There are two common ways to make network cable connectors.
A: orange white, orange, green white, blue, blue and white, green, brown white, brown.
b: green-white, green, orange-white, blue, blue-white, orange, brown-white, brown.
First, the principle of the splitter.
In the 10 100m Ethernet network we use, the transmission boundary is a Category 5 twisted pair. It is composed of 4 pairs of 8 cores. We only use 4 of them (2 pairs) for data transmission, and there are 4 (2 pairs) of wires left.
Therefore, we can use the remaining 4 wires as well as data transmission. In this way, the purpose of one network cable for two users to access the Internet at the same time is achieved. We don't generally use it that way.
After understanding the principle of the splitter, we should understand that the splitter made by the network center still allows users to enjoy the line alone, which is to divide the 8 lines in the network cable into two groups of lines to transmit data, so it will not affect the speed and bandwidth of the user's Internet access. This is fundamentally different from the distribution connector bought from outside. Therefore, it also does not result in users not being able to access each other on the same pair of splitters.
Second, the composition of the splitter.
Splitters are used in pairs. A pair of splitters is made up of two splitters.
A splitter consists of two heads, a module, and the two heads are connected to the module by twisted pairs. One of the crystal heads is arranged in blue, blue and white, brown and white, and brown 4 lines, which are respectively in the 1, 2, 3, and 6 slots of the crystal head. Another arrangement of the crystal head is that there are 4 lines of green-white, green, orange-white, and orange, which are in the 1, 2, 3, and 6 slots of the crystal head.
The other pair of splitters does the same.
Third, the use of splitters.
A splitter is required for each of the client side (dormitory) and the switch. If both ends of the network cable are crystal heads, connect the crystal heads on both sides to the modules of the two splitters. Generally, the longer splitter is placed on the user side, and the shorter splitter is placed on the switch side.
The two crystal heads of the splitter at the end of the computer room are plugged into the two ports of the switch, and the two crystal heads of the splitter at the user end are connected to the two users respectively.
Fourth, the precautions for the use of the splitter and the judgment of good or bad.
1. The splitter should be used only when there is no problem with the twisted pair (none of the 8 cores are disconnected).
2. A pair of splitters is equivalent to turning a twisted pair into two through wires. Therefore, the blue, blue-white, brown-white, and brown-white crystal head corresponds to the blue, blue-white, brown-white, and brown-white crystal head of the other end. Pay attention to this problem when using and testing the good or bad splitter.
3. The detection method of the splitter is the same as that of the ordinary twisted pair.

Press B's chromatography card line, take your second example, on the color card of the corresponding network cable, the blue and white network cable is stuck to the blue and white position, and the blue card is stuck to the blue position, but no clamp can be replaced with a utility knife, but be careful with the card.

There are two types of network cable interfaces that can be connected to the network, which are as follows:
A line order standard:
The line order is white-green, green, white-orange, blue, white-blue, orange, white-brown, brown.
Criteria for b line order:
White orange, orange, white-green, blue, white-blue, green, white-brown, brown.
Among them, the orange and white lines and orange are used to send signals; The green, white and green lines are used to receive signals.
Precautions for making network cables:
1. When peeling:
Cut the end of the thread with the trimmer edge of the crimping pliers, and then put the end of the wire into the stripping knife edge, let the corner of the wire head and the baffle, slightly hold the crimping pliers and rotate slowly, let the knife edge cut the protective rubber of the twisted pair wire, and pull off the rubber.
2. When sorting:
We can know that each pair of wires is intertwined, and 8 thin wires of 4 pairs must be straightened out when making a network cable.
3. When cutting evenly:
Straighten the thread as much as possible (do not wrap it), flatten it (do not overlap), squeeze it tightly and straighten it (close in one direction), and then use crimping pliers to cut the end of the thread flat. In this way, after the twisted pair is inserted into the head, each wire can have good contact with the pins in the head to avoid poor contact.
4. At the time of suppression:
Make sure that all the wires are in place, and check the wire sequence through the crystal head, you can clamp the RJ-45 head with crimping. The RJ-45 head is then pushed from the toothless side into the crimping plier groove, at which point the pliers need to be held firmly.

Eight first, you can connect it according to the A line or B line, and press the network cable.
-
If you want to connect the network cable yourself, it is recommended that you go to the Internet to find the relevant tutorial to take a look, and then insert the corresponding position according to the color of the network cable.
That is, according to the color of the row marked with the letter b, just insert the corresponding color of the network cable.

Cross line: that is, the network cable with the line sequence of one end of the crystal head A and the other end of the crystal head line sequence of B (i.e., 1-3, 2-6 pairs of inverted). It is suitable for interconnection between computers and computer network cards, or between network devices and network devices (such as the LAN port interconnection of two routers, or the common port interconnection of two switches).
Try it a few more times and you'll be familiar with it.

1. Divide the router into A and B, A is the main router, connect to the main router through the mobile phone, log in to the background management of A router with the WiFi signal, turn on the DHCP function of A router, and set the IP address pool range.
2. Turn on IP address filtering, or bind the IP address to the MAC address, which can prevent others from using the WiFi password key to crack the connection and WiFi signal.
3. As a secondary router, that is, a B router, you can log in to the router through the mobile phone connection first, and modify the default IP address of the router.
4. This is also to prevent the secondary router from being able to access the secondary router page because the IP address is the same when logging in to the primary router or the secondary router, and to turn off the DHCP function of the secondary router.
5. In addition, the address of the network is a static IP address, and the IP address is filled in by the main router, which is any IP within the DHCP IP address pool of the A router, pay attention to the A router DNS server and the alternate DNS server address.
6. The secondary router is set to a static IP, which can prevent the secondary server from having a conflict when obtaining the IP address and failing to obtain the network.

1. How to connect the network cable at home.
First of all, you need to prepare two wires, connect one of the wires to the port, and both sides need to be connected; Then connect the second cable, use it to connect to the computer, and then match, and it can be used normally. When setting, be sure to enter the address and password correctly, otherwise there is no way to enter the management page.
2. Precautions for purchasing network cables.
1. There are still many types of network cables, and before buying, it is best to understand them first to see which one will be more suitable to buy. If you need to split the line, it is recommended to buy a longer one, so that in the process of installation, there is no need to worry about not being able to reach it.
2. Be sure to remember to buy a network cable, and it should also match the withered cavity router, it is recommended that you buy it in sets, so that you don't have to worry about making mistakes. If you don't know anything about this, you can go to your local specialty store first, and the staff will give you a detailed introduction. If the quality is not good, it is not recommended to buy it, in case it suddenly breaks down when using it, it is very troublesome.
3. Precautions for installing network cables.
1. Before installing, you must remember to understand the interface, if you connect it wrongly, there is no way to use it normally, and you can go to a professional to help if you don't know how to wiring it.
2. It is best not to wrap the thread together, which will also affect its conveying speed.
