Re: Alternative options of inbuilding wiring for MDUs or buildings
There are lots of in building solutions.

NTT created some very interesting ones as part of their buildout.  They ran fiber right to a socket on the wall.  Just like a phone jack and provided bendable fiber with an ONT they mailed to the sub for installation.

They also had an interesting way of dealing with bringing fiber through walls.  Had to do with conduit and fiber made into a coil and vacuum sucked through the conduit.

Was fascinating to watch.

Alternative options of inbuilding wiring for MDUs or buildings
As we know, technically fiber is the best option for high speed broadband service for home and office. but, in reality, home or in-building inner wiring would be a barrier to enterance of fiber.

 

Korea seems try to overcome this wiring matter by utilizing alternative wiring technologies such as G.hn G.fast, 2-pair UTP (?). Actually, I found a web site that talks about a various inbuilding wiring scheme for MDU or buildings. It seems interesting to me.

 

Now giga Internet service available from all the Korean big 3 operators

Re: How does a neigborhood ready for fiber connections?
And it's not just trivial facts that "...they have yet to hit a single unserved or underserved area.  They are being a 3rd provider in saturated markets..." One wonders where the do no evil is in that. If Google wanted to really be good guys you'd think they'd look at a few of those underserved areas.

Re: How does a neigborhood ready for fiber connections?
kjsing,

Thanks!  Broadband Access is a tough topic for several reasons:

- It involves consumers directly

- It involves municipalities directly

- Trying to build a general model is hard

To give examples:

- There is a shotgun test for street cabinets in the RBOC specs.

- I was told (by a US West employee) that the Next Level roll-out in Phoenix took 1400 building permits.

- Demographics of areas fall into categories but can you build a model that works in downtown NY and rural Nebraska.

As to Google being serious...and yet...they have yet to hit a single unserved or underserved area.  They are being a 3rd provider in saturated markets where the technology deployed to date is the most competitive in the industry.

Thanks Seven. It seems to me that one could write a book on this stuff that would make nice reading material.

Re: Google Continues Gigabit Expansion
I've heard that same thing... We (or maybe just I) want to be cynical about it and think that they're up to something, but I've heard from vendors and companies involved in the construction that they're very serious about being a broadband provider.

Google Continues Gigabit Expansion
With the massive caveat that I don't know much about the U.S. broadband access market (ha!), I met a very senior exec at a large, influential US vendor a couple of years ago, who said Google is ultra serious about the fibre-to-the-home expansion. He planned on selling them a lot of gear.

Re: How does a neigborhood ready for fiber connections?
Just for clarification, the BellSouth portion of AT&T was rolling out FTTC from the late 90s on.  

One other clarification.  The CLECs never rolled out Residential DSL in volume.  The rolled out Business DSL for the most part.  One of the reasons is that many residences in the US (about 1/3rd - maybe more now with the advent of U-verse) are behind street cabinets.  UNE-L is basically impossible behind a cabinet (thus presenting all kinds of issues for Sonic for example).  The FCC had a symposium but so little is known by most folks about street cabinets that they could not help.  What would have worked, had the CLECs survived, is Project Pronto unbundling.  But only AT&T had to do that.

To street cabinets.  They are all limited on space, power, battery and heat dissapation.  You can not be sure that you can add a DSLAM to any cabinet.  There are also wiring issues, particularly in the RBOCs where they locate the F2 crossconnect away from the cabinet.  That means that to tap into a line for DSL it has to be run back from the crossconnect and then back out unless you are on a combo card (a card with POTS + DSL + Splitter combined).  So add available pairs and distance to the list of problems.

Pronto was going to be done by unbundling ATM VCCs at the Central Office.  So a CLEC would do something more akin to UNE-P and just get an ATM stream from the ILEC (over an OC3c).  Of course, this means that the CLEC could not use different DSL technology than the ILEC was.  So, it was not useful from a competitive standpoint.

One other problem with this now that we are on IP DSLs.  ATM DSL has the one advantage that from an unbundling standpoint that each port could be on a separate IP subnet.  To do that today, we might have to have QinQ similar type uncoupling.  AT&T and Verizon have gone to Layer 3 homes, where as many of the IOCs used Layer 2 homes (so they could have their data and video in different subnets).  Ah layer upon layer of issues.

Re: How does a neigborhood ready for fiber connections?
Thanks Seven. Your explanations clarify a lot. Interesting is indeed the point you raise about Title II and the Cable companies when viewed in the context of today's debate on Title II as it relates to ISPs and the increasing shift from conventional phone services to converged data, voice and video services. Also interesting is your point about ILECs and CLECs. I remember the telecom boom of the late 90's when CLECS took the lead from ILECs in rolling out ADSL, subsequently the FCC announcing that ILECs would not be obliged to lease out their FTTC or FTTH lines to CLECs in order to give them an incentive to rollout fiber. It took nearly 15 years for ATT to invest in FFTH/FTTC.

Re: How does a neigborhood ready for fiber connections?
So for phone lines there is already a line running from the grey box at your home to a patch panel in the neighborhood, right?

---- Right

In that case who owns that line? The city, the phone company?

--- The Phone Company

If the phone company, which one in case there are two or more telecom providers operating in the same neighborhood?

--- There is only 1 ILEC in any given area and they likely built the only lines (it is possible that somebody overbuilt but it would be EXTREMELY rare).  A second phone company in the area is a CLEC and is renting lines from the ILEC under UNE-L (In my area, Sonic.net does this).  UNE-L is NOT required for FTTH or FTTC (up to 500' of copper) - the rules for this are on the FCC site.

Note, cable companies are not required to unbundle their infrastructure.  It sure would be interesting to see how Title II evolves there.
