". The cable's two head presses in the RJ45 Crystal head separately according to the certain line order, this also is commonly said "the network cable". 1, what is T568A Standard and t568b standard? This is a series of two international standard lines developed by Super Five twisted pair to achieve performance index and unified wiring specification. (Can imagine: in the production of RJ45 Crystal Head, i

RJ45-type network cable plug, also known as Crystal Head, is widely used in LAN and ADSL broadband Internet users of network equipment between networks (called five-type line or twisted pair) connection. In specific applications, RJ45 plugs and network cables have two connection methods (line order), respectively called T568A Line sequence (Fig 1) and t568b line sequence (Figure 2). RJ45 type wire plug PIN

range should be measured. (2) near-end crosstalk +: Crosstalk is divided into near-end crosstalk and remote crosstalk (fext). The tester is mainly used to measure next. Due to line loss, the value of fext has little impact. The next loss measures signal coupling from one line to the other in an UTP link. For UTP links, next is a key performance indicator and the most difficult to accurately measure. As the signal frequency increases, the measurement difficulty will increase. Ii. cat5e uns

Preparations for building a dormitory Network: network cable production is a physical activity. Introduction of some common network cable knowledge, network cable production RJ-45 line production: First prepare the tools we need: Pressure clamp. ◆ Preparations for establishing a dormitory Network: First extract a short line and then peel off the outer skin (the length is about 1.2-1.3 cm ); ◆ Reverse winding of twisted pair wires based on Cabling Standards. The current wiring standards include

RJ45 network cable plug, also known as crystal head, is widely used in the connection between network cables of LAN and ADSL Broadband Internet users. Network clamp and wire measuring instrument will be used during the production process. ▲Figure: crystal head ▲Figure: Network clamp and wire Measuring Instrument In specific applications, RJ45 plug and network cable have two connection methods (line sequence), called T568A line sequence and

Broadband router Broadband routers play the role of shared gateways in the network, providing shared Internet services for computers in the network. At present, the market at home 4 Broadband router product prices are uneven, the general needs of the home network only need to buy a hundred or so products to meet, you can choose some of the market word-of-mo

5 cents to build your own Throwing Star LAN Tap Cause: The WEB "Wang" was boring to write PHP code at home on weekends. I was thinking about something interesting. I saw Throwing Star LAN Tap, but I didn't have time to play it, eager to open a treasure to get a back, a search will be dumb, a 1, 2 hundred dollars. When I buy a pair of trousers as silk, I think 100 yuan is a little too much. How can I spend money. It was quite easy to get one by yourself. Analysis: First, let's look at our analysi

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.

test of the wiring diagram verifies the connection relationship between the two ends of the line and the core of the RJ45 plug. In terms of contact points, the two Connection Methods T568A and T568B are generally followed. There is no difference in performance between the two methods, but the same method must be used for construction in the project. Wiring Diagram faults include open circuit, short circuit

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 standar

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 rig

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 corresp

failures are connected to the physical cabling, the production of network cable and the method of Plug and pull are closely related to the performance of network transmission. For example, if the physical connection cable we use is not manufactured according to the T568A Standard and the T568B standard, then the Internet signal is transmitted on the cable , it is easy to be disturbed by the outside world,
