How to connect two crystal heads to one cable
Many home renovations have only buried a network cable in the living room, followed by telecom broadband and IPTV. These two east-west lines are separate. Two network cables are required. Only the distribution line is processed. It may be necessary to divide one network cable. For two.
The network cable in the home is generally 8-core, the 100Mbps connection method uses 4 cores, the 1000Mbps connection uses 8-core network cable; the 100M network only needs 1, 2, 3, 6 four cores, two cores send data, two The core receives the data, and the remaining four cores can be used to connect to another network;
The network cable is divided into two groups and is divided into two groups, each group transmitting 100 Mbps network signals.
In the 100M network, only the 1, 2, 3, and 6 cores in the network cable are responsible for network signal transmission. Since the network cable generally has eight cores, one network cable can be divided into two four-core network cables. After a network cable is divided into two network cables, if you connect two computers, you need to plug the crystal heads in the routers or switches to connect to the Internet.
Option One
Our commonly used network cables generally use eight cores, but only the 1, 2, 3, and 6 cores are responsible for data transmission, so one network cable can be divided into two four-core network cables.
According to the 568B standard network cable, the four cores of white orange, orange, white green and green can be made into crystal heads according to the order of 1, 2, 3 and 6 lines, and the four cores of white brown, brown, white blue and blue will be used. The crystal head is made in the order of 1, 2, 3, and 6.
According to the 568A standard, the two ends of the network cable can be white green, green, white orange, orange, and the four cores are made in the order of 1, 2, 3, and 6 lines, and the white, blue, white, and brown are four. The core is made in the order of 1, 2, 3, and 6 lines.
After a network cable is split, it is equivalent to two four-core network cables.
After a network cable is disconnected, only two routers or switches can be connected to allow two computers to access the Internet at the same time. Since one network cable is equivalent to two network cables after splitting, only the two crystal heads after the split line are connected to the router or the switch, and the other two crystal heads are connected to the computer, so that two computers can be connected to the Internet at the same time.
Support one hundred megabytes of broadband after one network cable is divided
Since the four-core network cable supports only one hundred megabits of broadband at most, after dividing one network cable, at most, it can only support 100 Mbps network. If you use 100M and above fiber optic broadband, it is generally not recommended to use one network cable. In addition, the network cable is divided, there is interference, and there is still a certain gap between the network transmission quality and the single network cable.
Option II
Use the splitter and use a pair of splitters. If the office has already installed a network cable and only one network port, to realize the simultaneous networking of two computers or one connected computer and one connected set-top box, you can use the splitter, as shown below:
