Trendnet TPE-103I PoE adapter

Power over Ethernet (PoE) Injector The Power over Ethernet Injector, model TPE-103I, combines electrical power with a Fast Ethernet network connection to produce a Power over Ethernet (PoE) signal.
Connect this device to a non-PoE switch and then run an Ethernet cable for up to 100 meters (328 Ft.) to network PoE devices.
No need to buy a PoE switch—use an existing open port from a non-PoE switch to save installation and equipment costs when installing TRENDnet PoE access points and IP cameras in remote locations. This compact device safeguards valuable network equipment with short circuit protection. Quickly create an integrated PoE and non-PoE network.
