PD-Switch combines flexible copper and fiber interface options with port and packet-based traffic prioritization while extending network range by utilizing Power over Ethernet (PoE) technology. The (PoE) PD-Switch is a full-featured, 10/100Base-T MAC layer switch that extends the range of Ethernet networks, and increases port density, while being powered via IEEE 802.3afcompliant PoE through its "PD-port" (eliminating the need to run a separate power line for the device). Ethernet cabling usually runs only 100 meters; through the use of the PD-Switch, the outer range of an Ethernet network can be extended by an additional 100 meters.
