CableLabs Opens DOCSIS 3.1 Certification Tests

CableLabs this week announced that the company has opened the door to DOCSIS 3.1 product certification submissions, meaning that gigabit speeds (and more) over cable are one step closer to fruition. The DOCSIS 3.1 standard provides top speeds of 10 Gbps down, 1 Gbps up -- and will pave the way toward a growing number of cable operators offering gigabit service over coaxial starting early next year.

"We are very excited that cable network operators are now priming their networks for DOCSIS 3.1 readiness through field testing and trials," notes the group. "Early results show that the utilization of high order DOCSIS 3.1 modulation schemes will significantly increase network efficiency."

A growing number of cable operators are currently conducting trials. Earlier this week, Comcast stated it has been testing DOCSIS 3.1 gear since March, and hopes to have the standard fully deployed (and gigabit speeds available) to the company's entire footprint in two to three years.

Commercial grade modems, gateways, and cable modem termination systems (CMTSs) should then start to appear early next year, followed by relatively quick and inexpensive upgrades by carriers. What these next-generation DOCSIS 3.1 speeds will cost you, the consumer, isn't yet clear.

Coax

Still has some life left in it, and with these advances will continue to do well. The single biggest advantage is that coax is providing decent speeds at realistic distances.

Technology and Caps

I like that the tech. is getting faster. I hope this will enable ISP's to offer more symmetrical services in the future.

Also, What is the point of the faster speeds when you have a 250GB cap or smaller and are not able to use the service to its full extent with out having a $100,000 internet bill. This will be just like all the the astronomical cell phone bills stories all over again.

You notice now that we never hear of the $10,000 cell phone bill or the $80,000 cell pone bill anymore?

Big difference in just upgrading the CMTS vs the entire plant

You have a lot of operators commited to D 3.1 rollouts, but how many are just upgrading the existing CMTS (line cards / firmware) or installing new CMTS's, vs. a plant upgrade?

How many 5-42 MHz upstream networks will really be upgraded to 88 MHz or 216 MHz?
How many 860 MHz plants or lower will actually be upgraded to 1200 MHz or 1800 MHz, supported by the spec?

Fitting D3.1 into the current limited spectrum isn't going to net you 10 gig. Sure it will be better as long as there is available bandwidth freed up by the elimination of analog carriers, IPTV migration or SDV.

How about ..
