Abstract
In a power splitting passive optical network, TDM/TDMA communication is employed for downstream/upstream transmission over a fiber. A framed structure is used for the downstream transmission from an optical line card (OLC) at the network end to a plurality of optical network units (ONUs), which are each connected to end user equipment. A framed structure is also employed for upstream burst transmission from the plural ONUs to the OLC. In the upstream direction each ONU transmits at most one burst per frame that includes a header and a payload containing a variable number of bytes that is adjustable on a continuum. The length of each payload in a burst transmitted upstream by an ONU is determined as a function of the bandwidth requirements of the end user equipment connected to that ONU as well as the bandwidth requirements of the end user equipment at the other ONUs.
