What is a DOCSIS cable modem?

DOCSIS stands for “Data Over Cable Service Interface Specification.” It’s the protocol that lets an ISP provide internet service through a coaxial cable. It just means that your modem can provide broadband internet access.

How does a DOCSIS 3.0 cable modem work?

DOCSIS 3.0 allows you to combine the channels on a cable modem, thereby increasing access speed. Up to 16 forward and 8 reverse channels are combined. Prior to DOCSIS 3.0, the bandwidth per user in a downstream channel was approximately 25 Mbit/s; in an upstream channel, it was no more than 10 Mbit/s.

Is DOCSIS better than fiber?

Fiber carries much higher-frequency signals than coax does. DOCSIS 3.1 uses frequencies up to 1.2 gigahertz, but common fiber-optic cables carry light in the infrared spectrum between 200 and 350 terahertz. A typical fiber-optic cable has around 10,000 times more usable bandwidth than a typical coaxial cable.

What is a 24×8 modem?

A 24×8 modem has 24 downstream channels and 8 upstream channels, for theoretical speeds of 912 Mbit/s downstream and 216 Mbit/s upstream. The real-world performance of a 24×8 cable modem is around 60% of its rated speed. This means it should be suitable for ultra-fast cable connections.

Is DOCSIS 3.1 fast?

And that’s where DOCSIS 3.1 comes in. DOCSIS 3.1 standard supports up to 10 Gbps download and 1 Gbps upload speeds which is up to 10x faster than DOCSIS 3.0. Currently cable ISPs are offering Gigabit Internet service using DOCSIS 3.1 technology.

What is DOCSIS vs Ethernet?

Docsis is whats coming over the cable to your modem. Its literally just the spec for data over cable. As for Ethernet WAN you would connect the WAN port of your dedicated router to the ISP modem in bridged mode.

Does DOCSIS 3.1 work with fiber?

The latest version, DOCSIS 3.1, allows up to 10Gbps downstream and 1Gbps upstream, which to-date had only been possible with a fiber optic connection, and can, with few infrastructural changes, be easily deployed over existing infrastructure.

Is Docsis 3.1 future proof?

Hitron’s CODA DOCSIS 3.1 Cable Modem will future-proof your Internet connection because it can deliver the speeds that your ISP is providing today as well as delivering the higher speeds up to 10 Gbps of tomorrow.

Is a modem with more channels better?

Modems with more channels usually have better hardware overall, and speeds of about 60% of the rated performance are likely. This means a 16×4 modem is more than powerful enough for a low or mid-tier internet connection. Usually, a 16×4 cable modem is used by ISPs for speed tiers of around 300Mbps.
