is similar to the RJ-11 telephone line in shape and exterior, but wider, due to the difference in size between the two (for 4 or 6-pin, RJ45 for 8-pin connectors ), obviously, the RJ45 plug cannot be inserted into the jack. In turn, it is physically feasible (the plug is smaller than the RJ45 jack), which makes people mistakenly think that the two should or can

RJ45 the definition and standards of the relevant provisions. 　　 RJ45 is a commonly used name, referring to the standardization of IEC (60) 603-7, using a modular jack or plug of 8 locations (8 pins) defined by the International connectors Standard. IEC (60) 603-7 is also the ISO/IEC 11801 International General cabling Standard Connection hardware reference standard. 　　 ISO/IEC 11801 standards regarding t

The RJ45 interface is typically used for data transmission, and the most common application is the NIC interface. RJ45 is a type of different joints; RJ45 head According to the order of the line there are two different ways, one is orange white, orange, green, blue, blue, white, green, brown, Brown, the other is green, white, green, orange, blue, blue, white, or

Topic OriginFor those who often work on multiple operating systems, using Windows as the host system with Vmware Workstation is already a standard Workstation. I personally traveled back and forth between Windows and Linux and used the notebook configuration as Windows 7 as the host, VMWare Workstation 9 to install the Virtual Machine CentOS and OpenBSD. Virtual Machine network connection is set

Information module jumper rules The patch cord rules of twisted pair cables are introduced above, because in enterprise networks, the cable head is not directly inserted into the hub or switch, instead, the network cable from the hub or switch is first connected to the information module and buried on the wall. This involves the core line arrangement sequence of th

We know that the cable is the basis of the network, if you do not well identify the use of the cable, you will not become a qualified engineer.The BNC cable is the copper shaft cable that we use for CCTV, which is used today as a signal input/output probe in an oscilloscope, although the appearance and the traditional cable are somewhat different, but the function is similar. It is mainly used in the network between the operator optical end machine to the router this link, is commonly known as t

Let's talk about the playing style and Tactics of RJ45 line sequence. The wiring standards of EIA/TIA define the line sequence 568a and 568b of the two twisted pair wires.568a standard:Green white -- 1, green -- 2, orange white -- 3, blue -- 4, blue white -- 5, orange -- 6, brown white -- 7, brown -- 8568b standard:Orange white -- 1, orange -- 2, green white -- 3, blue -- 4, blue white -- 5, green -- 6, brown white -- 7, brown -- 8 Note:568a:Green

Author: it.com. cnhttp: // www.ccw.com.cn 19:26:19 I want to comment (0) 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 transmitte

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

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

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

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

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

network cables for network cabling. They are divided into two 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 Conn

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
