SAFETY WARNINGS

LASER RADIATION

A laser transmitter emits invisible radiation that can cause permanent eye
damage. . Operate the transmitter only
with theproper opticalfiber installedin thetransmitter opticalconnector. Power to
the OTOT-300C should be turned-off or preferably, disconnected whenever the
optical connectorcover isopened and there is no installed fiber (as whenthe fiber
connector is beinginstalled orremoved from thetransmitterconnector).

The OTOT-300Cis designed forindoor use only.Directexposure to moisturemust
be avoided. Connect the AC Adapter into the OTOT-300C before plugging the
adapter into thewall.

AVOID DIRECT EXPOSURE TO BEAM

NEVER

USE ANY OPTICAL INSTRUMENT TO VIEW THE OUTPUT OF THE
LASER TRANSMITTER. “OPTICAL INSTRUMENT” INCLUDES MAGNIFYING
GLASSES, ETC.

NEVER

LOOK INTO THE OUTPUT OF THE LASER TRANSMITTER

NEVER

LOOK INTO THE OUTPUT OF A FIBER CONNECTED TO A LASER

TRANSMITTER.

NEVER

LOOK INTO OR USE ANY OPTICAL INSTRUMENT TO VIEW THE
DISTANT END OF AFIBER THAT MAY BE CONNECTED DIRECTLY OR VIA AN
OPTICAL SPLITTER, TO A TRANSMITTER THAT MAY BE OPERATING. THIS
SPECIFICALLY APPLIES TO FIBERS THAT ARE TO BE CONNECTED TO
RECEIVERS OR OTHER DEVICES AT ANY DISTANCE FROM THE LASER
TRANSMITTER.

SHOCK HAZARD

INTRODUCTION

The Olson Technology, Inc. Model OTOT-300C is a General Purpose CATV
Return Path Transmitter. It offers wide analog RF bandwidth of 5-300MHz. It is
available with a variety of laser options including 1310nm DFB, 1550nm DFB and
CWDM wavelengths at optical output powers ranging from1mW (0dBm) to 3mW
(+5dBm).

The OTOT-300C offers a low-cost alternative to digital return path
hardware. It is compatible with most analog RF return path optical receivers.The
Olson Technology, Inc. OTOR-300TripleReturn Path Receiver is anideal mate to
the OTOT-300C.

The OTOT-300C is built in a rugged castAluminum housingand

is powered from+12 Voltsto +16VoltsDC. (Power supply orderedseparately.)

The OTOT-300C features an RF Drive test point that will yield +10dBmV per
channel with a standard 5-42MHz CATV returnload. Theunit alsohas a 20dB RF
gain adjustment, which allows the unit to deal with non-standard CATV return
loads. The unit has a green LED to provide a positive indication that the unit is
powered and aDC testpoint that indicatesthe optical output power (1Volt/mW).

INSTALLATION/ ENVIRONMENTALCONSIDERATIONS

The OTOT-300C is specified to operate from -10°C to +55°C. It usually will not
require an air-conditioned environment. It should be mounted in an adequately
ventilated area.Like any other electronic equipment, it willprobably have a longer
life spanif it isnot operated atthe upper limitof the temperature range. Installation
in wetareas or areas of extremely high humidity should be avoided. Dirty or dusty
areas should be avoided if possible. The OTOT-300C should not be installed in
areas that areaccessible tochildren.

The OTOT-300C may be installed and operated in any position on a flat surface.
The unit has two slots in the bottom flange to accommodate mounting hardware.
The unit should be mounted by sliding under one screw and then installing and
tightening the other screw. If mounting requires a wood screw, use #6 or #8
(maximum) pan-head sheet metal screws. These are commonly available at
hardware stores. If mounting with a machine screw (to tapped holes), use 6-32
pan-head screws.
