Verizon's ONT can do about 600Mbps down and 155Mbps up according to Tellabs. Video is listed as being a different 'channel' on the Tellabs site so I don't know if the video is included in the 600+Mb capacity or if that 600Mb would be for all of the other non-video services they could offer. DOCSIS3 would have to bond quite a few channels to get that throughput. In any event neither Comcast nor Verizon are going to offer services that will saturate DOCSIS3 or the current FiOS ONT any time soon. DOCSIS3 will be plenty to compete with fiber for the foreseeable future.

DOCSIS 3.0 is not gigabit.

Re: Fibre

Neither is Verizon's ONT according to Tellabs who makes at least some of the ONTs Verizon uses (1600 series). Like cable, the fiber in the street isn't the restriction...it's the equipment on each end.

Re: Fibre

True...But with GPON being deployed that will change.
I'm a Comcast user and can't wait for the deployment of 3.0 and all the new services that come along with it like smart home monitoring. 3.0 will be a good thing for the cable industry.

Re: Fibre

And then cablelabs will cert something new to counter it.

But for us, it's what the consumers are actually seeing that matters. Brian Roberts can crow all he wants about DOCSIS3 but I'll believe it when I see it and support it when it's not being followed with more nastygrams to customers who would dare actually use it.

VOD is IP and eats at the 622, and that 622/155 is shared with upto 32 users (more like 8 in real world 1.5-1.25 fibers per family/house, and only 10-20% of users who are passed subscribe).

Re: Fibre

I thought that the network terminal box (622/155) was a per house device.

Remember with a PON (passive optical network), the fiber is split upto 32 customers/families/accounts/houses. Its similar to cable HFC, but the ratios (1:32) couples with thearetically "infinity/32" bandwidth per house makes FIOS/a PON, much much better than HFC.

Fiber Fanboy here! Already have FIOS at 15/2 for $39.95.

Just as Cable goes 16M - FIOS will "Flip the switch" to 30 or 50 Meg. Maybe even symmetrical!!

Look out cable - your technology is limited, based on your wire!

And DOCSIS 3 cable operators will 'flip the switch' too. DOCSIS3 and current fiber HW from the likes of Verizon are similar in capability. The 1600 series ONTs can do around 600Mb down and 155Mb up and with channel bonding DOCSIS3 should be able to do that and possibly more.

Question is which will actually happen first; wide DOCSIS 3 deployment or flying pigs.

They'll NEVER do symmetrical on res service, that would hurt VZs LUCRATIVE biz packages.

Re: Fibre

Why? They don't share availability (in that biz can't get res services). They already have price differences for identical services between res and biz.

Actually, I looked into FIOS for business and the major difference is CSR (committed service rate) - the amount of guaranteed uptime. Basically, you pay for priority service - makes sense.

Poor Local Cable Co.....Verizon will act like Cable's older brother....Verizon will be holding the cookie above Cable's head just enough so cable can't reach it. Now matter what Cabel does, Fiber will ALWAYS be better as it is the wire of the future.

Lol..fanboy's. Good Stuff.

You think you have it all down pat huh? Got some inside info?

Oh yea...Fiber is not a 'wire'. lol

Educate yourself before pushing it.

You might be right on Verizon flipping the swith but with only 122Mbps per 32 customers you can only get close to 4Mbps upload. Verizon will not be doing a 1x32 split to accomplish that. Cable companies are looking at the Docsis 3.0 along with spectrum overlay. A test was completed in Canada a few months ago and they were able to do 142Mbps symmetrical to the customers home.
