4-port industrial PoE switch, with 2 10/100/1000M Ethernet PoE ports and 2 gigabit SFP slots, for connecting with devices like computer, switch, hub, server, etc, as well as powering network camera, VoIP, wireless AP and other PoE supported devices. Optical fiber SC interface extends network transmission distance limit from 100m to above 25KM. It simply connects remote multiple motherboard servers, relays, hubs, terminals and multiple terminals. ONV-IPS31042PF product components were rigorous screened, have superior performance in stability, environmental adaptability. Shells were made by aluminum extrusion, more lighter, stronger, better resistance ability to corrosion and electromagnetic interference, ensure stability and security of Industrial Ethernet Switch, plus standard DIN-35 rail type installation method. Power input also chooses a suitable industry-standard types of power, to get more powerful suitability to environment.
