An optical access network (202) and method for transmitting optical data in the network (202) utilizes an interleaved polling scheme to efficiently use the available bandwidth of the network (202). The use of the interleaved polling scheme allows a central terminal (204) of the network (202) to dynamically allocate upstream bandwidth from remote terminals (206,208,210) of the network (202) to the central terminal (204) in response to the amount of data that is waiting at the remote terminals (206,208,210) to be transmitted to the OLT (204). In one embodiment, the optical access network (202) is based on Passive Optical Network (PON) technology. In another embodiment, the optical access network (202) utilizes Ethernet protocol to encapsulate data in Ethernet frames for transmission. Thus, in these embodiments, the optical access network (202) includes all of the advantages associated with the PON technology and/or the Ethernet protocol. |
