Forward Band Amplification 2-Way and 4-Way Path Description
The RF amplifier module provides all forward signal amplification outside the
optical receiver modules in the GS7000 Node.
The 4-way segmentable launch amplifier contains four independent forward
amplification paths, each having one input near the center of the amplifier module
and one, two or three outputs at one end of the amplifier module. Each of the
forward paths is comprised of the forward configuration module, an input gain
block, a frequency response trim circuit, a thermal compensation circuit, an
inter-stage pad, an inter-stage gain block, a plug-in linear equalizer an output pad,
an output gain block, a diplex filter, a bi-directional 20 dB down forward test point,
and finally an AC bypass circuit.
The 2-way segmentable launch amplifier contains two independent forward
amplification paths, each having one/two inputs near the center of the amplifier
module and two/three outputs at one end of the amplifier module. Each of the
forward paths is comprised of the forward configuration module, an input gain
block, an inter-stage pad, a thermal compensation circuit, a frequency response trim
circuit, a plug-in linear equalizer, an inter-stage gain block, a fixed on board
equalizer, an output pad, an output gain block, a diplex filter, a bi-directional 20 dB
down forward test point, and finally an AC bypass circuit.
