100Mbps Cable Broadband
While we wait for DOCSIS 3.0 upgrades...

Earlier DOCSIS cable networks can only support transmissions within a single downstream 6 MHz radio frequency (RF) channel, limiting maximum throughput to around 40Mbps (shared). DOCSIS 3.0 upgrades will allow tuning into multiple 6 MHz channels through channel bonding technology, offering shared downstream data rates of 160 Mbps or higher and upstream data rates of 120 Mbps or higher (per channel).

Channel bonding combines multiple quadrature amplitude modulation (QAM) channels to ultimately offer cable broadband customers faster speeds. While DOCSIS 3.0 may not be here yet, vendors are releasing pre-cert hardware that takes advantage of these advancements. We've been seeing a growing number of pre-cert 50-100Mbps cable solutions popping up in markets such as the UK and South Korea.

ARRIS, Motorola and Cisco are all pitching such pre-standard products that will allow cable providers to compete with FTTH deployments until DOCSIS 3.0 takes off (firmware upgradeable, of course). Canadian cable provider Videotron announced last February that the company would be offering 100Mbps cable broadband service using Cisco's pre-DOCSIS 3.0 wideband solution.

Most operators are still in the testing mode, with upstream channel bonding being the latest advancement. As of today, Singapore has the only nationwide deployment of pre-cert 100Mbps DOCSIS 3.0 cable service we're aware of (via Starhub). To get those speeds, users need to purchase a $525 modem and shell out $121.80 per month.

Re: Excellent!

I would max out my 15Mbps connection when I download large files.

I downgraded to the 6Mbps package and believe it or not, I knew when the downgrade went into effect two days later. I could tell that my browsing was a tad slower.

It's not all about "the internet"....

So, if you want to know what servers can keep up with this, in the case of Comcast, it's going to be their IPTV servers, interactive services, and other internal services. Many people forget that Comcast is still a television provider first, and internet second.

I've said this for months now.. DS3.0 is not all about putting out 100mb to the home for surfing the internet. (All your P2P people need to wipe the saliva from your mouths... now) It is a way for cable to break out of the fixed frequency spectrum limitations they have now in order to deliver more services like HD channels, more video programming, and yes, some more speed, but it's not going to be 100MB up and down for surfing... forget that idea right now.

I know many people are going to come back bitching, pissing and moaning that "this is a reason for net neutrality" and every other statement, but just because it's packet data doesn't mean it has to go beyond the head end... keep that in mind before all the mud slinging and insults.

Right now I'm throttling my use down to about 1MBytes/s=8Mbits/s outbound to be nice to others in the local network. If I opened it up, it'd go to 3.7MBytes/s=30Mbits/s quickly (settling at about 3.4MBytes/s -- I tried it for a minute), and if the local network allowed me, it'd be at more like 50MBytes/second right now.

But those are at current uses. Future uses (what we should be planning for installation today) would be much more.

Hah! They are nowhere near the max of their bandwidth abilities (just sort of at the bottom right now), but they could impose all sorts of rediculous impediments to Internet use that would really curtail its usefulness, or they could offer a great set of products. Who knows.

my feeling is if France and Japan can do it, why can't the U.S. have affordable ($40 for bb, TV, phone), fast (50-100Mbps) broadband?

Because we are in the U.S. we should be paying high prices for less service?

Wouldn't bother me in the least..

I shelled out FAR more than that just for 384/128 DSL service from PacBell back in 1997.

Currently:

8.0/786 Comcast - $52.00 mo (owned modem)
1.5/896 Qwest - $65.00 mo (owned modem)

$117.00 per month

so, for $4 more, I'd be happy to shell out the money.

The answer is not easy and is not all about the "speed" quoted by marketing or the technology used (fiber vs. cable). The speed marketed refers to the last mile only and does not take into account

• how fast your PC will go (processor, NIC, disk speed, etc)
• the oversubscription of the Telco CO or Cable CMTS
• the speed and congestion of ISP traffic exchange points
• the speed of the content

The real answer is, both will be very fast no matter what they hype or FUD is. 8M Powerboost will have a similar end user experience as 20M fiber for 98% of all users.

A more direct answer to your question:

No. FIOS technology is capable of more bandwidth than DOCSIS3:

DOCSIS3: 160.00 Mbit/s
FIOS BPON: 622.08 Mbit/s (what they started out installing)
FIOS GPON: 2.4 Gbit/s (what they are installing now)

The question is not the total bandwidth but how much is allocated to the user. If you go to DOCSIS with 20 users sharing that 160 Mb/s, that is only 8Mb/s PER USER not the claimed 160 Mb/s. Also, you have to remember that all DOCSIS 3.0 does is allow the user to be using more than one channel at the same time instead of being restricted to one channel. It thus only reallocates the bandwidth (channels) on that node leg in a different way. You still must split the nodes as at present since there is a fixed number of channels to use in each node segment.

