Introduction
Product Overview
The Gigabit Multi-mode to Single Mode Converter range is primarily
designed for network or data installations that require extended
fiber distances between 850nm & 1300nm fiber mediums. Used
individually or in conjunction with other converters, the fiber cable
distances can now be greatly increased.
These Converters have been designed to support SC fiber optic
connectors for Multi-mode and Single-mode configurations. It can
also be adapted to used ST, MT-RJ and WDM type connectors,
thereby widening its application across different types of networks.
This flexibility allows the converter to easily connect to a Gigabit
network using the existing connectors and fibers found in today’s
networking environments.
At full-duplex, these converters can create potential distances of
up to 30km with single mode to single mode fiber between two
respective nodes. This media converter is designed for simple 'plug-
n-go' installation into a Gigabit network environment.

Installation
To successfully install your converter, please refer to the following
procedures:
lFiber Connector Plugs
lConverter Configurations
Fiber Connector Plugs
This converter uses industry standard fiber connectors that are
factory fitted with protective rubber plugs. The plugs ensure that the
connectors are kept clean by protecting them from outside
environments.
The optimum transfer of data is achieved through the use of clean
and dust free connectors - insert the protective plugs at times when
the converter is not in use.

Converter Configurations
The following diagrams are possible configurations that will expand
the physical distance of a Gigabit. They are especially suitable for
campus or premise backbones applications.

LED Indicators
This converter has several LEDs to enable you to determine the
status of the converter and the connection across your network.
They are as follows:
PWR Power – Green– illuminates to indicates
normal operation
LNK Link– Green– illuminates when receiving
link pulses from compliant
devices

Appendix B
Converter Mounting
This converter can be placed in any location that will make its
installation convenient. If you place the converter on a horizontal
surface or on top of existing networking equipment, please affix the
four rubber pads included in the package.
This converter can also be mounted on a vertical surface. Simply
use the underside of the unit as a template to measure and mark
out the position of the holes on to the surface where the unit is to
be installed. Then use two screws to mount the converter firmly in
place.
Please exercise caution when using power tools. Also, install this
unit away from damp or wet locations, or in close proximity to very
hot surfaces. These types of environments can have a detrimental
effect on the converter and cables. An ideal location is a lightly
cooled place such as a typical equipment room.

Appendix C
Cables
The following are some recommendations as to what you should
and should not do when installing cables. Remember - cables are
the deciding factor in network performance.
24mm
6mm
Try to
maintain
a bend
radius of
(min.) 4x
the diameter
of the cable
for UTP and
100x for fiber.
Try not to
allow the
cable to
twist too
much -this
creates a
strain on
the internal
cables.
Place cable ties
at regular
intervals -do
not over tighten
cable ties -try
to avoid using
with fiber.
Do not stretch
the cable
especially on
corners, in
vertical cable
trays and when
spanning long
distances.

About RJ-45 Cables
When connecting your network devices, use standard Category 3
eight-way cables for 10Base-T configurations and Category 5 cable
for 100Base-TX and 1000Base-TX. The pin assignments are as
follows:
