DM9302
10/100Mbps Ethernet Fiber/Twisted Pair Media Converter with Local bus
1. GENERAL DESCRIPTION
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.
