DOCSIS Technology Ramps Up Speed

June 22, 2023

Thanks to two recent innovations, DOCSIS technology is bringing more speed to the table. First, DOCSIS 3.1 cable modem termination systems (CMTSs) can now offer more DOCSIS channels than they did just a few years ago. Second, DOCSIS 4.0 cable modems (CMs) can take advantage of those extra channels to provide even faster speeds. DOCSIS […]
