The receiver will not function below this DC
level which is equal to -10 dBm.
• The optimum light level input is -10 to -2
dBm.
• For every 1 dBm change in optical input
power, the RF output will change by 2 dB.
• Excessively high light input levels (> -2
dBm) will cause distortions and/or damage
the photo diode.
