coax to twisted pair

We may be unfamiliar with the practices and usage of twisted pair wires. For example, it is hard to remember how the standard wire head is implemented. It is also vague to know the cross Line (or direct line) used. Let's talk about some notes. Prerequisites 1. Twisted Pair pin position definition (the crystal head has

So how to master the quality of these media to ensure smooth transmission of information, you need to rely on the verification of the Cable Testing Instrument. In addition, more than 90% of the network faults are caused by cable link problems, but these problems can not be checked in the shortest time only by visual or multimeter. During network construction, you must test the cable using a regular tester. In general, the network card will not strike easily, most of which are network faults caus

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

The quality of twisted pair wires may affect the overall network performance during network construction. The connection of twisted pair wires between various devices is also very exquisite and should be connected according to specifications. This article mainly introduces the standard connection method of

In order to be able to adapt to the development of network technology, ISO/IEC has developed a series of wiring standards, the ISO11801 standard defines 5 types of cable bandwidth is 100MHz, the revised standard is discussed in the definition of 6 types of cable bandwidth is 200MHz, The bandwidth of the 7-type cable is 600MHz. It should be noted that the bandwidth (MHz) of the cable and the rate of data transmitted on the cable (Mbps) are two distinct concepts. Mbps measures the number of bits

At the plenary meeting of the Institute of Electrical and Electronics Engineers (IEEE) 802.3, IEEE approved a new generation of BASE-T interest solicitation request (CFI ). The next generation of BASE-T will enter the stage of the standard development research team, the future direction of research and development is to balance the twisted pair copper cabling to reach at least 40g or even G Ethernet speed (

How can network managers implement bandwidth-intensive applications on local area networks (LANs) when budgets are tight and must maintain existing network systems? The latest Ethernet technology, 1000BASE-T (Gigabit Ethernet on the five-type twisted pair) can help network administrators quickly improve the performance of your network in a simple and inexpensive way.1000BASE-T is an Ethernet technology that

I've seen a lot of people these days. There is a lack of understanding and misunderstanding on the various technical problems of twisted pair wires. To solve everyone's doubts and repeated questions, special writing this paste, I hope to learn more about the Super five-type twisted pair (wire) and its standards and ele

Cat5e and cat6 twisted pair wires have entered the stage of diversified products and diversified classification. When installing the cabling system, people may have to choose products of Category 5, Category 5, Category 5, or Category 6. For the verification test of the cabling system, the standards for on-site testing lags behind products on the market. as we all know, the testing standard is required for

throughput on the channel. Various installed cable models have been designed in the industry to measure the typical foreign crosstalk produced at these frequencies when multiple cables are bundled very close together. However, there are still many problems to be solved: Which wiring facility can handle this speed with reliable information transmission? How far does it support? Is it economical? A working group has been set up in the industry to check whether the implementation of 10GbE on coppe

The advantages of twisted pair wires for Video Transmission indeed enhance our confidence in using the twisted pair wires for video transmitter in the project. However, there are still some problems in the actual product purchase and wiring applications, summarized as follows: 1) In order to enhance the anti-interferen

Experience and facts tell us that the advantages of UTP transmission video really enhances our use of twisted-pair video transmitter in the project confidence, but in the actual product purchase and wiring applications, or there will be some problems, to its summary, as follows: 1 in order to enhance the anti-interference ability, use the shielding line Some friends have long been using coaxial lines for

Twisted pair has two methods, eia/tia568b standard and eia/tia568a standard.(1) Straight line: Both ends are connected in accordance with the T568B sequence standard, as shown below:B Standard: white/orange orange white/green blue white/blue green white/brown BrownA standard: white/orange orange white/green blue white/blue green white/brown Brown(2) Intersection line: A t568b line order standard connection,

Many people (including the author) think that 10 Base-T 10 m networks use four of the eight signal lines in the network cable, the 100 Base-t m uses all eight signal lines (or how fast ?). However, when the author recently used a 10 m direct connection method (switching between 1 and 3, 2 and 6, and shielding the other four lines) to connect the network cable, unexpectedly, it was found that the Network was being transmitted at a speed of MB, so I had to worry about it. So I checked a lot of inf

When testing the twisted pair cable, the possible problems are: the near-end crosstalk is not passed, the attenuation is not passed, the wiring diagram is not passed, and the length is not passed:1. Causes of inpass of near-end crosstalk may be:1) there is a problem with the endpoint;2) Short Circuit at the remote connection point;3) string pairs;4) External Noise;5) The performance of link cables and conne

There are two connection standards for RJ45 twisted pair wires: Standard 568B: White orange -- 1, orange -- 2, white green -- 3, blue -- 4, white blue -- 5, green -- 6, white brown -- 7, brown -- 8 Standard 568A: white green -- 1, green -- 2, white orange -- 3, blue -- 4, white blue -- 5, orange -- 6, white brown -- 7, brown -- 8 Currently, the 568B standard is used in the network. 10 M Ethernet cab

So how to master the quality of these media to ensure unimpeded transmission of information, it is necessary to rely on cable testing equipment verification. In addition, in the cause of network failure, more than 90% of the fault is due to cable link problems, but these problems are not only visual or multimeter can be in the shortest possible time to check out. In the process of building the network, we must pay attention to the use of the normal cable tester test. generally speaking, the ne

Shielding and unshielded wiring system is superior to the inferior, has been a hot topic in the field of integrated wiring. Prior to the advent of 10G applications, European users used more shielding cabling systems, while North American users used more unshielded cabling systems. With the advent of 10G applications, the situation has changed a lot. As recently as the author in the "2011 China Data Center Network and Wiring Peak Forum", many large manufacturers have indicated that i

to the Internet. In fact, many network faults are not caused by problems with network switches, routers, network cards and other devices, but by poor quality of Network cables, crystal heads, or socket modules. Network disconnection or slow speed is mostly caused by poor network quality and high impedance signal attenuation. In overcast and rainy weather, disconnection often occurs, most of which is caused by bad quality of metal connectors of crystal heads or network modules and mildew. Some m

During the construction and completion of the Integrated Wiring project, it is often necessary to check the quality of the wiring project. The construction quality of twisted pair wires bears the brunt. based on years of experience in design and construction, summarize a set of practical detection programs and describe them to share with your peers. Pre-test check is indispensable Inspection includes appear
