摘　　要：PoE是一种通过标准通信电缆传输有限的低压直流电源的技术,PoE交换机发展了十几年,技术上已相对比较成熟,在PoE交换机实际开发设计及工程应用中给予更多关注的往往是交换机整机电源供电功率、供电端口数量、低功耗、通信速率等等,对在PoE供电链路中起到关键作用的网络变压器元件似乎较少提及。本文将主要阐述网络变压器在PoE供电链路中的作用原理及PoE技术对网络变压器的影响,以供相关设计开发人员参考。PoE is a technology that transmits limited low-voltage DC power through standard communication cables.PoE switches have been developed for over a decade and are relatively mature in technology.In the actual development&design,and engineering applications of PoE switches,more attention is often paid to the power supply power of the entire switch,the number of power supply ports,low power consumption,communication speed,and so on.There seems to be less mention of LAN transformer components that play a crucial role in the PoE power supply chain.This article will mainly explain the working principle of LAN transformer in PoE power supply links and the impact of PoE technology on LAN transformer,for reference by relevant design&development personnel.
