Abstract:
1. A hybrid fiber/coax network, comprising: a head end; at least one optical distribution node coupled to the head end over at least one fiber optic link; at least one coaxial cable link, coupled to the at least one optical distribution node, that receives upstream digital data from and that provides downstream digital data to a plurality of modems; wherein the at least one coaxial cable link is shared by at least two of the plurality of modems for data communication; wherein the upstream digital data is transmitted over the at least one coaxial cable link on at least one modulated carrier; and wherein the optical distribution node has a bi-directional data path that includes: a data concentrator coupled to the laser transceiver; and a node modem coupled between the at least one coaxial cable link and the data concentrator that demodulates upstream digital data for the data concentrator and that modulates downstream digital data for transmission over the coaxial cable link.
