DOCSIS-EuroDOCSIS 3 Cable Modem | DOCSIS 3 was originally released in August 2006 to support IPv6 and to revise the standard to significantly increase transmissions speeds (both upstream and downstream). The original version of DOCSIS 2.0 was revised to enhance upstream transmission speed to support the IP telephony.

DOCSIS-EuroDOCSIS 3 Cable Modem | As frequency allocation band plans differ between U.S. and European CATV systems, DOCSIS standards have been modified for use in Europe which is under the name of “EuroDOCSIS”. Mostly Cable modems are designed to comply with both DOCSIS and EuroDOCSIS. Even though not all the Cable providers are upgraded their technology with the current DOCSIS 3, they still can use the DOCSIS 3 modems which are backward compatible with the DOCSIS 2.0 or DOCSIS 1.0.

The following are some of the Cable modems which are designed with the DOCSIS 3 technology and also backward compatible with the previous DOCSIS version.

Surfboard SB6120 Docsis 3 cable modem

The SURFboard SB6120 supports all DOCSIS 3 features including channel bonding, IPv6, and Advanced encryption feature. It is compliant with DOCSIS / EuroDOCSIS 3 with channel binding of up to 4 downstream channels and 4 upstream channels for data rate transfer up to 100Mbps. DOCSIS 3 supports the next generation of IPv6 IP addressing system. ISPs can remotely manage, monitor and configure the modem using SNMP and TFTP.

The SBG6120 supports Gigabit Ethernet port you can use to connect to the next generation of high performance wireless routers with Gigabit ports.

In Amazon, the Surfboard SB6120 receives positive customer ratings with averagely 4.4 out of five stars with the following attribute details:

The Surfboard SB6120 DOCSIS 3 Cable modem can provide the high-speed internet access for residential user, SOHO, or even for business and enterprise corporate network. Click here for Surfboard SB6120 spec details.

Surfboard 6580 docsis 3 wireless cable modem

Unlike the SBG6120 modem, the Surfboard® SBG6580 integrates the wireless router into the cable modem in a single device. It is Docis / EuroDocsis 3 compliant enables channel bonding of up to 8 downstream and 4 upstream channels delivering the high speed of up to 100Mbps upstream and up to 400Mbps downstream.

The SBG6580 is powered by the wireless N dual band; it is not simultaneous dual band but selectable. It means that the wireless clients with mix operating bands cannot be connected concurrently. The modem router can work either in 2.4GHz or 5GHz band at a time.

The SBG6580 includes four Gigabit Ethernet ports for fast and reliable wired connection to the gigabit-ready computers.

Surfboard SBG6580 receives averagely 3.6 out of five star customer ratings in Amazon with the following attributes:

Netgear Cmd31T docsis 3 cable modemThe CMD31T is the replacement of CM232 DOCSIS 3 cable modem. The Netgear CMD31T-CME31T is DOCSIS/EuroDOCSIS 3 cable modem delivers the high speed up to 108Mbps upstream and up to 200Mbps downstream, supports channel bonding four channels in each direction.

Like the other two Surfboard modems above, this modem support gigabit Ethernet port for high speed connection to the gigabit WAN port of the routers for maximum data throughput such as WNDR4000 N750 router or the premium version WNDR3800 N600. Both routers support gigabit WAN port.

I think this modem is not sold on the public but to the cable service providers.
