AMP AMP module module supply information - AMP module offer five modules with two AMP six module. AMP over five cable conductor module is AWG26 (7 / 0.16mm) or AWG24 (7 / 0.20mm) of bare copper wire. Cable AMP ultra-five modules of this structure is relatively soft, bending resistance, ensuring that the module in the course very convenient. At the same time because it is stranded copper wire, live cable management easier. FLUKE selection module with single test, RL, NEXT performance headroom than TIA568B standard to the factory. AMP ultra-five modules due to cable and connecting hardware and belong to the same brand, but also easy to make the characteristic impedance of the entire passage consistent RL to obtain the desired value. 2, live on-site production module for cable production module, are generally horizontal cabling remaining fraction line. The level of cable conductor structure for solid core conductor, Cat5e using AWG24 (1 / 0.511mm), Cat6 using AWG23 (1 / 0.574mm) of bare copper single line. This structure is relatively stiff cables, poor flexibility, more difficult to spot cable management. In addition, as the first crystal field installation is the use of simple hand pressure crimping tool crimping pressure head sequin and crystal solid core conductor crimp connection reliability and operator actions are greater relationship, on-site production of module performance, FLUKE selection module with single test, RL, NEXT performance of individual differences large and reliable mechanical connection point than brand finished module significantly worse. 3, the market purchase module market as a result of a variety of channels to purchase modules for modules to understand not very professional users, there may even buy into the live production of modules. Even buy brand modules, there may be a "cottage" goods. The author has found that clients at a project site for the module cable is twisted aluminum structural testing 5 / 0.16mm, the module is identified as a well-known brand products. FLUKE selection module with single test, RL, NEXT performance headroom almost all less than -10.0dB, this is obviously part of fake and shoddy products, but also in the general market, the purchase is likely to encounter problems. Transfers: Computer Training Network Second, the analysis module materials to meet the module performance TIA / EIA568B.2 standards must be of high quality raw materials. Raw modules covered include module cable and crystal head into two parts: one, the module uses a cable conductor anaerobic round copper rod, electrical resistivity <0.017241; Insulation HDPE, good brands such as UCC3364 etc; general support module and on-site production module can meet the requirements in terms of materials, but the market is difficult to ensure the procurement module. Some low-quality materials on the market cost module is low, the performance can only ensure conduction. Mainly reflected in: Conductor: the module market may buy aluminum, may also be used is of poor quality copper conductor resistivity of such a large, poor scalability; Insulation: the good is generally possible to use HDPE insulation materials, poor may be used in regrind, the dielectric constant of such materials is large and unstable, the elongation is small. In addition to almost no electrical properties, such modules exist short life, poor reliability shortcomings. 2, crystal head RJ45 connector (RJ) sheet metal substrates mainly nickel and then gold-plated phosphor bronze, gold-plated thickness generally 30u ", 50u", six crystal head gold layer thickness is 50u "(1.27μm ), crystal head mating cycles require more than 750 times the performance did not decline; plastic housing for PC, comply with UL-94-V0, crystal head shrapnel mating cycles require more than 750 times without breaking the metal supporting the brand finished module crystal head. tablets, the gold layer and the plastic housing materials within the factory standard test done, you can ensure mechanical and electrical performance requirements. live production modules supporting crystal head if from the original product, the quality can be guaranteed, if the crystal first on the market to buy, the performance of mechanical, electrical, fire prevention materials it is difficult to guarantee.
