The power reflected by the CVBG after the PBS is measured at 8.16mW (powermeter without AA-OD1 filter)

The power injected in a unpolarized fiber is about 5.4mW

The power injected in the EOM fiber (to be directly connected to the amplifier) is 1.5mW (1.72mW if a lambda/2 is added and 1.76mW if both lambda/2 and lambda/4 are added)

One has to check the spectrum after EOM to be sure it is clean (without CW peak)
