PoE - Power over Ethernet Applications & Solutions

TDK PoE - Power over Ethernet Applications and Solutions feature TDK's expanded line of ALT series SMD pulse transformers to be used in combination with ACM and MCZ series common-mode filters. These are used in various PoE applications that are compatible with 1G/2.5G/5G/10GBASE-T, 10/100/1000BASE-T, and PoE+ (600mA) standards. PoE is a technology that allows electrical power and data transmission to be carried simultaneously through a single cable versus through a separate power cord and network cable. PoE reduces the number of cables and wires necessary for installation and allows for design flexibility, as device placement no longer relies on the availability of an electrical outlet. PoE is capable of supporting higher transmission speeds while still providing outstanding reliability and meeting compact design targets. TDK PoE - Power over Ethernet Applications and Solutions allow for greater scalability as the number of connected devices and LAN interfaces on each device continues to grow and more electronic components are used in servers and routers, as well as in other network and communication devices.
