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.
