the electromagnetic principle: it can be considered that the interference signals of the two signal lines are of the same phase and equal amplitude. After the two lines are combined, they both resist external interference and prevent themselves from interfering with others. Twisted Pair wires are commonly used.Most local networks use Unshielded Twisted Pair wires (UTP-Unshielded Twisted Pair) as the transmission medium for cabling. The network cable consists of a long Twisted Pair wires and

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 network cable, you must unbind, straighten out, and straighten the eight wires of the four pairs one by one, then,

types: shielded and unshielded. If it is used outdoors, The Screen Shield is better. Generally, it is enough to use non-shielded five-category cables in the room. Because no Screen Shield is provided, the cables are relatively soft, but their connection methods are the same. In general, there are four pairs of lines twisted together in the cat5e category and marked with different colors. Twisted Pair wires have two Connection Methods: EIA/TIA 568B standard and EIA/TIA 568A standard. T568A line

Twisted Pair wires have two connection standards: EIA/TIA 568B standard and EIA/TIA 568A standard. T568A line Sequence 1 2 3 4 5 6 7 8 Green, white, orange, white, blue, white, orange, brown, white, brown T568B line Sequence 1 2 3 4 5 6 7 8 Orange white orange green white blue white green brown white Brown Express CONNECT: Both ends are connected in the T568B line sequence. Crossover line: One end is connec

1. Shared Internet access (1) network connection If you want to add an additional computer to share the Internet with ADSL, You need to purchase two more NICs, one installed on the Internet access computer, the other is installed on the computer to be shared (hereinafter referred to as the client. We recommend that you purchase a 10/100 Mbps white adaptive Nic. It is worth mentioning that if the ADSL modem is an external Ethernet interface, there will be two NICs in the Internet access computer,

There are two international standards for the production of twisted pair wires: EIA/tia568a and EIA/tia568b. There are two main connection methods for twisted pair wires: straight-through cables and cross cables. Simply put, the straight-through cable means that both ends of the crystal head adopt the t568a standard or the t568b method at the same time, while the crossover cable is made of the t586a standard at one end of the crystal head, the other e

A lan is to connect individual computers or terminals using networks to exchange information and share resources according to certain protocols. Commonly used network cables include twisted pair wires, coaxial cables, and optical fiber cables. Twisted Pair wires can be divided into shielded twisted pair wires (STP) and unshielded twisted pair wires (UTP) based on whether they are added with the screen layer of a wire mesh ). Most local networks use unshielded twisted pair wires (UTP-unshielded t

repeater to expand the topological distance of the network. This is because signal attenuation occurs after long-distance transmission. The function of a repeater is to sort out the signals that have been degraded and become incomplete, re-generate a complete signal and continue transmission. A repeater is the predecessor of a general hub. A hub is a multi-port repeater. Take the hub in Figure 1 as an example. A hub generally has a BNC connector, an AUI connector, and an

RJ11 the definition and standards of the relevant provisions. 　　 RJ11 usually refers to the 6-position (6-pin) modular jack or plug. The connectors do not have international standards and are mentioned in the generic cabling standard. Also, this name is often used in the 4-pin version of the modular connector, causing confusion. 　　 In the generic cabling standard, there is no separate mention of ' RJ11 ', all the connecting devices must be 8 stitches. Therefore, RJ11 and

Integrated Network Cabling Standards include: That is, the T568A standard and the T568B standard. The line sequence described in T568A is from left to right: 1-white green, 2-green, 3-white orange, 4-blue, 5-white blue, 6-orange, 7-white Brown, 8-brown; The line sequence described in T568B standard is from left to right: 1-white orange, 2-orange, 3-white green, 4-blue, 5-white blue, 6-green, 7-white Brown,

straight-through cable means that both ends of the crystal head adopt the T568A or T568B connection method at the same time, while the crossover cable adopts the T586A standard at one end of the crystal head and the T568B standard at the other end, that is, 1 and 2 of A crystal head correspond to 3 and 6 of B crystal head, while 3 and 6 of A crystal head correspond to 1 and 2 of B crystal head. Others rema

cable production and hundred trillion different, the production method is as follows: 1 to the 3,2 to the 6,3 to the 1,4 to the 7,5 to 8,6 to 2,7 to the 4,8 to 5. For example: One end is: white orange, orange, white green, blue, white blue, green, white brown, Brown; The other end: White green, green, white orange, white brown, brown, orange, blue, white blue; T568B: Orange white, orange, green white, blue, blue white, green, brown white, brown T56

1, the production of network cable, the first is to prepare materials, tools, etc., we need materials, tools have a suitable length of twisted pair, a number of RJ45 crystal Head, a twisted pair of wire crimping pliers, twisted pair tester; 2, twisted-pair connection method has two kinds: normal connection and cross connection, the normal connection uses is the international Eia/tia 568B Standard, but the cross connection uses is the inte

through LED lights, do not worry about jumping the wrong port. Bulk jump, that is, you can first down the task, and then physical jump, you can also first batch physical jump, and then through the software alarm platform to confirm, eliminate the alarm confirmation connection. In addition, the intelligent jumper itself also has a certain detection function, once the jumper is broken by external forces, while affecting the detection circuit, immediately generate alarms.650) this.width=650; "titl
