What is the network cable interface on the wall at home?

Ethernet cable interface on the wall of the home.

It is an RJ45 socket.

The RJ45 socket consists of a panel, an information module, and a back box.

Information module with twisted pair.

Terminations are available in either T568A or T568B configurations.

The household module adopts the T568B connection method. The order of the network cables is: orange-white, orange, green-white, blue, blue-white, green, gray-white, gray.

In order to facilitate the user's plugging and installation, a 45° bevel angle can be used. To achieve this, a 45° beveled panel is added to the standard module.

There will also be an RJ11 interface on the home socket panel, which is more than the RJ45 interface.

Slightly smaller, mainly used to connect ** cables. It should be noted that the RJ11 interface is 4 or 6 pins, while the RJ45 is an 8-pin interface, so the RJ45 plug cannot be inserted into the RJ11 interface, and vice versa, the RJ11 plug cannot be inserted into the RJ45 interface.

Place the router connected to the main line of the home at the assembly point of the network cable connector in each bedroom. This place is generally in a multi-** box, and then plug the connector in each room into the router after making the crystal head, if which bedroom is more commonly used, then connect a router in which bedroom. The IP of this router cannot be the same as the IP address of the router in the multi** box, and this router is set to automatically obtain IP mode, so that the lack of weak wireless signal in individual bedrooms can be solved.

The circular network cable interface on the wall of the home is the FC interface, and the optical fiber of the FC interface is not directly connected to the computer, it is connected to the router, and then the router is connected to the computer through the network cable. To use the FC interface, you need to purchase a special FC-PC fiber optic cable.

The fiber line style is as follows:

The FC interface is a standard form of optical fiber interconnection, and other common types are ST, SC, LC, and MTRJ. FC was developed in 1988 to improve the transmission bandwidth of the hard disk protocol, focusing on the fast, efficient and reliable transmission of data.

By the end of the 90s of the last century, FC SAN began to be widely used on a large scale.

The standard RJ45 interface is an interface with 8 metal contacts.

Summary. Can the network port on the wall be used directly 1. Whether the network port on the wall can be used directly needs to be tested. First of all, we need to take a look at the size of the network port, if the diameter of the network port is relatively small, then it is likely to be * line, can not be used directly.

If the caliber is relatively large, then it means that it is a crystal head network cable, which can be used directly. 2. There is also a detection method, which is to find a network cable to insert in the network port, and then connect to the computer for a test, if the computer can be used, then it means that this network port can be used directly, but usually, the other end of the network cable in the wall needs to be connected to a router or switch before it can be used.

Can you use the network cable interface on the wall at home when you plug it in?

Excuse me, but please go into more detail?

Find the network panel interface of each room, check whether there is a network cable, if there is no wire, you need to buy a network cable to penetrate from the embedded pipe, it is recommended to choose a Category 6 network cable and a Category 6 crystal head. When the original network cable is not replaced, it is necessary to calibrate the cable with a multimeter, peel off two cores of the network cable and short-circuit it, and use the diode file of the multimeter in the entrance box to find the short-circuited wire, find and mark the room.

Number of interfaces = Number of rooms + 2, for example, if there are 8 rooms, the switch must have at least 10 ports, and the switch with 16 ports is selected. The optical box switch is plugged into the network cable of all rooms, and the extra 2 ports of the switch are connected, 1 port is connected to the Gigabit port of the optical modem, and 1 port is connected to the wireless router as a standby.

If you have an Internet, you can use it by opening the socket and connecting it with a network cable.

It's okay to buy a port cable, and there are all kinds of meters.

Here's how:

1. First of all, pull out the twisted pair cable from the network cable cassette, leave the wire end about 40cm, and then cut off the excess wire. Then use a stripping tool to remove the outer skin of the remaining stranded wire from the bottom 10cm of the double friend's manuscript.

2. After peeling off the outer skin, separate the core of the twisted pair wire according to the color, be careful not to be reckless, and then disassemble the corresponding wire when it is pressed into the binding post in advance. According to the color code on the information module one-to-one correspondence, the line sequence mode should be uniformly adopted, in case of chaos, it will lead to network failure. Then the stripping position is parallel to the rear end face, the two hands slightly unscrew the twisted pair, and then press the wire into the corresponding trunking.

3. When all the wires are pressed into the corresponding trunking and rolled, then use the wire punching tool to press each wire core into the trunking. It is necessary to pay attention to whether the groove presses the core in place, and it cannot be crooked, otherwise it is very likely that the mouth of the metal clip will be opened, resulting in the ability to bite, and the wire post is easy to be crooked and cannot be repaired, and the module is equivalent to scrapping. If it is a new wire cutting tool, it is recommended to cut off the excess core during impact, or if it still does not work, impact it several times and then unscrew it by hand.

4. Finally, connect the dust sheet with the binding post, and then install the module that has been laid on the information panel, and the network cable port will be installed. Remind everyone to pay attention when wiring, so as not to cause unnecessary losses to the module if the wiring fails.

Precautions are required for home network cable connection:

When connecting the network cable, you need to remove the outer skin, and you must control the force when removing it, otherwise the core may be cut. In addition, the length of the parallel core should also be controlled, not too long, otherwise it will lead to interference between the cores, which will also have a greater impact on the communication efficiency. However, if the core is relatively short, there is no way to contact the metal piece of the crystal head, and there may be poor contact, so it is best to control its length within it so as not to have some impact.
