Talk:Fiber to the x

From Wikipedia, the free encyclopedia

I suggest that FTTx shall be merged into this article.--Willpo 07:10, 4 March 2006 (UTC)

I've merged it. ~MDD4696 06:28, 12 March 2006 (UTC)

I have restructured the article moving outside of it parts that were already explained in other articles cgbraschi 26 February 2007

[edit] Fibre to the cabinet

I am moving fibre to the cabinet to the fibre to the node line to align with the article it refers to (is redirected to fibre to the node) --Cgbraschi 15:31, 27 March 2007 (UTC)

[edit] Title change

I propose changing the title of this article from "FTTX" to "Fiber to the x" in order to make it more consistent with Wikipedia's naming conventions on acronyms in titles. Such a change could be done using Wikipedia's article moving feature, which would allow two good things:

1. the current edit history would be preserved under the new name
2. anyone searching for "FTTX" would be automatically redirected to "Fiber to the x"

No one has written any comments and it has been over a week, so I have proceeded with the move. (We can use "move" to go back to the acronym title if we really need to.) If anyone objects to the spelled-out name, please discuss here before taking action. Riick 06:03, 12 March 2007 (UTC)

[edit] Restructuring proposal

In current usage, the difference between FTTC and FTTN is very subtle, as both usually have in the end a similar architecture, the only difference being if the Curb is nearer than the node. Given that the main tecnology behind both of them (VDSL2) is not able to reach more than 700m, any deployment farther away from the home is not practical, and the difference between the two disappears. Look this article or if you don't want to register in google for "communications breakdown telecom magazine" and look at the cache of the first article.

I propose unifying both terms in the same line, and then consequently merging the FTTC and FTTN articles into one, leaving only three concepts inside FTTx: FTTH, FTTB and FTTN. This is the current use in the industry. --Cgbraschi 15:16, 23 March 2007 (UTC)

I was aware that there was an overlap between FTTN and FTTC, but not that FTTC was neccessarily a subset of FTTN. I thought that in cases where the switching equipment served just 2 or 3 houses it was not considered FTTN, and therefore should not be included in an FTTN article. We'll need to find some supporting references for this; please give me a week to investigate. In the meantime, if anyone knows of any evidence that either supports or denies the idea that FTTC is a type of FTTN, please post it here. (If we can establish this, then such a merge would be consistent with Wikipedia's discussion of merging, which states, "If a page is very short and cannot or should not be expanded terribly much, it often makes sense to merge it with a page on a broader topic.") I have also posted tags on fiber to the node and fiber to the curb which link to this discussion. Riick 22:09, 24 March 2007 (UTC)

There is little business case into using an equipment to serve just 2 or 3 houses (or even 10), usually the remaining copper loop is so small is worthwhile putting fibre instead. And no deployments. So even if it is a theoretical possibility, it has little deployment in practice, and very little architectural difference between FTTN and FTTC. I'd like to point out that FTTx is about architectures, and then there are different technologies. —The preceding unsigned comment was added by Cgbraschi (talk • contribs) 09:37, 26 March 2007 (UTC).

I agree that FTTN and FTTC are nearly identical architectures. What I am not yet conviced of is the idea that current industry usage has FTTN referring to both. So I searched for examples where the term "FTTN" is used to describe FTTC-style architectures.

I did find a few articles where it might be possible to argue (based on the context) that FTTN is being used to include FTTC. Unfortunately, these articles do not specifically clarify what they mean by "FTTN", so it is hard to tell. One article (see page "106") does specifically state that FTTC is a type of FTTN. (It further states that FTTP is a type of FTTN- for them FTTP means FTTB.) With the exception of that one article, any articles which specifically describe the situation where the fiber comes close to the customer (ie less than 1000 ft) consistently draw a distinction between FTTC and FTTN. (Some use the term FTTCab instead of FTTN). Some of these articles acknowledge that there are borderline situations (where the ONT is 1000 feet from the farthest customer) in which either term could be used. But none give the impression that the term FTTN can be used in place of FTTC aside from these borderline situations.

So the question remains- Would most experts agree that the term "FTTN" includes those architectures where all customers are within less than 1000 feet (300 meters) of the fiber? If the answer is yes, then it would make sense to merge FTTC into FTTN. However, most of what I have seen so far indicates the answer is generally no. Therefore I don't yet agree with merging FTTC into FTTN.

This said, I do think it might be appropriate to include a paragraph saying that although the meaning of FTTN is generally distinct from FTTC, some people use it more broadly so that FTTN = FTTCab + FTTC + FTTB. Riick 00:25, 28 March 2007 (UTC)
