As demands for connection from networking devices such as IP phones, IP cameras and access points increase, deployment complexity and cost rise as well. For less cable usage and investment, Power over Ethernet (PoE) technology provides both data connection and electrical power to devices through just one cable without power-socket restriction. Featured with the benefits of PoE technology, Zyxel's PoE Injectors, PoE12-30W, all provide super-fast LAN connectivity with high-power budget; easily connect to PoE devices over Cat 5e or above cable. The PoE12-30W supports PoE+ and PoE++ standards respectively, both ensure interoperability with other standard-based PoE-capable devices.
