PD-AS-601/12 12V Active Splitter
PowerDsine’s active splitters enable data terminals that were not originally designed to accept
power from the Ethernet, to be powered by standard Power over Ethernet switches and midspans.
Power over Ethernet (PoE) technology enables IP telephones, wireless LAN access points, security network cameras and other types of data terminals to receive power, along with data, over standard
Ethernet cables upon which data and power flow in parallel. Although a standard defining PoE already exists (IEEE 802.3af), many contemporary terminals are designed and deployed without the ability to accept power via their LAN input – a basic requirement of the standard. Such devices can only accept power through their DC jack while their RJ45 input accepts only data. Moreover, such devices might only accept voltage levels lower than the standard’s 48 volts dc. Using the active splitter, these terminals immediately become PoE–ready without any modification required on their side.
The splitter is being identified as a powered device (PD) in front of the switch (or midspan) and after being detected and powered, it physically splits the data and power streams, arriving over a single сable, into two separate cords (LAN & DC) which go directly to the data terminal. Voltage regulation is also performed to the level required by the terminal (18V or 12V or 5V).
