the DTX series cable certification analyzer launched by fluke is a high-tech test platform that can meet current requirements and face future technological development. By improving the performance of all links in the testing process, this innovative testing platform greatly shortens the time of the entire certification test. The test time of DTX series cable certification analyzer for CAT6 link is only 9 seconds, which meets the certification requirements of tia-568-c and iso11801:2002 standards for structured cabling system. All its products also have class IV accuracy, unmatched intelligent fault diagnosis ability, 900MHz test bandwidth, 12 hour battery life and fast instrument settings, and can generate detailed Chinese graphic test reports. It can be said that with the help of DTX series testers, you have the best tool to solve problems and are ready to face any challenges in the future

then, in the process of purchasing and using fluke DTX series cable certification tester, users may often encounter such problems because they do not know enough about the product. To this end, we focus on K 2016 and gradually summarize the following user concerns. We hope that through the following question and answer form, you can have a deeper understanding of DTX series products, and finally help you improve your product application skills and capabilities

question 1: which module does DTX need to use to test the optical fiber link according to the Gigabit standard

answer: the optical fiber Gigabit test standard includes 1000base-sx and 1000base-lx. 1000base-sx is used for multi-mode optical fiber, using 850nm wavelength VCSEL light source, 1000base-lx is used for single-mode optical fiber, and using 1310nm wavelength laser light source. Dt-gfm2 is required during the test. This module uses 850nmvcsel light source and 1310nm laser light source, just like the light source used in the actual switch, In this way, the test results are closer to the real application

question 2: can DTX test the optical power of 1490nm wavelength

answer: DTX or simpfiber does not support 1490nm, so it is impossible to test the optical power of 1490nm wavelength. To test the 1490nm wavelength, the tester must support the test of this wavelength. You can choose ahgg-g or sfpower meter

question 3: why is there a character "I" in front of some parameters in the result when DTX is used to test twisted pair

answer: "I" means information. This shows that in the selected test standard, this parameter is not used as the basis for passing or failing, and the test is not required. However, this parameter is also tested for the reference of testers

question 4: the permanent link adapter performance of DTX 5. What if the output result of the film tension tester decreases

answer: the typical service life of the plug of DTX permanent link adapter is more than 5000 times, so the adapter should be taken care of and protected when in use. As the number of tests increases, the performance of the adapter will decline. In this case, the permanent link adapter can be calibrated through the calibration operation to ensure accurate test results. It is recommended to calibrate the adapter at least every 6 months

question 5: what is the purpose of setting the benchmark for DTX

answer: the benchmark setting procedure can be used to set the benchmark of insertion loss and equivalent remote crosstalk test, while ensuring high accuracy test results. After the tester and intelligent remote are powered on, wait at least 1 minute before setting the benchmark. It is recommended to set the benchmark every 30 days

question 6: what kinds of standards are involved in the test? Which standard is high

answer: the test mainly involves three types of standards: application standards, link test standards tg=230 ⑶ 10 ℃, component standards. Component standards have the highest requirements, defining the performance and level of cables, connectors and hardware, such as ansi/tia/eia568-b.2; The link test standard requirements take the second place, defining the measurement methods, tools and processes, such as ansi/tia/eia568-b.1; The application standard requires a minimum of only one coat of varnish, which defines the properties of all elements required for a network, such as 100bast-t

question 7: what does the * sign mean in the test results

answer: * indicates that the test result value is within the accuracy range of the tester, which is very close to the accuracy of the tester. There are mainly two cases of test results with * marks: pass* and fail *. Pass* indicates that the test value is better than the standard value. If it has just passed, the link is qualified. Fail* indicates that the test value is lower than the requirements of the standard value. If it fails, it is an unqualified link

question 8: what indicators should be tested for coaxial cable link testing

answer: mainly test impedance, length, insertion loss (attenuation), resistance and transmission delay

question 9: what is the role of analog and digital signals sent by the line finder

answer: today's network devices use common mode termination for cables connected to their ports. While reducing the noise and series winding in the cable, this termination method will make it very difficult to detect the cables of these access network devices. Using simulation technology to locate a network without any identification will take a lot of time. Unlike analog technology, the digital signal of intelligent audio still has a strong amplitude under the common mode termination mode. The intelligent audio generator automatically generates audio on different cable conductors, which can quickly, effectively and safely locate a running network

question 10: what is the difference between setting benchmark and self calibration in DTX

answer: setting the benchmark is to use the permanent link and channel module of the equipment to restore the accuracy of the host and the remote at the same time, so as to ensure the maximum authenticity of the actual test results, for copper cable testing; The self calibration criterion is the self-test of the equipment's own system. You can choose to target the host or optical cable module. Once the self calibration fails, you can try to replace the permanent link adapter or channel module for recalibration. If it still fails, the equipment must be returned to the original factory for maintenance. (end)