This same "how to cut up the pie" requirement also applies to the FIOS Bandwidth (you need more pies to give larger pieces or you have less people getting pie slices if you keep the number of pies constant).

This is a little like comparing apples to oranges.

2.4Gbit/sec is over the entire FIOS GPON and, by default, shared by all subscribers in a fiber serving group.

DOCSIS3.0 delivers 160M using only 4 of say 125 6Mhz channels. This could be shared, dedicated or muxed to even higher speeds depending on the need. The other channels are used for analog or digital TV, HD, VOD, voice services, etc. These allocations can also be shifted around.

Either way, both deliver the needed speeds for todays user experience and each will have technology increases over the next few years.

The major REAL business difference is FIOS is new and EXTREMELY expensive to install. Verizon is going to require MANY years to recover this investment and during that time technology will become cheaper after Verizon spends all the up front $$.

Re: Cablevision boost

So wrong , quoting the provider of some of the equipment they are using for FIOS.

"Based on these trends and predictions, APON/BPON will no longer have the throughput to support the average home in 3 years, while GPON will have the throughput to support those same homes for almost 10 years. Plus, if these predictions are off, GPON can use CWDM technology to provide up to 4 times the current 2.3Gbps of raw bandwidth using the same fiber infrastructure." (Firmware upgrade needed)

This is per group of users. IE groups of 32 on the same "Shade". Verizon uses the same frequency but dedicates it to a different shade at the junction, where it is muxed into or out of the data stream and sent to it's destination.

"Based on these trends and predictions, BPON barely has enough throughput today. GPON will be able to provide the bandwidth for over 3 years, at which time; the provider will have to use multiple virtual GPONs over the same physical PON to support the same MDU Today 3 Years 6 Years 10 Years
Number of MDU 16 16 16 16
Appartments in each MDU 12 12 12 12
BW per appartment [Mbps] 3 12 27.5 37.5
Total BW [Mbps] 576 1536 5280 7200

10 /MDU customer base. This option is not currently available to BPON users. This is accomplished by using CWDM to supply 6 wavelengths for 3 different GPON networks. While this will require some equipment changes, the physical plant will be able to support the data needs for over 10 years. If these predictions are off, GPON can use CWDM technology to provide up to 4 times the current 2.3Gbps of raw bandwidth using the same fiber infrastructure."

Not bad.

"With CWDM technology, a single fiber plant can support up to 128 ONTs and up to 9.2 Gbps of raw data per shade. This is accomplished by using passive filters rather than passive splitters. Passive filters have a much smaller optical loss than passive splitters, so the overall link
budget can handle more optical splits with the same link budget."

Well every cable company that offers cablemodem service has fibre in their setups but the way HFC works its limited bandwidth per node.
Verizon has a max of 32 subs on a 622/155 node, Cable on the other hand has hundreds of subs on a 38/10 node.
Don't the current modems have a 100mbit WAN port.

Re: nope.

I know how that cable companies have HFC networks which is fiber farther into the customer more than what the bells have---even VZ since they're just now offering FTTH and in limited areas.

I'm not sure if the current modems have a 100mbit WAN port but i think they do.

nobody gonna pile-on right away..

Any cable company who is STILL using docsis 1.1 is TOO DAMN CHEAP to upgrade to docsis 3.0 right away. This is especially true for places where THERE IS NO REAL COMPETITION. AT&T-- no real competition, QWEST-- no real competition. The teeny tiny FTTP deployments outside of Verizon territory (some municipal deployments, some AT&T, QWEST micro deployment towns) but that's about it.. absolutely NO incentive to jump on that bandwagon until the likes of Time Warner & Cablevision jump on the docsis 3.0 hardware with rapid deployment, so that they bring costs of the hardware down.

Companies are also very stingy to bring higher bandwidth to residential customers for fear they'd actually USE it for purposes that would detract from company profits (3rd party services & p2p applications).

Switching to cable..

Some of my friends are using the 100mbps cable connection from Starhub, and feedback it's quite fantastic for local content. I recently subscribed to a 6mbps/256kbps Cable service, will should be up in 2 weeks time.

Oh yeah the pricing stated in the article is in Singapore Dollars.
