for distribution of the signal. Equalizers are available in 2dB steps from 0 to 10dB. The receiver is
preset 0dB slope output before sales.
3. Output Amplifier
There is a 350MHz power-double hybrid with 24dB gain.
4. Optical Power Test Point
The optical power test point inside the receiver is scaled at 2 Volts per million watt and provides an
indication of received optical signal power. The expected DC voltage at this test point should
between 0.5V and 2.0V.
