So far, face dirt is the main cause of fiber failure. According to a survey commissioned by Fluke Networks by installer and dedicated network owner, dirty face is the top cause of fiber failure. It is estimated that 85% of Optical Fiber faults are caused by contamination of the optical fiber end face. Therefore, the end face must be checked and cleaned whenever necessary. It is equally important to check and clean the two ends of any connection, as po

process of the basic link includes the error of the test access line. The six types of standards are very strict, and the remaining margin is very small. Therefore, the error of the Test Line cannot be ignored. Most of the adapters currently available on the market are basic link adapters, for example, Fluke network's DSP-4000/4100/4300 Series Digital cable tester random mostly equipped with basic link adapters. During the test, the error may be high

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 the testing time of the "6" line to 12 seconds,

The Online Network Monitoring Interface Box of fluke network can maximize the perspective of the Full Duplex switching LAN and WAN network, and minimize the link failure time. Provides single-port or multi-port configurations. The Online Network Monitoring Interface Box can access all network traffic, including physical errors, in both directions of the full-duplex link. They are fault tolerant and support dynamic insertion of Network Monitoring and A

BKJIA editing Note: for the performance evaluation of vswitches under normal circumstances, note the following: features, application-level QoS Assurance, VLAN support, network management, and link aggregation, supports VRRP. In addition to the first two aspects, we have used the Spirent Test Center's fault generation/analyzer with 24 10 GB Ethernet filtering CV modules and 10 gbase

Vital: This is the highest standard of Web page quality. Vital's web page is usually a formal website for a company or a person. For example, search "fluke", Www.111cn.net is vital Web page. Useful: This is the second highest standard of web pages. Useful's web page refers to a Web page that answers query questions correctly. In my opinion, this is why Wikipedia is always in the front line in many searches. Relevant: This is the median score. Releva

Testing tools are the means to realize automatic testing, and reasonable use of test tools can not only improve the ability of network diagnosis, but also bring convenience to network management. Generally speaking, network testing tools in a broad sense can be divided into physical cable tester, network running Simulation tool, Protocol analyzer, special network test equipment, consistency test tool of network protocol and Network application analysis and Testing tool. The following selection o

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 practical. For the same reason, there are also

setting, only the CPU usage is seen as 50%. Always uncomfortable. Think about how good it would be if it could support 8 of them. It's 8 times times the size of a single core. A moment of tinkering, or not. It seems that you can only open up to the same number of CPU cores as the worker. That doesn't matter, 4 times times 4 times times. Better than nothing The second problem is the variable that calls the other function inside the for loop. For the sake of convenience, I used a single global. B

force is the entire cable, otherwise the force is the cable and the connection of the metal part of the connector.In the cable wiring construction, the cable tension is bound. Generally 9 kg or so. Please confirm its pull with the cable supplier. Too much tension will damage the symmetry of the cable.Cabling System Testing ProcessCabling System testing is generally divided into three steps.Wiring construction personnel with the test, at this time only testing the cable, cable line method, lengt

can use a similar solution that combines light sources with materials. Use multiple channels to process other operations. The global force, such as gravity, always affects the particle by a fixed acceleration in a certain direction. The local force affects the particles according to the previous position read from the position texture. Assuming that the particle is affected by a magnet, this is equivalent to making the particle affected by a local acceleration pointing to a certain point. The f

size (The relationship between any two views can be determined.) 1. autoLayout usage: Directly create constraints [self.view addConstraint: [NSLayoutConstraint constraintWithItem:blueView attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual toItem:redView attribute:NSLayoutAttributeLeft multiplier:1 constant:0]];In this way, although the amount of code is large, it is absolutely feasible and one of the most fundamental ways to

following format: 　　item1.attribute1 = multiplier × item2.attribute2 + constant In this equation, attribute1 and attribute2 are variables that address these constraints when the automatic layout can be adjusted. When you create a constraint to define other values. For example, if you define the relative positions of the two buttons, the start position of the second button is 8 pixels after the end position of the first button. The linear equation is as follows: 　　button2.leading = 1.0 × button

AutoLayout frequently used layouts (including StackView)Foreword: Personal comparison likes in Xib and SB go up with AutoLayout, also many people will go to use the VFL, and masonry to do the adaptation, of course also some novice use the proportion of screen size to do.Of course, in contrast, individuals prefer to use AutoLayout to pull constraints on the interface. Sense of efficiency is higher, but the team development words may be added to the con
