Connect the fiber-optic transceiver on the
media converter with the Single-mode SC
fiber connectors.
5.23 Connect to switch power adaptor
5.24 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, please refer to the device’s
Technical Manual.
5. Installing the Converter
5.1 For as a standalone unit:
5.1.1 Verify if the AC-DC adapter conforms to
your country AC power requirement
then insert the power plug
5.1.2 Check the type of UTP (see fig.3)
UTP complies with IEEE802.3
Standards, and has two types: T568A
T568B.

1. Overview
The Media Converter complies with
IEEE802.3, IEEE802.3u, IEEE802.3x
Standards. It is designed to convert data
signal between 10/100 Base-TX and
100Base-FX fast Ethernet. It supports
10/100Base-TX and 100Base-FX
applications. The data signal converted by
such high performance media converter can
be transmitted up to 120Km maximum by
fiber-optical cable.
The Converter is equipped with two fiber optic
connectors (One for transmitting-TX and
another for receiving-RX) and 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.
