To extend the range of a PoE connection in harsh outdoor conditions: consider using the Intellinet Network Solutions Outdoor Gigabit High-Power PoE Extender Repeater (561211). This device is designed to extend PoE connections up to 100 meters (328 ft.) via Cat5e or Cat6 cables and can be cascaded with up to five extenders for a total distance of up to 500 meters (1640 ft.). It is IP65 rated for protection against dust and water: operates in temperatures ranging from -40-75°C (-40 - 167°F): and requires no additional power supply as it draws power from the PoE input. Installation is straightforward: connect the "PoE In" port to your PoE injector or switch and the "PoE Out" port to your PoE device (e.g.: VoIP phone: network camera) using existing Cat5 cabling. The extender supports IEEE 802.3at protocol: delivering Gigabit data speeds and up to 25 watts of power to connected devices. Cascading multiple extenders increases transmission distance: though additional power losses may occur with longer cable lengths. This solution minimizes wiring costs and ensures reliable power and data transmission over long distances in challenging outdoor environments.
