The TRENDnet Gigabit 4PPoE Injector, model TPE-119GI, is an 802.3bt PoE injector that combines electrical power with a Gigabit network connection to produce a powerful 95W 4PPoE network signal. The auto-sensing technology conveniently delivers the correct wattage needed to power your PoE, PoE+, and 4PPoE devices. Connect the Gigabit 4PPoE Injector to a non-PoE switch and then run an Ethernet cable with data and power to network a PoE device up to 100 meters away. It converts a non-PoE port into a 4PPoE Gigabit port and provides PoE (15.4W), PoE+ (30W), or 4PPoE (95W). The built-in power supply allows for networking a PoE device over distances of up to 100 meters, saving installation and equipment costs. The injector is IEEE 802.3af/at/bt compliant.
