Features:1Multifunction: Compliant with IEEE802.3 10Base T and IEEE802.3u 100Base TX, 100Base FX standards with 10M 100M self adaptive capability Ethernet interface can be self adapted for direct connection crossover network cable connection support full half duplex mode supports IEEE802.3X duplex flow control and half duplex back pressure flow control supports broadcast windstorm prevention function. 2Strong Anti Interference Ability: Stable data transmission, one RJ45 port and one single fiber SC optical port, realize the optical signal conversion between Ethernet and fiber. Single mode SC fiber media converter set, up to 25KM. 3Single Mode Fiber Converter: Using optoelectronic modules, providing good optical and electrical characteristics, ensuring reliable data transmission and long service life. Compared with dual fiber data transmission, core fiber can complete signal transmission in a single channel, and the number of modes is doubled. 4Metal Housing: Made of metal housing, it is sturdy and durable and has a long service life, suitable for indoor and outdoor working environments. Strong heat dissipation: There are heat dissipation holes on both sides of the device to keep heat dissipation and can work for a long time. 5Easy Installation: Compact design, plug and play, just plug in a single SC fiber port and UTP port, and it works immediately, strong drop resistance, suitable for indoor and outdoor environments.Package included:1 x Converter A1 x Converter B
