INTRODUCTION
The Olson Technology Inc. 7-OR-RT is a high quality, cost effective, Return Transmitter module designed around the
latest optical transmitter technology. It is designed to operate and meet full specifications with an optical output level of
1 to 3 mW. The 7-OR-RT module is shown in Figure 1.
INSTALLATION/ENVIRONMENTAL CONSIDERATIONS
The 7-OR-RT operates with an exterior temperature on the Node of -40 to + 60°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 7-OR-RT 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 DiamondPoint 7-OR Optical Node by qualified field service technicians.
To plug the return transmitter module into the optical receiver’s main circuit board, follow these steps:
1. With a TORX TX09 driver, loosen the seven screws holding the optical cover in place. Notice that besides
protecting the optical receiver’s main circuit board, the optical cover also has markings that indicate where you will
install the 7-OR-RT return transmitter. See Figure 5 for a detailed view.
2. Flip the optical cover up and over, so that it lays bottom-side up in the cover of the 9-ORH optical housing.
3. Plug the 7-OR-RT into the 7-OR optical receiver. The pins on the underside of the 7-OR-RT fit directly into the
holes in the 7-OR module’s main circuit board. The return transmitter’s circuit board rests on top of the 7-OR
receiver’s factory-installed optical pigtail.
NOTE: Be sure the fiber termination of the incoming fiber matches that of the transmitter, an easy way to tell is by the
color of the termination. The transmitter will have either a green SA/APC, or a blue SC/UPC connector. The incoming
fiber connector MUST match this color. If the connector is green, but the fiber termination is blue (or vice versa), then
the signal passing through the fiber will be degraded and in many cases unusable.
