The first pathway passes a forward signal to the forward output in a first frequency range. A return pathway is coupled to the forward pathway. The return pathway has a fiber optic output. The return pathway passes a return signal to the fiber optic output in a second frequency range, wherein the first frequency range is higher than the second frequency range. A cancellation circuit is coupled to the forward pathway and the return pathway. The cancellation circuit separates and isolates the forward signal from the return signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adjustable return bandwidth in CATV nodes including RFoG optical units (R-ONU)","description":"A Cable Television (CATV) node circuit has a forward pathway having a fiber optic input and a forward output.
