Abstract
The differences in the power received from multiple optical network units connected to an optical hub may exceed an allowable dynamic range. The dynamic range may be reduced by determining the power received at the optical hub from each optical network unit and adjusting the power transmitted from one or more optical network units to reduce the overall dynamic range. For each optical network unit, the hub may determine the received optical power in an upstream signal from the optical network unit and receive a digital representation of the transmitted power. The hub may determine to adjust the optical power sent from one or more of the optical network units to reduce the dynamic range. The adjustments to the optical powers at the optical network units may be performed by sending commands from the optical hub to each adjusted optical network unit via a downstream signal.
