• How to connect the Cat6 unshielded network cables?

  2021 / 04 / 12

  There is no difference between the connection method of the class unshielded network cable and the cat5e network cable, and the line sequence is basically no problem. There are two standard connection methods for network cables: 568A standard: green and white, green, orange and white, blue, blue and white, orange, brown and white, brown 568B standard: orange and white, orange, green and white, blue, blue and white, green, brown and white, brown The order of inserting the crystal head is: from left to right, in line order The biggest difference between Category 6 unshielded cables and Category 5 network cables is that there is a cross frame. When we connect the crystal head, after removing the outer skin, we need to sort the exposed white crosses and then sort the cores. Can use T568A/T568B line sequence for sorting In a wiring system, the wire sequence of the network cable should be standardized and unified, which is conducive to saving man-hours and multi-person wiring. If the network is blocked, it is easy to troubleshoot the situation. After sorting (T568B), the wire cores can be cut neatly. The outer skin of the network cable needs to be stuck into the crystal head. The crystal head is not easy to fall, and you can mark the position. The copper plate of the crystal head is facing upwards, the wire core is connected to the crystal head, and the crystal head is inserted into the cable clamp bayonet and pressed firmly. You will find that the six types of crystal heads are slightly different from the five types of crystal heads. The lines in the five types of crystal heads are lined up, and the lines of the six types of crystal heads are staggered up and down. At that time, because the five and six types of crystal heads were made by the RJ45 standard, the specifications and sizes were the same. However, the core of Category 6 wire is t

  Twisted pair (TP) is one of the most commonly used transmission media in integrated wiring projects. It is composed of two copper wires with an insulating protective layer. Twist two insulated copper wires to each other at a certain density, The radio waves radiated by each wire during transmission will be cancelled by the radio waves emitted by the other wire, effectively reducing the degree of signal interference. Twisted pairs in computer local area networks can be divided into two categories: unshielded twisted pair (UTP) and shielded twisted pair (STP): STP is wrapped with a layer of metal material to reduce radiation and prevent information from being eavesdropped on. At the same time, it has a higher data transmission rate, but the price is higher, and the installation is more complicated; UTP has no metal shielding material, only a layer of insulating rubber wrap, the price is relatively cheap, and the network is flexible. Except for some special occasions (Such as severe electromagnetic radiation, high requirements for transmission quality, etc.) In addition to using STP in wiring, we generally use UTP. The UTP currently in use can be divided into three types, four types, five types, super five types, six types, and super six types. The larger the type number, the newer the version, the more advanced the technology, the wider the bandwidth, and of course the more expensive the price. product structure: Conductor material/wire diameter: bare copper or stranded copper, ￠0.57±0.005mm (23AWG) Insulation material/wire diameter: polyethylene, ￠0.98mm±0.02mm Number of wire pairs: 4 pairs, two single-conductor double-twisted pairs form a pair. There is a high-density polyethylene cross isolation bracket in the middle of the cable to distinguish the four pairs of wires, which makes the balance performance of the pair more stable and can effectively prevent Perfo

• How to connect the network cable to the switch?

  2021 / 03 / 26

  Many small partners don`t know how to connect the switch to the network cable. As a professional network cable manufacturer, I will explain to you today: Switch means "switch" is a network device used for electrical (optical) signal forwarding. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is an Ethernet switch. Other common ones are telephone voice switches, optical fiber switches, etc. VLAN is a virtual local area network. By dividing the local area network into virtual network VLAN network segments, network management and network security can be strengthened, and unnecessary data broadcasting can be controlled. Break the geographical restriction in the shared network, and divide the subnet according to the management function. Switches of different manufacturers have different support capabilities for VLANs, and the number of VLANs supported is also different Plug the network cable into the switch. If it is an ordinary switch, regardless of incoming and outgoing lines, just find an interface and plug it in. In order to facilitate differentiation and maintenance, it is recommended that one port be connected to the incoming line and the outgoing line to any remaining port. If it is a network management switch, it needs to be configured according to the configuration. For example, port 0/0/1 is VLAN1 and configured for PC1, then PC1 can only be connected to port 0/0/1. So there are 2 ways of connection 1. When using a crossover cable, connect to the "common ports" of two switches (this line is also used to connect two computers directly to Zhuan) 2. One end of the standard line is connected to the switch "Ordinary port", the other end is connected to the "cascade connection port" of another switch (this line is also used to connect the computer to the switch) -*- The usual "switches" have cascading
