Chapter 1: Overview of the DBC-1200
The Technetix DBC-1200 amplifier is an innovative ‘crossover’ design which provides a field upgradeable solution to
deep fibre/fibre to the last amplifier (FttLA). Its RF function can be configured for use as single, dual or triple output
device (with or without an internal splitter/directional coupler).
The amplifier provides reverse path transmission with a hybrid amplification stage.
Forward and return path attenuation can be adjusted with electronic attenuators. Electronic equalisers are available for
forward and return path equalisation. Cable simulation is provided by a JXP module.
The DBC-1200 has a highly ecient, long-life, switch-mode power supply to provide the power.
Gas tubes at the input and output ports protect the RF circuits in the event of lightning or mains power surges.
Benefits:
■ Full digital control and setup with integrated ALSC
■ Improved intermodulation distortion performance - innovative GaN technology operates to 1218 MHz
■ Energy ecient hybrid technology provides more gain from 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
■ On-board ingress detection facility provides an option to apply -6 dB or -40 dB of return path attenuation via a
simple transponderless protocol (FSK).

Chapter 3: Installing the DBC-1200
3.1 Housing mounting
There are two options for mounting the DBC-1200 amplifier:
3.1.1 Using side brackets
The unit is supplied with 2 x ‘L’ brackets that are attached onto the side of the unit using the 2 x 6mm threaded 10mm
long countersunk screws provided (see the pictures below). Once the brackets are attached, the amplifier can be
oered up to the mounting location to mark the bracket cut outs onto the mounting surface ready for holes to be
made for the mounting bolts/screws. The amplifier can then be attached to the mounting surface using appropriate
fixing devices.

7Technetix Group Limited Rev.1._0.1_0217
3.1.2 Rear mounting direct to cabinet back panel
For mounting directly onto a cabinet back panel, use the rear 6mm bolt holes with 2 x 6mm threaded bolts (figure 1). Do
not use fixings that are longer than 6mm, otherwise they may protrude through the back board. The bolt total length
dimension to be used is 6mm + back board thickness dimension + washer thickness dimension.

3.2 Installing coaxial
1. Cut the connector pins to a length of 28mm for PG11 threaded connectors (figure 2). When using 5/8”
threaded connectors and PG11 to 5/8” reducing rings, add 2.5mm to the connector pin length = 30.5mm.
PG11 connector: pin length from connector housing
shoulder to pin tip = 28mm
(Figure 2)
Use the internal pin length guide to check the correct
pin length. Place the PG11 connector housing shoulder
against the amplifier housing lip to check the pin length.
2. Tighten the connectors into the housing in accordance with the connector manufacturer’s specification.
The maximum torque force for the PG-11_5/8 adapter ring is 20 Nm.

9Technetix Group Limited Rev.1._0.1_0217
3.3 Closing amplifier
Use a 6mm hex key to tighten the four lid securing bolts.
Next, using a 10mm socket, hand tighten the lid bolts in the following sequence: 1 - right hand bolt; 2 - left hand
bolt; 3 - bottom bolt; 4 - top bolt. Then, using a torque wrench set to a torque value of 5 Nm, go round 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 down to within the correct parameters when installed
as recommended.

3.4 Configuring the PSU
The DBC-1200 has the following power supply options:
1. Local powering is possible on RF port 3 (bypass port) using a power inserter
2. Remote powering, maximum AC power passing = 10
See page 27 for removal/installation of PSU unit.
Powering routing
Fusing (power directors)
Referring to the network design documentation, remove any fuses not required for passing power.

2. Use a true RMS digital voltmeter to confirm AC power is present on the incoming power port in accordance
with the network design drawings. The voltage should be within the amplifier specification and the network
design drawing calculation.
3.5 Powering up the amplifier
1. When the device is configured 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 earthing/grounding wire (in
accordance with local electrical installation regulations) on the right hand side of the housing.

12Technetix Group LimitedRev.1._0.1_0217
(Figure 5)
3. Install the fuse (power director) ensuring it is fully inserted into the fuse holder in the relevant port for incoming AC
power. Check that the amplifier DBDCM module LED (DBDCM-Ax = red, DBDCM-Cx = green) and the PSU LED.

13 Technetix Group Limited Rev.1._0.1_0217
3.6 Downstream configuration
Note: a range of input splitters is available up to a value
of 1.2 GHz (1.2 GHz splitter item code: 19005718)
1. Referring to the network design documentation,
configure the input bypass splitter by installing a 0
pad/jumper into the top three holes of the five holes
(to pass all RF into the amplifier). Alternatively, install
a relevant 2-way splitter or directional coupler.
Note: bottom two holes should be exposed with 0 pad/
jumper in top three holes.
2. Ensure that the directional coupler is installed the
correct way round so that the through leg is passing RF
signal into the correct path as required by the network
design documentation.
With the selector installed as shown, pin 5 is to the top
so the through leg is to RF Port 3 and pin 5 is passing
RF into the amplifier.
Pin 5 is the tap leg.
Output splitter selector
Referring to the network design documentation, configure
the output splitter by installing a 0 pad/jumper into the
right-hand three holes of the five holes (to pass all RF
into Port 1) or the three left- hand holes (to pass all RF into
Port 2). Alternatively, install a relevant 2-way splitter or
directional coupler.
Output selector shown with a 0 pad/jumper installed into
the right-hand three holes, passing all output RF into Port 1
When installing a directional coupler, ensure that it is
inserted the correct way round so that the through leg is
passing RF to the correct port as required by the network
design documentation.

14Technetix Group LimitedRev.1._0.1_0217
3.7 Downstream activation
Connect a spectrum analyser to the input -20 dB test point, then measure and record the RF pilot frequencies’
input levels as per the design drawings.
Note: ensure all amplifier ports are connected to a 75Ω terminated load so that the RF test instrument readings
are correct.

■ Next, carry out the following:
Note: steps 1 to 3 can be set on the bench if the amplifier is powered up before it is deployed.
1. When the USB is connected the software will autodetect the connected amplifier. This enables the BLL
application to connect to the DBDCM module. Once the amplifier communication is established, the amplifier
type name will appear at the top left of the application (this process is carried out automatically with the latest
versions of BLL software - please specify version numbers).

18Technetix Group LimitedRev.1._0.1_0217
2. Set the Amplifier Type to its respective application followed by the Diplexer Type and the upper equaliser hinge
point - End Frequency.
Once these values are set in the application, click on ‘Send to amp’ to set these values electronically.
3. The downstream Inter-stage equaliser and Inter-stage attenuator can be set as required by the network/system
design documentation in two ways. You can set them in the amplifier schematic inter-stage tabs or in the table to
the right of the application screen (see the screen shot below). Once the values are set in the application, click on
Send to amp to set these values electronically.
