INTRODUCTION
The Olson Technology Inc. 6920-RT-x is a high quality, cost effective, Return Transmitter module designed around the latest
optical transmitter technology.
The 6920-RT-x is a series of replacement broadband return transmitters for the 6920 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. The basic standard models are listed below. There are many other custom versions and
single to dual upgrades available. 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 6920-RT-x 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 RF connector on the bottom of the transmitter. The transmitter can be ordered
with an optical connection that will match the factory setup. Heat transfer for the 6920-RT-x is provided via the bottom surface of
the module to the Node housing for full outdoor temperature operation.
INSTALLATION / ENVIRONMENTAL CONSIDERATIONS
The 6920-RT-x 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
6920-RT-x 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 SA6920 Optical Node by qualified field service technicians.
The 6920-RT-x installs in the lid of the node. The transmitter can be hot swapped without damage to the module or node. The
retaining screws should be simultaneously worked down. Do not fully tighten one screw before partially engaging and tighten-
ing the other one.
Excess fiber should be coiled around the fiber organizer. Care should be exercised to avoid breaking or kinking the fiber.
CAUTION: The “standard” units all use angle polished optical connectors (APC) with green bodies or boots. Some configura-
tions may use flat/ultra polished connectors (UPC) with blue bodies or boots. You can not mate the two different types and
achieve satisfactory performance. There is a second bushing already installed to allow for simple upgrade to dual transmitters in
a single housing.
