1. General
Our 10/100M fiber optical Media Converter is used in data communication between
100Base-TX twisted pair and 100Base-FX optical cable or 10Base-T twisted pair and
10Base-FL optical cable. This product is most applicable for use as connector for
intelligent community or Fiber to The Desk. It is automatically adaptable to transmission
rate up to 10 Mbps and 100 Mbps, and convenient for upgrade by users. The product
extends the ultimate network transmission distance from 100 m to more than 100 km,
making it easily to realize interconnection among mainboard servers, repeaters,
concentrators, and terminals.

4.3 Description of Working Status
Status of indicator lamps
■PWR indicator lamp ON indicates that power has been connected and
power is being supplied normally.
■ RJ-45 lamp: After the network cable is connected, the left green lamp is ON
if it is connected to a 100Base network, while fails to light up if it is connected
to a 10Base network. The right yellow lamp is a network indicator lamp, which
will flash if network works normally. If the network cable is not connected,
both indicator lamps will not light up.
■FDX lamp ON indicates correct connection of the twisted pair and flashing
of the lamp indicates that data transmission is ongoing.
