Launch scroll The principle of transmitting a scroll is to consume the light in the "high level" mode through multiple large radians. The following figure shows how to use peripheral adjustment devices, such as the "launch scroll" to enable a common light source to emit "High Level" and "Low Level" modes) it can simulate the characteristics that VCSEL li

Fluke 2042 cable detector is a Portable handheld instrument used to track hidden lines in the walls, locate hidden points and short circuits in the cables, associate the electrical leads with circuit breakers, and track underground cables. Both residential and commercial applications, Fluke 2042 will save time and manpower for installation of new electrical facilities and Fault Diagnosis of existing devices

I need to perform the test correctly? A: The quantity of jumpers required depends on the reference method, the connector type of each line to be tested, and the connector type of the testing device. Let's take a look at the article "Optical Cable reference settings in English) in the fluke network knowledge base to answer your questions in detail. Question 3: Is there any optical cable that can be located in an external pipe by a testing instrument?

Currently, cabling system installers and network technicians are still using older Cable Fault Locating tools based on analog technology that was just 40 years ago. Even tools that use these simulation technologies often identify cables incorrectly or cannot discover signals in common work environments, they are the only choice. This is the case until today. R D engineers of fluke networks have applied decades of specialized cable testing technologie

you cannot log on to the network, the primary concern of technicians is whether the fault is related to the network or the user's PC. Next, determine whether the client and the network are correctly connected and working properly, and whether the client can access the network. Ensure that these features can solve many problems and lay the foundation for solving more complex problems. To solve network problems in a timely and efficient manner, first-line technicians are required to have a tool t

make it impossible or difficult to change it to ensure its authenticity. Fourth, there are many test parameters and the test results have high requirements on accuracy. Therefore, the test management software is required to easily search, query, and process multiple reports. These four aspects are also considered when fluke networks designs LinkWare software for cabling testing products. For the first part, that is, the requirements for the selection

judgment. Otherwise, it may waste a lot of time in the wrong direction. The statistical data shows that the switch port and network card work in full duplex and half duplex) mismatch accounts for a considerable part of the fault.To sum up, simply look at the green or yellow LED lights on the NIC or switch to make judgments on the cable, Nic or switch port. Otherwise, incorrect judgment due to a simple phenomenon will lead the fault diagnosis to go astray and waste a lot of time. In addition, th

include: whether the connection pulse of the NIC is available and normal (power level and polarity), and whether the NIC level is normal, whether the speed of the network adapter matches the speed of the hub or switch (10 M or 100 M), and whether the network adapter works in a way that matches the network device (full or half duplex ), whether the network card is very wrong frame (long horizontal frame and short frame) And what protocols are bound to the network card.

frame sizes to start the test. Elasticsearch allows you to report the actual uplink and downlink throughput in bytes per second, and also reports the number of frames that are sent and lost. It displays result data in tables or graphs and stores test results in XML format, so that you can file network performance documents during network deployment and trial run, or file the baseline performance.

◎ Comprehensive layer-7 testing The integrated protocol analyzer fundamentally solves the problem that has plagued network administrators for a long time. It can be tested from the physical layer to the application layer. That is, it starts from the cable test and ends with packet capture and decoding.◎ Integrate almost all network testing tools The network integrated protocol analyzer integrates the customer's Network Monitoring and Fault Diagnosis functions into a hand-held instrument. It can

Management Right in my hand, haproxy in my hand, I can be very flexible.About Haproxy and Nginx, I chose the former, there is no reason. Nginx can do, I have node. Of course, the team also used Apache, Baidu after the people came to ignore the reason for Nginx. Or, now this set is Baidu's people left behind. Think about the choice between IIS and Apache three months ago.I set up a node server, do my web front-end server, anyway this business is independent, I directly use a separate environment

Fluke Networks Fluke Network) recently released a new NetTool II series online network multimeter with the NetProve diagnostic function. It diagnoses Enterprise Network and application connectivity faults four times faster than traditional methods.The newly released NetTool II series has a simple one-step NetProve test function, allowing technicians to quickly and conveniently identify the root cause of the

By using the three important test tools in this toolbox-including a cable tester, an online performance tester, and a digital wire detector-technicians can

to be relatively small and negligible. The actual results show that the same is true for five types of systems. However, as the metrics of cat5e and cat6 systems are more stringent, the margin of test limit is very small. Therefore, the error caused by the test connection line cannot be easily ruled out. In actual tests, many originally qualified cable links will be regarded as unqualified. Because it cannot be determined whether the problem is caused by the test connection line or the link its

Added support for CDP and EDP in the latest NetTool and LinkRunner, which will greatly improve the network status information provided to users during fault diagnosis. CDP is the abbreviation of Cisco Discovery Protocol; EDP is the abbreviation of Extreme Discovery Protocol. This article describes the use of CDP and EDP protocols and the information available from LR and NT during network diagnostics. Technical Background: Many network management software use the "Automatic Di

standards. Commercial systems have higher requirements for cable installation and have a large number of standards for installation and testing. The authenticated network is the standard network. What does this sentence mean? Certification means to make a measurement and compare it with existing standards to determine whether it is qualified. For example, using a DSP series such as Fluke network or OMNI series instrument to measure the bandwidth of M

cable itself. Therefore, the insertion error introduced by the adapter must be ruled out. For example, Fluke networks provided an adapter to test the four Optical Fiber Links and recommended the best test method. The connection diagram of the two optical cables tested using the DSP4000 FTA4X0 optical fiber test adapter. The circle in the figure is the transfer method, and the impact of the transfer adapter is excluded from the final test results. In

training should include certification testing courses provided by BiCSi or ACP cable professional association, or training provided by tester manufacturers, such as CCTS training provided by fluke network.5. The accuracy requirements of the Test Instrument should meet the level III accuracy described in the TIA 6 standard. The test instruments include appropriate interface adapters that must meet the accuracy requirements. The accuracy requirements f
