对以太网(坡)是一种革命性的中欧ology that enables delivery of power over standard Ethernet infrastructure to facilitate quick and easy installation of WLAN access points, network cameras, IP telephones and other IP-based devices. The proliferation of Ethernet-connected devices such as Pan-Tilt-Zoom (PTZ) security cameras, 802.11ac and 802.11ax access points, LED luminaires and Internet of Things (IoT) appliances has created an unprecedented demand for more power. PoE is the key to efficiently, cost-effectively and reliably power network devices.

Microchip is an innovator and thought leader in PoE technology, as well as a major contributor to the IEEE®802.3af, 802.3at and 802.3bt standards.

We offer a comprehensive end-to-end portfolio of PoE solutions comprised of PoE ICs and PoE systems (midspans/injectors and switches). As both a system and chipset supplier, we provide foolproof PoE solutions to address your unique business requirements.
