Identifying the cable link from the distribution frame microcable Pro can also provide office/room recognition, which can provide cable Direction recognition when adding, moving, and changing office sites. It helps identify the position of cables on the distribution frame and makes it easy to test and file twisted pair wires and coaxial cables. Audio function tracking and positioning

Overview Verification-check whether the bandwidth of the existing cabling system supports voice, 10/100, VoIP, or Gigabit Ethernet Fault Diagnosis-shows why the existing cabling system cannot support network bandwidth requirements, for example, there is a crosstalk at 11 meters) Search-detect the device connected to the other end of the cable and display the device configuration speed/duplex mode/line p

Detailed description of cable tester test parameters

Currently, the most widely used network cabling system is a twisted pair cabling system. Among them, the mainstream choice is a system with over 5 categories or higher performance. For cabling systems, the most basic test conducted by the installer is to use the connectivity tester to verify the end-to-end connection of the link. These testers provide complete wiring diagram tests, using TDR technology to m

the signal emits locally and is measured remotely. Fext is not very valuable in itself. Because the fext is influenced by the length of the cable link, the signal intensity including crosstalk will be affected by the attenuation after the signal source is emitted. It is also the reason that measuring the equivalent distal crosstalk (elfext) is more meaningful. The effect of attenuation is considered in the elfext result, so this parameter is more pr

Fluke Networks (Fluke Network) has launched an ethernet cable tester "DTX-1800", in addition to the widely used "5e" line, it can also be used to detect "6" and "7" lines with better transmission characteristics. You can check whether the cables used as the measurement object meet the corresponding specifications. The testing frequency is up to 900 MHz. Reduce th

Through rapid network search and fault diagnosis, elasticsearch can quickly find the cause of Wired/wireless network faults to ensure the normal operation of the network. It helps you optimize you

, after the force to hear a slight "Snap. As shown in, after the wire is pressed, all the pins protruding from the outside are pressed into the crystal and inside the head, and the plastic buckle at the bottom of the crystal head is also pressed on the gray protective layer of the network cable. Network cable

gently pull the network cable and the crystal head to see if it is pressed tight. It is best to press it once more. The most important thing is to pay attention to the correct pressure position.                   So far, this RJ-45 head is better. Follow the same method to create the crystal head at the other end of the twisted pair wire. Note that the core line sequence must be the same as that at the oth

Preparations for building a dormitory Network: Prepare a network cable

. Here, the author reminds readers that when using the HUB, switch, and other collection line equipment, these two standards cannot be mixed. When the dual-host interconnection does not use a hub, the T568A standard must be adopted first, and the T568B standard must be used on the other. According to regulations, the ports 1 and 2 of the network adapter send data, while the ports 3 and 6 are the receiving data pins. 1, 3, 2, 6 line swap is mainly to e

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 measurem

MHz. The frequency range is increased. It is obviously inappropriate to use the previous test accuracy. Because the three-level precision testing standard is for the previous definition of the test bandwidth to the existing 250MHz frequency. The new 6a/EA-Level test requires an updated precision category to be differentiated, that is, enhanced Level IIIa ). Of course, for ISO Class FA, there is an enhanced Level 4 Precision Level IVa. Currently, the four-level precision category is less than 60

If the Hub does not have a dedicated-level connection port, or you cannot use a level-level connection port, you must use a MDI-X port level connection, then we can use a line to achieve the purpose, the line reference is as follows.

Later, I borrowed the network cable tester, and the white-green and green cables were not connected, however, this pair of lines at the 7 and 8 locations is a backup line, which does not actually work and does not affect network connections.
