INTRODUCTION
The Olson Technology Inc. RPT-323x is a high quality, cost effective, Return Transmitter module designed around the latest
optical transmitter technology.
The RPT-323x is a series of replacement broadband return transmitters for the HLR3830 series of
optical nodes. The performance is equivalent to or better than that of the original transmitters. It can be used in the same
applications as the original transmitter. Please consult Olson Technology for our latest product list. ALL standard units have
SC/APC connectors.
Note: Olson Technology does not recommend or support the use of FP lasers for VOIP or analog video.
The RPT-323x receives preconditioned +24 VDC from the Node and plugs directly into the preexisting locations within the Node.
The primary RF connection is made through the coax cable which connects to the top of the unit. The transmitter can be ordered
with an optical connection that will match the factory setup. Heat transfer for the RPT-323x is provided via the bottom surface of
the module to the Node housing for full outdoor temperature operation.
INSTALLATION / ENVIRONMENTAL CONSIDERATIONS
The RPT-323x operates with an exterior temperature on the Node of -40 to + 70°C. However, like any other electronic device, it will
probably have a longer life span if it is not operated at the upper limit of it's temperature range continuously. Installation of the
RPT-323x should be done such that water, dirt and other contaminates do not enter either the Node or the module. Do not install
equipment in locations that are accessible by either children or other unqualified personnel. This unit is meant to be field-
installed into the HLR3830 Optical Node by qualified field service technicians.
The RPT-323x installs into the optics section of the node between the receiver and the power supply. The transmitter can be hot
swapped without damage to the module or node, but should be fully screwed into place before plugging in the power connector.
The retaining screws should be simultaneously worked down. Do not fully tighten one screw before partially engaging and
tightening the others. Remove the dust cover from the optical connector and the bulkhead adapter and plug the together. Note
which connector the fiber from the transmitter is plugged into. Care should be exercised to avoid breaking or kinking the fiber,
and that there is enough slack for the node to be opened and closed without pulling on the fiber.
CAUTION: The “standard” units all use angle physical contact optical connectors (APC) with green bodies or boots. Some
configurations may use flat/ultra physical contact connectors (UPC) with blue bodies or boots. You can not mate the two
different types and achieve satisfactory performance. Be sure to clean all fiber using proper fiber cleaner. A lint free cloth such as
a chem-wipe or similar wipe may be used.
Route the coaxial cable from the transmitter along the power cable and through the plastic clip on the interface board. Plug the
cable into the connector labeled “LSR” on the board. Be sure to close and tighten the cover of optics section before closing the
node.
