DOCSIS 3.1 technology also includes some new energy management features that help the cable industry to reduce its energy usage, and the DOCSIS-PIE algorithm to reduce buffer bloat. DOCSIS 3.1 suite of specifications now support capacities of up to 10 Gbit/s downstream and 2 Gbit/s upstream. The first release goes back to October 2013, although this technology was updated several times since.
Normally, it is used by many cable television operators in order to provide Internet access over their existing hybrid fiber-coaxial infrastructure.

FTTH is a Point to MultiPoint (P2MP) network architecture, DOCSIS 3.1 is a transport mechanism. So, first of all, let’s clarify that this should not be a question of FTTH – Fiber To The Home vs. Should I go for FTTH or DOCSIS? This question may be in your head when building innovative networks and providing the best service to your customers.
