What You Should Know About DOCSIS 3.1

  • DOCSIS 3.1 is the fastest cable modem standard, supporting Internet speeds of many gigabits per second.
  • Actual performance depends on your service and the devices sending data through the MB8611cable modem.
  • Even if you don’t have 3.1 services now, you can benefit from the 32×8 3.0 capability that’s also built into the MB8611.

What To Know About The 2.5 Gbps Ethernet LAN Port

  • This very fast Ethernet LAN port helps you get maximum performance from high-performance routers. If you subscribe to a service above 1 Gbps, a LAN port of only 1 Gbps can reduce actual speeds. Some cable modems aggregate two Ethernet ports to address this problem, but a single 2.5 Gbps LAN port is far superior to LAN port aggregation.
  • This cable modem also supports 1 Gbps and 100 Mbps LAN supports, as a result, it’s fast and flexible.
