   The NETGEAR Nighthawk CAX80, a high performing modem/router combo that works with internet plans up to 1200 Mbps, has similar specs as the Comcast/Xfinity-only Motorola MT8733—DOCSIS 3.1, 2.5 ...

   DOCSIS 3.1 uses channel bandwidths of up to 192 MHz in the downstream. [14] Upstream: DOCSIS 1.0/1.1 specifies channel widths between 200 kHz and 3.2 MHz. DOCSIS 2.0 & 3.0 specify 6.4 MHz, but can use the earlier, narrower channel widths for backward compatibility. DOCSIS 3.1 uses channel bandwidths of up to 96 MHz in the upstream. Modulation:

   DOCSIS 2.0 added support for S-CDMA PHY, while DOCSIS 3.0 added IPv6 support and channel bonding to allow a single cable modem to use concurrently more than one upstream channel and more than one downstream channel in parallel. Virtually all cable modems operating in the field today are compliant with one of the DOCSIS versions.

6. DOCSIS Set-top Gateway - Wikipedia

   en.wikipedia.org/wiki/DOCSIS_Set-top_Gateway

   A cable modem that is unable to acquire an upstream channel will give up and resume scanning for new channels. Likewise, persistent upstream errors will cause a cable modem to "reinitialize its MAC" and scan for new downstream channels. This behavior is appropriate for traditional cable modems, but not for cable set-top boxes.

7. Radio frequency over glass - Wikipedia

   Additionally, higher-performance RFoG systems not only support DOCSIS 3.0 with bonding, but also enable 64 quadrature amplitude modulation (QAM) upstream transmission in a DOCSIS 3.0 bonded channel, dramatically increasing return-path bandwidth. Improved operational expenses; RFoG brings the benefits of a passive fiber topology.
