Unlocking Full Duplex DOCSISĀ® 3.1 Architecture With DPD And 75-Ohm CATV Switches

The CATV industry is looking to set new standards for the next generation of cable ecosystems, including the Full Duplex (FDX) DOCSIS 3.1, which promises to deliver 10 Gbps data rates upstream and downstream on existing hybrid fiber-coaxial (HFC) systems. Achieving FDX will require highly linear devices enabled for digital predistortion (DPD) — including 75-ohm CATV switches. This article explores how DPD works in CATV optical nodes, as well as some considerations for selecting the right switch for each application. Download the full paper for more information.
