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.
  • Compatible with 3.1 and 3.0 services, the MB8611 supports Active Queue Management (AQM), which significantly reduces lag and delivers more responsive gaming, video conferencing, and more.

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.
