connected in t568b line order.When creating a network cable at ordinary times, if the network cable is not connected according to the standard, although sometimes the line can be connected, the interference between various lines within the line cannot be effectively eliminated, leading to an increase in the error rate of signal transmission, this affects the overall network performance. Only by building standards can we ensure the normal operation of the network and facilitate the maintenance w

instantaneous traffic, cumulative traffic and other traffic parameters, and then transmits the necessary data to the PLC through Modbus, after necessary processing by PLC, it is displayed on the PC for production and operation. The process is as follows:　　 Figure 1: Data Flow Direction of Traffic parameters Debugging process　　I. WiringA-B company contrologix, its remote I/O rack has a communication template, called mcm (Modbus conmminication model), that is, Modbus communication template.

computer that is connected to the Internet) should be placed in the direction of the Internet phone line, because the shorter the telephone line the better. 　　Two. LAN Cabling The first step is "Put the line", determine the network hub and the distance between each computer, intercept the corresponding length of the cable, and then the network cable pipe (PVC pipe). You can also walk directly along the wall without having to wear a tube. It should be noted that the length of the twisted pair

control and monitor the work of Phy. On the basis of MII, I later had the following: Rmii (reduced media independant Interface) Simplifies MII, with fewer signal lines than MII. Gmii (Gigabit media independent interface) Rgmii (reduced Gigabit media independent interface) Connection between PHY and RJ45 There are a large number of simulator devices on the phy, and Mac is a full digital device. The current IC technology can already integrate th

centers is more distinctive. Flexibility In a data center, the device can be configured with both the optical network card and the copper network card, and the number of two ports for different devices and specific applications does not have a definite value, this requires that the cabling product be flexibly configured according to specific requirements. Hybrid-Patch adopts a modular structure and can be divided into different modules, each module can be installed with a number of modules as n

). Bidirectional detachable copper cable distribution frame Speaking of RJ45 interface copper distribution frames, there is still a history. At the end of 1980s, when integrated wiring entered China, the transmission rate was very low and there were only three types of cables. Therefore, the wiring system had only 110 distribution frames, either a horizontal subsystem or a main subsystem, all use this system, mainly used together with the large log

-232, RS-422 and RS-485 standards only to interface electrical characteristics to make provisions, and does not involve connectors, cables or protocols, on this basis, users can establish their own high-level communication protocols. The most frequently used plug-ins we encounter in our actual work have three DB9 DB25 RJ45 plug-ins. The above three plug-ins can be used as serial port plug-ins, you can also switch between sockets through cables. Next w

1000base-x location. 2. MDI interfaceMDI is the interface between the PHY chip and the physical medium, the RJ45 interface is common. Hundred gigabit Nets, MDI four lines, two pairs of differential signals, only with the RJ45 1,2,3,6 line,. Gigabit Network, MDI altogether 8 lines, four pairs of differential signals, with the RJ45 8 lines again

I have seen a lot of articles to make Raspberry Pi into a wireless AP, but what I want to do today is to make Raspberry Pi into a NAT-enabled router, I did this because I was on a business trip to Holland and found my bambook unable to access the dorm WiFi, Perhaps because the dorm wireless router is the way to authenticate WEP, in short, not even. Later decided to use Raspberry pi+ Arctic Starlight Wireless router to solve the problem. Ideas:"Wireless Router"-----"wireless network card--raspber

Millet Notebook air can be directly plugged into the Internet network ? First look at the two-sided Millet notebook air interface, you can see only 2 USB 3.0 interface, 1 HDMI high-definition video interface, 1 standard headphone/mac interface, no other interface for the first time, as shown in the picture. Millet notebook Air Expansion interface diagram As can be seen from the above, the Millet notebook Air expansion interface is relatively small, not equipped with

This is a creation in Article, where the information may have evolved or changed. Background The story is this: The company system has a service is pdf2jpg (actually should be ppt2jpg, just ppt2pdf This step we use seven cow cloud service to complete. In the early days, we used the crontab to get the data that the database needs to be converted periodically according to the system load. So the QPS of this service is 1/60 QPS. Yes, you do not see the wrong is so low, but it is OK, after all, the

1, download the free section Assistant, install and run. Disk condition as shown in Figure 1, from the main interface you can see that the E disk has about 302GB,C disk only about 29GB, the following is a 10 GB free space from E disk to C disk to expand the C disk as an example: Figure 1 2, select e disk, click the right mouse button to choose "Allocation of free space" or on the left side of the partition operation to choose "Allocation of free space", as shown in F

. It can not be neglected that the SWS series of optical time multiplexing OTDM technology, optical soliton O-soliton technology and even optical Code Division multiplexing OCDM technology, but also hope to become members of the optical network family, but these technologies have not been out of the laboratory. Experts predict that the 4x40 GB/s systems implemented using OTDM will be first commercially available in ETDM's 160 GB/s. Two, one wavelength solution (SWS) 1. The evolution of SDH te

, a wider range of cat6a/classea copper systems, and more 10gbase-t-based networking devices to support the growth of 10G connections and gain more bandwidth capacity. As we all know, UTP copper cabling can often provide a more economical cost than optical fiber for 10gbase-t channels. Electronic devices used for 10GBASE-T are more complex than electronic devices used by 1000BASE-T, but they should be much cheaper than electronic devices 10gb/s fibre

/1KB = 0.5 rounding up = 11 * 100 = 100 Write capacity units DYNAMODB partition initial partition count calculationWhen the data is stored, DYNAMODB divides the table's items into multiple partitions and is supported by the SSD. The distribution of data is mainly determined by the partition value.The DYNAMODB service is solely responsible for the management of the partition, including the number of start table partitions and partition splitting.First we need to know that a partition in Dyna

multimode.The difference between Singlemode and multimodeGeneral manufacturers will be in the color of the pull ring to distinguish, for example: Black pull ring for multimode, Wavelength is 850nm, blue is the wavelength of 1310nm module, yellow is the wavelength 1550nm module, purple is the wavelength 1490nm module.Optical Module ClassificationXFP Optical ModuleSelectable wavelength: 850NM,1310NM,1270NM,1330NM,CWDM,DWDMRate: 10GXFP (Gigabit Small Form Factor pluggable) is a hot-swappable optic

network. In addition, on this layer, you can support cables and optical cables depending on the type of cabling you are using ). Unshielded twisted pair UTP) copper cable can be used for different purposes, in general, it contains an eight-pin RJ45 interface. A normal Ethernet copper network cable can be used to transmit electrical signals from one end to the other. A direct connection network is used to connect a pc to A vswitch, as shown in Figure.

for the overall performance of the network cabling system. I believe that the advantages of dedicated jumpers mainly include the following advantages: First, the electrical performance of the dedicated jumper is higher than that of the manual production product. Dedicated jumpers and self-made Jumpers are used to test the same cat5e cabling link. Generally, the channel performance difference is about 30%. Secondly, the dedicated jumper adopts the multi-core wire core (usually 8 cores) and dedic
