DBE-1200S
Chapter 1: Overview of the DBE-1200S
The Technetix DBE-1200S strand mount amplifiers and optical nodes are an innovative ‘crossover’ design which provides a
field upgradeable solution to deep fiber/fiber to the last amplifier (FttLA). Its RF function can be configured for use as a 1x1 up
to 3x3 or as an RF/optical hybrid as a single, dual, or triple output device. The amplifier provides reverse path transmission with
a hybrid amplification stage.
Forward and return path attenuation can be adjusted with electronic attenuators through software control. Electronic equalizers
can be adjusted via software for forward and return path equalization. Cable simulation can be implemented by inserting an
appropriate JXP module (available in 1 to 7 and 9 to 15 dB tilt values for applications up to 1.2 GHz).
The DBE-1200S has a highly ecient long-life switched-mode 90 W power supply (DBPSU-07-1) to provide power, with ample
margin, to the internal electronics.
Surge arrestors at the input and output ports protect the RF circuits in the event of lightning or mains power surges.
In the DBE-1200S these protection devices are field replaceable plug-in modules.
Benefits
■Full digital control and setup with user selectable integrated Automatic Temperature Control (ATC), Automatic Gain Control
(AGC) or Automatic Level and Slope Control (ALSC)
■Improved intermodulation distortion performance - innovative GaN technology operates to 1218 MHz
■Energy ecient hybrid technology provides more gain with the same power consumption
■Flexible and modular to meet changing network needs
■Technetix CPD Safe®technology and surge protection mean fewer reported faults, improved customer service
and a reduction in truck rolls
* Note: Common Path Distortion (CPD)
■On-board ingress detection facility provides an option to apply -6 dB or -40 dB of return path attenuation either by; (1)
local control through a USB connection in conjunction with the software, or (2) via a simple Frequency Shift Keying (FSK)
communications protocol via an FSK transmitter in the headend, or (3) through Simplified Network Management Protocol (SNMP)
control when the amplifier/node is outfitted with a Data Over Cable Service Interface Specification (DOCSIS) transponder.

DBE-1200S electrical/optical hybrid
In a hybrid configuration all of the upstream and downstream connections to the headend are through fiber. Here is an
example hybrid configuration of the DBE-1200S with one upstream optical transmitter module with two lasers, and a second
upstream optical transmitter module with one laser, and one downstream optical receiver feeding two downstream bridger
amplifier modules. Other configurations are also possible. All upstream data inputs can be combined on one laser transmitter.

Chapter 3: Installing the DBE-1200S amplifiers
3.1 Mounting the DBE-1200S housing
There are two options for mounting the DBE-1200S amplifier:
Strand mount
Two messenger clamps are located on the top of the housing and are secured with 5/16" x 18 threads per inch stainless steel
bolts. These should be torqued to 0.37 ft*lb (0.5 N*m).
Rear mounting direct to cabinet back panel
For mounting directly onto a cabinet back panel, the rear 5/16"-18 UNC bolt holes can be used with four 5/16"-18 UNC
threaded bolts (see following picture). When using this method of mounting, make sure that the bolt’s threads will not protrude
any more than 5/16" (8 mm) in length through the back board that the amplifier will be mounted onto. The total bolt length
should be 5/16" (8 mm) + back board thickness + washer thickness.
Mounting holes on the centerline of the back of the DBE-1200S housing are spaced 12-1/16" on-center.
They are 5/16"-18 UNC x 11/32" (9 mm) deep.

DBE-1200S
3.2 Electrical connections
1. There is a ground contact on the left side of the housing to connect a ground wire. A crosshead (Phillips)
screwdriver should be used to tighten the ground screw to a torque value of 0.37 ft*lb (0.5 N*m).
Grounding screw located
on the side of the housing.
2. To install the coaxial cable, cut the connector pins to a length of 1.1" (28 mm) for threaded connectors
as shown below. When using 5/8"-18 UNC threaded connectors and 5/8" reducing rings, add 7/64" (2.5 mm)
to the connector pin length = 1.2" (30.5 mm).
3. Tighten the connectors into the housing in accordance with the connector manufacturer’s specification. The maximum
torque force for the coaxial connector and 5/8" adapter ring is 14.75 ft*lb (20 N*m).

3.3 Closing the amplifier
The housings have a woven wire RF gasket and a rubber gasket to provide a seal between the housing base and lid.
The RF gasket provides shielding to prevent RF ingress/egress and the rubber gasket keeps out water. The rubber
gasket should be replaced if it is damaged.
To close the amplifier lid, first tighten the six lid securing bolts hand tight. Next, using a 1/2" wrench, or a cross head (Phillips)
screwdriver, hand tighten the lid bolts in the sequence shown in the figure:
1- bottom left bolt at hinge
2- top right bolt
3- bottom right bolt at hinge
4- top left bolt
5- left side bolt
6- right side bolt
Then, using a torque wrench set to a torque value of 3.7 ft*lb (5 N*m), go around again in sequence and tighten
to the final torque setting.
Following this sequence will ensure:
1. The rubber gasket between the lid and the amplifier housing is sealed correctly, providing a sound, watertight seal to
prevent water ingress.
2. A good RF seal between the RF gasket in the lid and the amplifier housing to prevent RF ingress/egress.
3. A good lid to housing contact for the dissipation of amplifier heat. The lid acts as a radiator when it is correctly
secured, keeping the amplifier operating temperature within operating limits when installed as recommended.

3.4 Configuring the Power Supply Unit (PSU)
The DBE-1200S has the following power supply options:
1. Local powering is achieved on the RF input port using a power inserter.
2. Remote powering through the External Power port (see item 16 on page six). Maximum AC power passing = 10 Amps.
See page Chapter 4.1 for removal/installation of PSU unit.
Fuses
Referring to the network design documentation, remove any fuses not required for passing power.
Remove fuses on the output ports of the
DBE-1200S if it is not necessary to carry power. Ext. power port

3.5 Powering up the amplifier
1. After any bench pre-configuration required by the network design and once the amplifier is mounted into the network
location, temporarily remove the fuses. Connect the RF cables to the relevant RF ports and connect the earth/grounding
wire (in accordance with local electrical installation regulations) on the right-hand side of the housing.
2. Using a true RMS digital voltmeter, confirm AC power is present on the port where incoming power is present in
accordance with the network design drawings. The voltage should be within the amplifier specification and thenetwork
design drawing calculation.
3. Install the input port fuse per the network design drawings and ensure that it is fully inserted into the fuse holder
for incoming AC power. Then check that the amplifier DBDCM module LED (DBDCM-A-x = red, DBDCM-B-x = green)
is illuminated.
The LED on the control module indicates
that the DBE-1200S amplifier is powered
up when it is illuminated.

Note: For advanced settings and configurations, please refer to the latest release of our BLL, BLA, or T-Box
Using a laptop with the Technetix BLL software installed or an Android device with the Technetix BLA software installed,
connect the laptop or Android device to the amplifier through the USB connection.
Next, carry out the following steps:
Note: Steps 1 to 3 can be completed on the bench if the amplifier is powered up before it is deployed.
1. The BLx should connect with the amplifier control module automatically when the software is running and the computer
is connected to the control module via the USB cable. To connect manually: with the BLx software running, click on Scan
Bus at the top left of the application screen.
This enables the BLx application to connect to the DBDCM control module. Once the communication with the amplifier
is established, the amplifier type name will appear at the top left of the application. All amplifier operating parameters
and settings (equalization and attenuation, and ingress detection switch settings) will be displayed.
