Qorvo-Unlocking Full Duplex DOCSIS® 3.1 Architecture with DPD and 75-Ohm CATV Switches
Consumers and the pressure from 5G wireless are pushing cable TV (CATV) providers to step up their game more than in the past. The CATV industry is now on the fast track to setting new standards for the next-gen cable ecosystem, including Full Duplex (FDX) DOCSIS 3.1, which promises to deliver 10 Gbps data rates upstream and downstream on existing hybrid fiber-coaxial (HFC) systems.
But achieving FDX will require highly linear devices enabled for digital predistortion (DPD) — including 75-ohm CATV switches. This blog explores how DPD works in CATV optical nodes, as well as some considerations for selecting the right switch for your application.
