Chapter 1: Overview of the DBD-1200
The Technetix DBD-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 DBD-1200 has a highly efficient, 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 efficient 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).
