1.To achieve best performance of a Wireless LAN, the location of Access Point() must be carefully chosen.In most cases, finding a power supply for is a common obstacle.2.Power over Ethernet(PoE) technology provides the Perfect power solution to help overcome these obstacles.In Ethernet, four pairs of C5 or C5E twisted pairs are used as the medium for transmission.The actual data transmission, however,only takes up 4-pairs of wires (pairs 1-8). PoE technology utilizesthe remaining pairs(pairs 4-5 and 7-8 to conduct electricity).1.Product Name:POE Injector / Splitter2.Data PIN:1/2,3/63.Power PIN:4/5+ & 7/8-4.Data in:Connects PC/HUB/Switch5.Dimension:50mmx27mmx24mm6.Ethernet Cable Connector:RJ-457.Ethernet Data rate:10/100 8.Ethernet Cable:TIA/EIA 568 Cat.59.Operating Temperature:0 - 40 Degree10.Storage Temperature:-40 - 70 Degree11.Operating Humidity:10% to 80% RH12.Storage Humidity:5% to 90% RHNote this one is for 10M/100M,without adapter, with out earthnet and power connectiong cables.size:50mmx27mmx24mmMaterial:ABS plastic + metalcolour:BlackPackage Contents:4 * POE injector SplitterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
