of Category 5, and cat6 is the identification of category 6 ".Products with uppercase lett
About the computer cable how to do is to engage in the network of the required courses, but also the most basic combat projects. Cable production methods There are many, we are here to create a simple RJ45 universal 8-pin cable production method.
We use the peeling function of the wire clamp to peel off the net wire,

Wiring is very important if you want to minimize network problems and bandwidth losses. When you try to design a network, there are some rules that cannot be violated-otherwise, you will encounter many computer communica
the connector is pulled. When using this protective sleeve, you need to put this rubber sleeve on the twisted pair cable before the crimping RJ-45 connector,.Step 8: Repeat steps 2 through 7 before creating the RJ-45 connector for the other end. Because the workstation is directly connected to the hub, the pin connection of the RJ-45 connector at the other end is exactly the same. After the completion of the connection lines at both ends of the RJ-45

After the completion of the connection lines at both ends of the RJ-45 connector both pin and color are complete ~ The connection method is applicable to the connection between the ADSL modem and the computer Nic.The direct connection network cable i

Here, we still use the "see" method to further discriminate, real 5 class/Super 5 line 4 on the core line white that should not be pure white, but with the pair of the core line color of the gray, this is mainly to facilitate the user in the production of Crystal head when the difference between the line pair.

caused by poor contact. When using this protective sleeve, it is necessary to insert the rubber sleeve on the twisted-pair cable before pressing the RJ-45 connector, as shown in the figure.
Step 8: Repeat steps 2 through 7, and then make the RJ-45 connector on the other end. Because the workstation and the hub are direct docking, so the other end of the RJ-45 connector pin method is exactly the same. After completion of the connector at both ends of
