There are 5 modems that have been certed, but none are for sell yet/on comcast's list. Look later this year.

Yes, see: »Re: [DOCSIS] What is docsis 3.1?

Don't know how many (or if any) of those five are targeted for retail sale, or just for lease by MSOs, though.

One other D3.1 modem that is being targeted for retail sale is the ARRIS SB8200: »Re: [Connectivity] What is docsis 3.1?

Also more details here: »Arris announces DOCSIS 3.1 modems

Not sure if it has been certified by CableLabs yet though.

This is why I still recommend going with a 16x4, 24x8, or 32x8 D3.0 modem. Who knows when or if they're ever going to come to the retail market. As others on the forum have said, the system still going to be operating in mixed D3.0/D3.1 mode for quite a while. It's not going to be a big dramatic overnight change that suddenly causes all D3.0 devices to become obsolete like the 2009 analog to digital switchover did to OTA analog tuners. It's going to be a meticulously planned, long, drawn out process that will probably take years to fully implement in every market.

Well said!

There's no magic 'cutover' that's going to happen, since D3.1 will use the same lines as D3. An upgrade to the cards at the CMTS to handle 32 downstream channels is the core requirement. A 16- or 24-channel modem will still work just fine.

I'm not 100% sure about models for retail sale. I have had the opportunity to see Comcast's D3.1 gateway and I'm excited to see it in customers' homes as soon as it's ready.

John - Do you know if that gateway has obtained CableLabs certification yet? I guess that was not required for "trial" use so far, though.

I'm doubtful since the majority of residential users wouldn't have equipment that has an SFP+ port, however it might be possible for a business geared model to be released which does.

An SFP+ port is just a port for an optic or copper Ethernet adapter of the users choice. The adapters run 50-250 each depending on the type.

And so long as they make sure it's capable of running at just gig in addition to 10gig they could ship it with a GLC-T in it, then if the user want to connect it at 10gig all they'd have to do is get the right adapter and plug it in.

Comcast's own D3.1 modem... I think that is only a temporary modem. If I remember correctly they said that in an interview. They will provide "regular" modems at a later date.

Well, it's more than just a "temporary modem," it's a major D3.1 gateway box:

From: »www.multichannel.com/new ··· y/390410

According to [Comcast's EVP and CTO Tony] Werner, the new D3.1-powered gateway will also feature gigabit WiFi, support IP video, and integrate home automation and security capabilities. It's also the first Comcast device to integrate home networking control and monitoring software that the operator acquired in 2014 via its purchase of PowerCloud Systems. It's also equipped with RDK B, a new flavor of the Reference Design Kit, a preintegrated software stack, that can be applied all-purpose gateways.

I was thinking about that. Jorge Salinger talks about a test modem (8:00). It might be a different modem.

OK, yeah, I see what you mean.

Jorge Salinger said they had hundreds of those early "non-gateway" modems made by an industry partner for their initial D3.1 field testing during early 2015.

He seems to indicate that a gateway was currently "under development" though, for use with consumer trials to start this year (2016), like in the Atlanta area now: »Email stating gigabit is on the way to Woodstock, GA

i don't care about the channels per se. i care about the docsis 3.1 and active queue management or AQM which will help bufferbloat and stuff like that. I am not looking at higher speed. I am looking at better handling of queueing which would make my connection a little better if you know what i mean. If i am correct none of the modems today have AQM at least on the consumer side correct me if i am wrong.

I'm thinking AQM wouldn't be enabled until the network is running in pure D3.1 mode later on.

I believe that there will be both a gateway and a stand-alone modem. Not sure if this is what you mean.

OK, that actually makes sense, as the Light Reading article about it had this picture of two different models, but called them both "gateways": »Re: DOCSIS 3.1 Field Trials now in progress

IE 3-5 years after widespread adoption maybe.

They're only even in the early phase of killing off 4x4 D3 modems and there are still posts by people using D2 modems on this forum.

so before pure D3.1 can happen D3.2 or D4 might be in the launching phase due to all those people that haven't upgraded their still working older tech modems.

At this time, these are the CableLabs certified DOCSIS 3.1 modems. They are listed in order as on CableLabs. I have included links to modems I could find info on with specs and pics of those. ( The Sagemcom model name is shown as listed on CableLabs, not typo).

wtf is going on with the case on the Askey one? Looks like it's mounted inside half a block of wood..... weird. Also, it apparently can only do "PacketCable" voice service using versions 1.0 and 1.5, not 2.0....

That's a 1gig GLC-T.

So as I said they could ship it with that and have the actual port be a SFP+ port so the GLC-T could be swapped for a 10g SFP+ module. (which so fat there aren't any RJ45 SFP+'s there are 10Gbase-T interfaces but not on SFP+'s.
