1.Overview
The 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.

UTP complies With IEEE802.3 Standards, and has two
types:T568A T568B.
Fig.1 The type of UTP
NOTE: G: Green; O: Orange; B: Blue; P: Palm
Parallel cable: connect T568A to T568A,or T568B to
T568B
LED Color Function
L/A-FX Green Lit when fiber connection is good
Blink when fiber data is active
SPD-FX Green Blink when fiber data is active
L/A-TP Green Lit when TP connection is good,
Blink when TP data is active
SPD-TP Green Lit,100Mbps; Non-light 10Mbps
FDX Green Lit when full-duplex mode is
active
PWR Green Lit when +5V power is coming up

Crossing-over: connect T568A to T568B
3.1.3 TP Port List (Fig.2)
4.0 Installing
4.1 TP port installing
The RJ-45 port can connect the parallel lines “=” or The
cross lines “X”
4.12 Fiber port installing
Connect the fiber-optic transceiver on the media
converter with the Single-mode SC fiber connectors.
4.13 Connect to switch power adaptor
4.14 Check the appearance that converter instructions
light. If connection right, the PWR,L/A LED is bright;
Otherwise checking the Fiber port and TP port.
Note: Connecting to Router, Bridge or Switch.Pleasa
