Several point to check GR/IR power (AOM setting)

Yuhang and Aritomi

Power reference form

GR power before green EOM 200mW
GR power before AOM 36mW
GR power before MZ 152mW
GR power after AOM 12.6mW
IR power before ND filter 20mW
IR power after ND filter (before IRMC) 4mW
IRMC transmission 1.7mW

We set the power after AOM by changing the AOM modulation depth. The maximum RF signal we should give to AOM is 30dBm(1W). The signal is generated from a signal generator then pass through a RF amplifier(amplify 32dB). So the maximum RF signal power we should generate should be -2dBm. Then we measured the GR power after AOM while changing AOM modulation depth(see attached form).

AOM modulation depth Green power (injected to FC)
30dBm 28.2mW
29dBm 28.5mW
28dBm 27.8mW
27dBm 26mW
26dBm 23.5mW
25dBm 20.7mW
24dBm 17.8mW
23dBm 15.11mW
22dBm 12.65mW
