10BASE-T TO 10BASE-FL MEDIA CONVERTERS
2. Introduction
2.1 Description
Use the 10BASE-T to 10BASE-FL Media Converters to
connect conventional copper-based networks to fiber-
based networks. These converters support both an RJ-45
jack and a pair of ST or SC fiberoptic connectors. They
comply with the IEEE 802.3 10BASE-T and 10BASE-FL
standards, and are compatible with other 10BASE-T/
10BASE-FL and 10/100-Mbps Ethernet devices.
An MDI/MDI-X button allows the media converter to
connect directly to either a workstation, switch, or hub
using crossover or straight-through cable.
Using 820-nm multimode fiber, the LE1605A-ST
converter spans distances up to 1.2 miles (2 km). With
1310-nm single-mode fiber and the LE1606A-SC, the
distance between a LAN switch and another switch or a
file server can be up to 9.3 miles (15 km).
Figures 2-1 and 2-2 show the available models.

CHAPTER 3: Installation
3. Installation
3.1 MDI/MDI-X Connection
Before plugging in and installing your media converter,
you’ll need to set the MDI/MDI-X button. This button
selects whether you need to use crossover or straight-
through twisted-pair cabling to connect the RJ-45 ports
on the 10BASE-T portion of your network. (See Figure
3-1.) Simply set the button as described in Table 3-1.
Figure 3-1. MDI/MDI-X button.
NOTE
When the button is pressed in, MDI-X is selected. When the
button is out, MDI is selected.

3.2 Typical Applications
Once you’ve set the MDI/MDI-X button, you’ll need to
determine which application you’ll use.
In Examples 1 through 3 (see Figures 3-2 through 3-4),
two media converters are used to extend the distance via
fiberoptic cable between two 10BASE-T devices. In
Example 4 (see Figure 3-5), one media converter is used
to connect a 10BASE-T network to a 10BASE-FL device
via fiberoptic cable.

3.3 Installing the Converter
After you set the MDI/MDI-X button as described in
Section 3.1 and determine how you will use your
converter as shown in Section 3.2, you’ll need to place
the converter on a desktop or mount it on a wall. Next,
power on the converter. Connect the converter to a
10BASE-T device or network segment. Finally, connect
the converter to a 10BASE-FL device or to another
media converter via fiberoptic cable. Follow the steps
listed below:
1. For desktop installation, affix the four non-skid
rubber feet to the bottom of the converter.
For wallmount installation, use the underside of
the converter as a template to measure and mark
out the position of the holes onto the surface
where you will install the converter. Then use the
two mounting screws provided to mount the
converter firmly in place.
2. Connect the appropriate power supply for your
country to the power connector on the side of the
converter. Plug the power supply into a suitable
power outlet.
CHAPTER 3: Installation

16
10BASE-T TO 10BASE-FL MEDIA CONVERTERS
3. Power on the converter. The power LED should
light. If it does not, make sure that the power
cable is plugged in properly.
NOTE
When the converter is connected to a 10/100BASE-T
device, it will run at 10 Mbps, half-duplex mode.
4. Make sure that the Category 5 straight-through
twisted-pair cable between the 10BASE-T device
(hub or switch) and the converter is no longer
than 328 ft. (100 m).
5. Connect one end of the cable to the RJ-45 jack on
the converter.
6. Connect the other end of the cable to the RJ-45
jack on the 10BASE-T device.
7. Connect one end of a fiber cable to the ST or SC
connectors on the converter.
8. Connect the other end of the fiber cable to the ST
or SC connectors on the other converter or
10BASE-FL device.
Installation is complete.

17
4. LED Indicators
Once your 10BASE-T to 10BASE-FL Media Converter is
properly installed, it operates maintenance-free.
Several LEDs tell you the status of the converter and the
network at a glance. See Figure 4-1.
Figure 4-1. LED location.
• The Power LED (located on the side of the
converter) lights to indicate normal operation.
• (2) Link LEDs light when receiving link pulses
from a compliant device.
• (2) Receive LEDs flash or light when data packets
are being received.
