Novel technology for the green laser pointer

On the green laser pointer body there could be added LOGO technics such as laser. In addition, shielded twisted pair normally has a layer of aluminum foil, in the manufacture, duplication of part of the aluminum layer is about 30%, after the aluminum foil into the cover since, so as not to leave any gaps, if shielded twisted pair of tight dwelling structure, then no matter how twisted bent, aluminum foil layer can not repeat part of the split of the phenomenon. 2.4.2. grounding in the construction of the insulation is also important: the building in any way grounded metal objects should be wrapped with a suitable dressing up dressing component elements (such as materials with metal bar, dressing of, etc.) should have as large high-frequency leakage current conduction area. not suitable for thin 3 shielded cabling project testing and quality checks on existing technology, the shielded cabling system can not shield the quality of the construction site quantitative test equipment test given the quality of the project refers to the quality shielded cabling only with the naked eye for qualitative inspection checks.On the green laser pointer body there could be added LOGO technics such as silk-screen. 3.1. shielding field test whether the link or channel link test test, field test instruments are used, so shielding system test is very simple: the standard shielded twisted pair should be adjusted, press the test button automatically, soon to be completed, including all the tests include shield (shield should be noted for the S line is: in the test instrument in shielded cabling system only contains the shield test connectivity. international standards in the rest of the system has not been shielded system performance test indicators, shielded cabling system quality assurance required by the Contractors in all aspects of the construction process to ensure that in the TIA / EIA 568B1.2-2003, the provisions shielding the link in the DC resistance of the shield must not be greater than 21Ω, then the test should be used to power equipment (such as: multimeters, etc.) for testing. On the green laser pointer body there could be added LOGO technics such as bat printing.3.2 quality inspection shield on the site, you can check the shield qualitative project quality, for example: F watch is shielded twisted pair with shield shield shield module shell was a 360-degree connection, there is no gap to the invasion of electromagnetic waves; F foil shield The ground wire should be twisted pair, after bending, in the twisted pair and shielded module banding, banding and shielding module close contact with the metal (You can also use the ground wire wrapped around the metal banding, but this will affect the progress of the project ); If the test when the shield and core wire short circuit fault, usually shield the wire, aluminum foil, or contact with the ground wire and wire cut through the sheath may be injured when bending wire, causing a short circuit;On the green laser pointer body there could be added LOGO technics such as silk screen rotary cutting. if the shield twisted-pair links of the RL values are poor, while the crosstalk value is not bad, there may be shielded twisted pair itself is defective. of course, water and other phenomena can be twisted; observed shielding shell is covered tightly. 4 . Conclusion With the popularity of intelligent building projects, many construction workers on the BA system, cable TV systems, TV surveillance systems, access control system has been used in the drain wire termination, so they are shielded cabling works have reached a very high level , so in recent years, has been less difficult to see that shielded cabling project construction article.
