Methods and systems for an optical line termination including instructions stored on a computer-readable medium, the instructions including a digital diagnostic table, and a plurality of entries within the diagnostic table, wherein a first entry is associated with a first optical network unit, the first entry including at least one setting for performing burst mode digital diagnostic processes using a first burst mode transmission received from the first optical network unit.

Burst mode digital diagnostic and control for passive optical network receiving

An AC differential connection assembly between a trans-impedance amplifier and a post amplifier for burst mode receiving comprising means for coupling a differential output of the trans-impedance amplifier to a differential input of the post amplifier, the means for coupling comprises a coupling capacitor assembly; and a switching circuit coupled across the differential input of the post amplifier, the switching circuit having an 'on' state with low impedance and an 'off' state with high impedance; wherein during burst mode receiving, the switching circuit is in the &#x2018;off&#x2019; state and the coupling capacitor assembly having a time constant to maintain a stable DC level such that a payload is received accurately by the differential input of the post amplifier; and during an idle period, the switching circuit is in the &#x2018;on&#x2019; state and the coupling capacitor assembly having a time constant to recover a DC level of the differential output of the trans-impedance amplifier.
