These Signamax Media Converters provide a flexible and intelligent solution for long distance connections. The built-in 10/100/1000 switch enables the fiber cable connection to operate at 1000 Mbps, while remaining completely 1000BaseSX/LX or 100BaseFX/BX standard-compliant for the fiber optic connection for model number SX-065-1196SFPDR. For model number SX-065-1196ALX, this allows it to operate at 1000 Mbps connected to either a 10BaseT, 100BaseTX, or a 1000BaseT network, while remaining completely 1000BaseSX or 1000BaseLX standard-compliant for the fiber optic connection. The fiber connection can also operate in full duplex mode whether the RJ-45 port is connected to a full duplex switch or a half duplex legacy hub.
