Olson Technology OTLT-87XX-40-SA - Manual (Page 4)

INTRODUCTION
The Olson Technology OTLT-87XX-40-SA is a very cost effective indoor wideband laser transmitter
with an RF passband of 10 to 4,000MHztypical, 10-3,600MHz guaranteed. These transmitters are
intended for indoor applications. They combine the transmitter and universal AC power supply in
one compact housing that has a footprint of 7.5" x 5.5" x 1.6". The optical output power of each
transmitter is 10dBm. Each transmitter has a universal power supply and will operate from 90
AC
at 50 or 60 Hz to 240V and consumes about 10 Watts.
The OTLT-87XX-40-SA is an ideal for putting satellite signals on to fiber. Test points are provided
for laser output power and current to allow for historical review of operating parameters. Positive
cooling is provided by means of a small, high-MTBF fan, which may be replaced in the field
without interrupting the operation of the unit. The OTOT-87XX has flanges on the bottom to
allow mounting it to a flat surface. The available OTLL-RMKIT-1 will allow mounting up to
three of these units in a standard 19" rack.
INSTALLATION / ENVIRONMENTAL CONSIDERATIONS
The OTOT-87XX transmitter is specified to operate from -10°C to +55°C. They usually do not
require an air-conditioned environment. They should be mounted in an adequately ventilated
area. Like all electronic equipment, it will generally have a longer life span if it is not operated at
the upper limit of the temperature range. Installation in wet areas or areas of extremely high
humidity should be avoided. Extremely dirty or dusty areas should be avoided if possible.
Objects or debris should not be allowed to block the openings in the housing or the fan. The unit
should not be installed in areas that are accessible to children.
The OTOT-87XX may be installed and operated in any position on a flat surface. The unit has
four slots in the bottom plate to accommodate mounting hardware. 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.
