Chapter 1: Overview of the DBC-1200S
The Technetix DBC-1200S strand mount amplifier is an innovative “crossover” design
which provides a field upgradeable solution to deep fiber/fiber to the last amplifier (FttLA)�
The RF function can be configured for use as a two output device (with or without an internal
splitter/directional coupler)�
Designed using energy ecient GaN (gallium nitride) technologies, the DBC-1200S oers a functional
upgrade path for the majority of compact amplifiers from other manufacturers by:
■Consuming less power for the same operational gain
■Providing a similar or smaller physical footprint
■Harnessing GaN technology to provide class-leading forward and return path gain, duplicating
or improving on the performance of existing units
The DBC-1200S provides reverse path transmission with a hybrid amplification stage�
Forward and return path attenuation can be adjusted with electronic attenuators, with electronic
equalizers available for forward and return path equalization� The cable simulation may be provided
by a suitable JXP plug-in module�
The DBC-1200S has a highly ecient long-life switch-mode power supply to provide the powering
modes required for the modules used�
Gas tubes at the input and output ports protect the RF circuits in the event of lightning
or mains power surges�

2.2 Housing mounting
There are two options for mounting the DBC-1200S amplifier� The first option is to use the strand
mounting clamps supplied, as shown in example 1� The second option is to use the rear 0�25” (6 mm)
threaded holes on the back of the unit, as shown in example 2�
Using strand clamps
The unit is supplied with two strand clamps that are attached using two 0�25” (6 mm) threaded 0�4”
(10 mm) long countersunk screws on to the top of the unit (see following pictures)� Once the strand
clamps are attached, the amplifier can be oered up to the strand mounting location and clamped
into position�
Example 1 Example 2

Rear mounting direct to cabinet back panel
For mounting directly onto a cabinet back panel, the rear 0�25” (6 mm)bolt holes can be used with
two 0�25” (6 mm) threaded bolts (see following picture)� When using this method of mounting, ensure
that the bolts’ threaded part are no longer than 0�25” (6 mm) in length when protruding through the
back board on which the amplifier is mounted� The bolt total length dimension to be used is 0�25”
(6 mm) + back board thickness dimension + washer thickness dimension�

2.3 Installing coaxial connectors
Input/output cable connectors
1� Cut the 5/8” threaded connector pins to a length of 1�2” (30�5 mm)� The pin length
should be measured from the connector housing to shoulder to the pin tip�
Use the internal pin length guide
to check the correct pin length�
Place the 5/8” connector housing
shoulder against the amplifier
housing lip and check the pin length
against the guide�
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�

04/2019 - AE/V1.16 14
Technetix Group Limited
2.4 Closing amplifier lid
To close the amplifier lid, first use a large Phillips head screwdriver to make the six lid-securing bolts
hand tight� Next, using a 0�43” (11 mm) socket, hand tighten the lid bolts in the following sequence:
1 – left-hand bolt; 2 – right-hand bolt; 3 – top bolt; 4 – bottom bolt; 5 – bottom bolt; 6 – top bolt�
Then, using a torque wrench, set to a torque value of 45 inch pounds (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 within parameters
when installed as recommended�

2.6 Powering up the amplifier
After any bench pre-configuration required by the network design is done, and once the amplifier is
mounted into the network location, temporarily remove the fuses� Connect the RF cables to relevant
RF ports, and connect the earthing/grounding wire (in accordance with local electrical installation
regulations) on the housing (see following picture)�
Using a true RMS digital voltmeter, confirm AC power is present on the port where incoming power is
present in accordance with network design drawings (see following picture)� Voltage should be within
the amplifier specification and network design drawing calculation�

2.7 Downstream configuration
RF input/output splitters
Input bypass splitter selector
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: Left-hand two holes exposed with 0 pad/jumper in right-hand three holes.
2� When installing the directional coupler, ensure that it is inserted the correct way round so that the
through leg is passing RF into the correct path as required by the network design documentation�
Pin 5 is the tap leg�

04/2019 - AE/V1.16 18
Technetix Group Limited
Output splitter selector
Referring to the network design documentation, configure the output splitter by installing a 0 pad/
jumper into the upper three holes of the five holes to pass all RF to Port 1, or use the three lower holes
to pass all RF to Port 2� Alternatively, install a relevant 2-way splitter or directional coupler�
When installing the directional coupler, ensure that it is in the correct way round so the through leg
is passing RF to the correct port as required by the network design documentation for location of
amplifier installation�
With the output selector installed as shown in the picture below, pin 5 is on the bottom, so RF Port
2 has tap leg and RF Port 1 has through leg of selector� To reverse the selection, install the output
selector the other way round�

2.8 Downstream activation
Connect a spectrum analyzer 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.
