10/100BASE-T Fast Ethernet
Media Converter
NMC-3305 User’s manual
Rev:2.1
1.Overview
T
he Media Converter complies with IEEE802.3,
IEEE802.3u, IEEE802.3x Standards. It is designed to
convert data signal between 100 Base-Tx and 100
Base-Fx fast Ethernet. The data signal converted by
such high performance media converter can be
transmitted up to 2Km maximum by fiber-optical cable.
The Converter is equipped with two fiber optic
connectors (One for transmitting-Tx and another for
receiving-Rx), two RJ-45 Jacks and one external
power supply receptacle. Six LED indicators are
built-in for easy diagnosing and monitoring the status
of power, Unshielded Twisted Paired (UTP) Link, UTP
Activity, Fiber Link, Fiber Activity, Full duplex and data
rates. It can be configured automatically for Full
Duplex or Half Duplex operation.
It is compact, cost-effective, low dissipative, high reliable
and stable. It can be used in standalone applications or
Rack-Mounted applications
where multiple media
converter can be inserted into a rack-mount chassis (Up
10 units) and allowing all the converters to be powered by
a single internal power supply.
