Abstract (en)
[origin: WO02097476A2] A point-to-multipoint passive optical network transmits downstream data from an optical line terminal (OLT) to multiple optical network units (ONUs) in variable-length packets and upstream data from the ONUs to the OLT in variable-length packets utilizing time division multiplexing with variable-length time slots to avoid transmission collisions. In an embodiment, the system further includes a time slot controller in communication with the OLT and the ONUs for changing the length of the ONU-specific variable-length time slots in response to upstream traffic demand from the ONUs. In a further embodiment, the time slot controller includes logic for increasing the length of a first ONU-specific time slot in response to an increase in upstream traffic demand from a first ONU, the first ONU being one of the ONUs. In a further embodiment, the time slot controller includes logic for decreasing the length of a second ONU-specific time slot in response to the increase in the length of the first ONU-specific time slot. In an embodiment, the variable-length downstream packets and the variable-length upstream packets are formatted according to IEEE 802.3.
