Do you need Docsis 3.1 for gigabit?
For cable internet, yes you do need it, as it support gigabit download speed. For fiber, however, it is not needed, as fiber internet needs fiber-optic modem.
What is the best modem for high speed Internet?
We tested the ARRIS SURFboard SB8200 DOCSIS 3.1 and believe it to be the best modem for high speed Internet.
What does Docsis 3.1 mean?
Docsis means Data Over Cable Service Interface Specification. It is a standard for transferring data over the cable system. And Docsis 3.1 is a new generation of technology made for high-speed connections. It can support data transfer up to 10 gigabits per second downstream and 1 gigabit per second upstream over cable, which was only possible over the fiber-optic network.
Is a Docsis 3.1 modem worth it?
If you have a gigabit internet plan, then Docsis 3.1 modem is the best option. Even if you don't have a gigabit internet plan, it is still the best option since many ISP declared DOCSIS 3.0 end of life. It means some ISP may not allow DOCSIS 3.0 modem activation for new accounts. And some DOCSIS 3.0 modems cost the same as DOCSIS 3.1 modems, so there are no financial benefits to not using a DOCSIS 3.1 modem.
Difference between Docsis 3.0 and 3.1 modem?
The differences between 3.0 and 3.1 comes down to speed, and the ability to use simultaneous channels. Docsis 3.1 comes with 10Gbps of download speed, 1Gbps of upload speed, and 1.89 Gbps per 192 MHz channel. However, Docsis 3.0 is only capable of 200 Mbps upload, 1 Gbps of download speed, and only 42.88 Mbps per 6 MHz channel. In short Docsis 3.1 has much higher speed, throughput, and uses data spectrum more efficiently than Docsis 3.0.
Are the Docsis 3.1/Gigabit cable modem backward compatible with current provider?
Yes, Docsis 3.1 modems are backward compatible with Docsis 3.0, which is your existing cable modem if you didn't upgrade already.
