Edimaxs full series of media converter is designed to meet the needs for massive optical fiber network, & to provide the whole Ethernet/ Fast Ethernet network implementation. ET-912+ series converts the signals between two different transmission medium, allowing user a simple & cost-effective method to migrate between UTP cable & fiber optic cable. It can transmit signals up to 2km (multimode) in fiber medium, allowing users to extend network. ET-912+ series is compliant with IEEE 802.3 10 Base-T & IEEE 802.3u 100 Base-TX/100 Base-FX standards. The device comes with one RJ-45 port to connect to a 100 Base-TX device such as workstation or switch & one fiber connection to connect a 100 Base-FX device. User could monitor the device through feature LED. In addition, fiber link alarm could allow user to monitor & maintain their critical fiber link more effectively. Built in voltage supervisor IC will automatically reset all chipsets in converter as power voltage drop below 2.9V, this action can make sure fiber port & TP port work normally when thunder storm or power unstable occurring causes the power electricity suddenly down in an instant time.
