DM9302EP Product Brief 10/100Mbps Ethernet Fiber/Twisted Pair Single Chip Media Converter with Local bus March 2009 Rev.1.0 The DM9302 is a fully integrated and cost-effective 10/100Mbps Ethernet Fiber/Twisted Pair Single Chip Media Converter with Local bus This new product provides basic Layer-2 switch functions and advance IEEE 802.1Q VLAN, priority queuing scheme. The DM9302 Fiber converter is complied with IEEE802.3 standards, and designed to convert data signal between 10/100 Base-TX and 100 Base-FX fast Ethernet. Media converters are connected between Fiber cable and twisted cable segments with network and also the simplest way to interconnect any equipment’s 100BASE-TX / 10BASE-T to the 100BASE-FX interface network.
