Power over Ethernet (PoE) is a networking technology that offers the ability to deliver both low voltage DC power and data over a standard Ethernet cable. This ability drives the consolidation of low voltage DC powered devices onto a single Internet Protocol (IP) network. A PoE system converts the line-voltage AC power to specific DC power, then transmitting the power to connected devices over structured cabling. An Ethernet twisted-pair Ethernet is designed to transport a differential signal, its anti-phase design (180° out of phase with each other) allows the transfer of data and power through a single Ethernet cable without interfering with each other. The proliferation of IP-connected network devices has been driving the need for high-bandwidth communication. While wireless networks provide flexibility, scalability, and ease of installation, they need to overcome the bandwidth and security challenges. With data transmission rates that can exceed 1 Gigabit per second, the PoE network provides guaranteed bandwidth for the secure data delivery.
