Gigabit PoE Injector

48 volts power over ethernet copper injector gigabit

The DCE 48V-POEI-GB is an IEEE 802.3af Power over Ethernet Injector which provides DC 48V over Ethernet cables. The DCE 48V-POEI-GB IEEE 802.3af Power over Ethernet Injector inserts DC Voltage into Cat.5 cable, allowing the cable between the Injector (DCE 48V-POEI-GB) and Splitter to transfer data and power simultaneously. The maximum distance between the Injector (DCE 48V-POEI-GB) and Splitter is 100 meters. The DCE 48V-POEI-GB combines the Ethernet digital data with Power over the twisted pair cables as an IEEE 802.3af Power over Ethernet Injector. The IEEE 802.3af Power over Ethernet splitter separates the digital data and power into two outputs.

Unlike existing Power over Ethernet Injectors, the DCE 48V-POEI-GB also provides 1000Mbps Gigabit Ethernet connection ability, as well as the 10/100Mbps fast Ethernet connection ability.

With IEEE 802.3af Power over Ethernet devices installed, the system administrator only has to use a single RJ45 Ethernet cable to carry both power and data to each device. Additional benefits include cost savings, ease of networking planning and high network reliability. The DCE 48V-POEI-GB makes network connection while migrating or splitting the power and Ethernet digital packets. This allows the DCE 48V-POE-GB to connect to any IEEE 802.3af compliant device, AP or IP phone.
