Much of the specifics are left to the user as any system can. Googling "common pin" indicates it has some relation to ground, but I didn't find a definitive answer. I suspect that the "2" pin on the laser diode is meant to go to ground, since pin 1 is for the photo-diode and pin 3 is for the cathode, but the datasheet doesn't explicitly mention this.

The noise performance of an erbium-doped fiber amplifier (EDFA) is characterized by modeling optical amplifiers as four-level or three-level systems. The gain and noise performance are then examined under forward and reverse pumping.
