Abstract
A hybrid fiber-coax network may replace an analog forward link with a digital optical forward link between a converged cable-access platform (CCAP) and node, which may allow for improved data-throughput rates on the network. Replacing the analog forward link with the digital optical forward link may allow for a greater distance between a headend and the node. Further, the digital optical forward link may improve link modulation error ratio (MER), which, when combined with advanced headend equipment, may enable a cable modem to support the high-order modulation profiles (e.g., profiles included in DOCSIS 3.1).
