Design selection of high-speed broadband network high-speed broadband network transformer transformer design material requirements In order to optimize the digital subscriber line (DSL) technology, to ensure the high-speed Internet access network has a higher transmission rate in the signal transmission process, signal transmission loss and smaller distortion, it is essential to choose the core material, the performance will be able to further optimize the signal line transformer and separator. In the new Internet applications, such as television and telephone conference and Telecommunications dynamic web page download and software download, the central office (CO) to the user terminal (CPE) of the last mile need to transfer large bandwidth. In this case, the digital subscriber line (DSL) technology, and increase the speed of digital signal transmission in the traditional telephone twisted pair to the target. At present, is a commonly used three kinds of DSL technology, namely ADSL, SHDSL and VDSL. In these three kinds of access network technology, ferrite device is the key device for use. This kind of device can increase the transmission distance of the signal to improve the DC bias under the integrated services digital network bandwidth and the traditional telephone service (ISDN/POTS) separator (Splitter) performance. Select 1. network transformer ferrite materials and parts of the network transformer ferrite materials and parts of transformer The core is the most important material in the transformer, people usually liken it to the heart of the transformer heart, so we try to choose the type of design, such as EPX and EPO (Figure 1), not only improve the electrical performance of the d
