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 ecient, 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 ecient 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
oered 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.
