OPTONE 1000M Optical Fiber Transceiver achieves optoelectronic switching from 10/100/1000M 朤X to 1000BASE-FX so as to enlarge high-speed, high-bandwidth, and multi-model products of Ethernet data, which guarantees demands of different transmission modes. The maximum extension distance can reach 50KM Automatic switching between full duplex and half duplex Automatically adapt to twisted pair direct connection and crossed line modes Work under 10M, 100M, or 1000M, convenient for different transmission speedExcellent quality guarantee and particular aluminum structure design, with built-in heat emission fan Technical parameter Protocol IEEE802.3Z IEEE802.3ab Interface SC（1000Base-FX） 　 RJ45（10/100/1000Base-TX） Indicator 1000M: The indicator is on when the transmission speed is 1000M, and off when the rate is 10/100M FX: The light is on in case of fault, or it, s off POW: Power supply indicator TXD: Transmit data indicator RXD: Receive data indicator FDX/HDX: Full/half duplex indicator Power supply Built-in:94mm?0mm?6mm Environment Working temperature: -30℃~50℃ 　 Storage temperature: -40~70℃ 　 Humidity: 5%~90%(No condensation)
