SYSTEMS AND METHODS FOR BROADBAND TRANSMISSION OF SIGNALS

摘要

Systems and methods which facilitate broadband transmission of signals using a delivery point tuning technique to provide a extended frequency passive optical network (EF-PON) are shown. Embodiments provide an extended frequency optical transition node (EF-OTN) at each of a plurality of delivery points to provide a frequency translation interface between equipment disposed at the delivery point locations and a network utilizing transmission bandwidth which is incompatible with that equipment. The foregoing frequency conversion is preferably transparent to the equipment receiving the network transmissions. Embodiments utilize a single wideband tuner for providing frequency conversion with respect to a plurality of equipment disposed a delivery point. Network head-end modulators are controlled to implement channel grouping such that the signals requested by each piece of subscriber equipment at a delivery point are placed within radio frequency (RF) channels so that each such signal is within the frequency converted band of an EF-OTN tuner.
