Cisco's 1Gbps Concept Cable Modem
Cisco envisions a 10Gbps cable broadband future
by Karl Bode Wednesday 16-Jan-2008 tags: business · hardware · bandwidth · networking
Cisco Systems has worked up a way to make a DOCSIS 3.0 cable modem scream at 1 gigabit per second — and even faster — by delivering the data over an optical network according to MultiChannel News. Cisco software architect Alon Bernstein, in a presentation at the SCTE's Emerging Technologies conference this week, showed a screen shot of a command-line interface for a cable modem delivering upstream throughput of 974,723,228 bits per second.

Practically speaking, it's a 1-Gbps cable modem. "This is something no cable modem can do today," Bernstein said. It's more than 25 times the throughput available with DOCSIS 2.0 cable modems. Bernstein's presentation was titled "A Proposal for DOCSIS 4.0" -- a cable engineer's joke, because a fourth major iteration of the cable modem spec doesn't exist today.

Not to mention that DOCSIS 3.0, which should offer speeds in excess of 150Mbps isn't fully ratified yet and won't see widespread deployment until next year. But a man can dream. Cisco envisions that once DOCSIS 3.0 is deployed, the next step is a future where DOCSIS and passive optical networking fuse to create connections capable of speeds in excess of 10Gbps.

Way Fast for Cable

Just imagine how fast you could hit your ISP data cap with that much speed?

You sure could download from a whole of sources at once

Re: Way Fast for Cable

Cable systems would need to be ALL fiber optic FTTH anyone? Something they are NOT at the moment. And for a LONG time coming.

With that kind of speed you could hit Comcasts hidden cap within a minute lol.

That's what the article says. Basically, it's FTTP, but still allows the Cable operator to manage it at the cable plant using existing DOCSIS management systems.

It looks to me like they're sending the DOCSIS signal over the in-house coax, then using a fiber ONT attached to the house to convert it into light, which sends it over a PON (like FiOS) network distribution system to the headend.

Basically, it's a DOCSIS to PON transceiver. Slick, but not earth shattering. The real key is that they can have a mix of PON fiber customers along side regular old HFC coax cable modems with a common unified management system.

Technically they can do even faster over cable then that. Just need to push the cable to its limits more and get rid of those channels.

Light waves only move at the speed of light in the absent of a medium. Remember, the stars radiate all of these electrical magnetic radiations through space which there is no medium. It propagates via magnetism one it hits a planet.

What an original post. Every time talk of expanding speeds and capacity, someone always has to spout up and say something like "only to hit that cap faster"...

Honestly, it's the most idiotic statement to be heard of all. Faster speeds will ultimately expand capacity which will relieve the need for as tight controls on transfer in the long run. After all, isn't this what everyone wants?

hmm

I read an article on CES about something like this. They stated that the main thing that is stopping cable companies from switching is that there is no equipment that would let them switch over in steps. I think they said it would require hardware that would allow both docsis via coax and the ftth fiber on the same hardware.

If cisco can come out with something like that thats not really expensive they would make tons of money.

Does this mean that as long as they switched the coax to fiber but still used docsis 3 that they can do a 1Gbps cablemodem?

Nevermind, the article states further down this is basically PON using the accounting software that cablecompanies use currently. this is stupid.

Why cant cisco just work on what I said at the begining of my post. Just create a device that allows the node to be both PON and Coaxial Docsis so that the cablecompanies can slowly switch over away from their docsis network.

At $2.50/GB overage charge (as being proposed by my cable provider, Rogers), you'd be charged almost $20/minute at full speed, once you hit the cap.

I wonder who can afford $1200/hour for Internet access?

Yay!

Finally time will come that wide bandwidth have comes here so cable coaxial can take up 1Gbps to beyond 10Gbps so my Linux computer box can eats bandwidth as you can eat all a food after paid a fee one at time.

Yeah... Japan already have 100Mbps and 1Gbps services so that USA have to catch up with other foreign internet countries powers that I assume that USA really sucks at bandwidth speeds I bet that USA will be always at slow lane line and other foreign internet is in fast lane line over USA.

Depends, TimeWarner in Texas has 7Mbps down/512Kbps up, so that when I download, I get around 834KB/s downloading max and something like 61KB/s up.

Cox cable is way too fast than TimeWarner cable... Sometimes I get 20Mbps to 30Mbps stained in a early morning only.

10 years ago, I was looking foward to ADSL showing up so I could improve on my years of painful 128k ISDN upload speeds.

Below are the current upload options by provider.

Lets see what 10 years of technology improvements have done for upload offerings.


Provider........Plan..............2008 Upload Speed

AOL.............High Speed Essentials.......56 kbps

AT&T............Basic DSL..................128 kbps

Verizon.........Starter Plan...............128 kbps

BellSouth.......FastAccess DSL Lite........128 kbps

AT&T............Express DSL................128 kbps

Verizon.........Power Plan.................768 kbps

AT&T............Pro DSL....................128 kbps

Road Runner.....High Speed.................128 kbps

AOL.............High Speed.................128 kbps

Time Warner.....Cable High Speed...........128 kbps

BellSouth.......FastAccess DSL Ultra.......256 kbps

Comcast.........for Non-Comcast Custs......128 kbps

Comcast.........for Current ComcastCust....128 kbps

AT&T............Elite DSL..................128 kbps

BellSouth.......FastAccess DSL XTREME......384 kbps

Verizon.........Month to Month Plan........768 kbps

BellSouth.......FastAccess DSL XTREME......512 kbps

HughesNet.......Home Satellite Broadband...128 kbps

VerizonWireless.BroadbandAccess............800 kbps

HughesNet...... Pro Satellite Broadband....200 kbps

HughesNet.......ProPlusSatellite Broadband.200 kbps

I guess it's finally time to retire all those tired upload clichés.

What a different Broadband World than 1997.
Why I could hardly recognize it for all the upload change.

Add these entries.

Cablevision (OOL) Basic 2Mbs
Cablevision (OOL) Boost 5Mbs

The list seems to be the lowest tier for each vendor so the OOL Basic is the correct tier for the list (the BOOST is the optional higher tier).

I forgot. What percentage of the 300 million of us have access to 2MB+ upload at $25-$65/mo?

HOW many zeros after the decimal?
Big changes indeed.

crappy COAX

Jezus.. Dump the freaking coax already.. pushing data through coax is BS.. Does anybody remember ThinNET? 10-base-2?? Why did we go away from that??? hmmmm

Fiber to the prem and be done with it.. All Coax cable TV companies need to go under..
