HEF3201G-2SFP is Ethernet fiber switches designed to transmit and receive 10/100/1000Mbps data over three ports. Available in industrial temperature grade, units feature half or full duplex mode and Auto-Negotiation to 10Mbps or 100 Mbps or 1000Mbps Ethernet rate without adjustments. The optical interfaces operate at a 1000Mbps rate. Plug-and-play design ensures ease of installation and no in-field electrical or optical adjustments are required. Features included are low power consumption, LED indicators for monitoring equipment link and performance operating status and auto resettable voltage transient fuses. With 12VDC input voltage on standalone or rackmount chassis, the HEF3201G-2SFP are outstanding products for transmission of three 10/100/1000Mbps Ethernet signals.
