PoE Power-on-demand products

Power-on-demand midspans allow your best-in-class network switch to handle the data without limiting your available power. This advanced midspan technology provides full-power on every port and is a more cost-effective solution to expand your network capability because it isolates the data to the switch and the power to the midspan.

Phihong is committed to providing the complete information you need to install and operate our best-in-class midspans. We thank you for your interest in our PoE power products.
