Burst Mode transmitters are active a small percentage of the time (low duty cycle) and the Burst Time can vary from one Burst Period to another. The SPGU-P3412-SB2DA monitors the Tx Burst Mode power and the photo detector monitor current (BIAS). The DDMI WARNING and ALARM memory positions and addresses are compliant with the SFF 8472 Rev 10.2 specifications. Mechanical Dimensions
