Abstract: An OLT comprises: a memory; a processor coupled to the memory and configured to: determine each of a plurality of channels associated with an ONU, select a first channel from among the channels, and generate a first message comprising at least one field instructing enablement or disablement of the first channel; and a transmitter coupled to the processor and configured to transmit the first message to the ONU. A method implemented in an OLT, the method comprises: determining each of a plurality of channels associated with an ONU; selecting a first channel from among the channels; generating a first message comprising at least one field instructing enablement or disablement of the first channel; and transmitting the first message to the ONU.

Abstract: An adaptive heat dissipation apparatus is provided, including two or more chamber walls forming a chamber volume having a first open side and a second open side, a heat source positioned at the first open side of the chamber volume, a heat conducting surface positioned at the second open side of the chamber volume, and a thermally-expansive material occupying a predetermined portion of the chamber volume. The thermally-expansive material expands to substantially fill the chamber volume at an ambient temperature above a predetermined temperature threshold and conducts heat from the heat source to the heat conducting surface. The thermally-expansive material contracts to leave an air gap when the ambient temperature is below the predetermined temperature threshold.
