Talk:Twisted pair

From Wikipedia, the free encyclopedia

Regarding unshielded twisted pair

If it ain't shielded, it'll short-circuit. So someone should correct this unprecise phrase, please. thanks, --Abdull 12:08, 17 Mar 2005 (UTC)

you mean insulated. electromagnetic shielding is different. - Omegatron

"f cancelling out electromagnetic interference kno"

technically magnetic interference, right? only shielding cancels electric interference. - Omegatron 16:55, Apr 15, 2005 (UTC)
Hmm.. effect of the magnetic field from one wire on the electrons from the other thus electromagnetic?? Mozzerati 19:42, 27 September 2005 (UTC)
Well I don't think the method is efficient enough to cancel out direct magnetic interference, so the real thing it cancels out is crosstalk, which actually is EMI

Hi I translated the images from the German article into english, please check wether I got that right before introducing into the article. --Deelkar (talk) 01:13, 15 Jun 2005 (UTC)

Looks good! "Mantle" should be "sheath", though.

Changing it now. Thanks! --Deelkar (talk) 02:01, 15 Jun 2005 (UTC)

There are contradictions between the German and the English article concerning the nomenclature for STP, S/FTP and S/UTP. Especially because some manufacturers seem to call their cable STP while meaning S/UTP.--Deelkar (talk) 02:26, 15 Jun 2005 (UTC)

[edit] Merge stubs into this article

I have already gone ahead and merged the shielded twisted pair stub into this article. I would also like to do so with the unshielded twisted pair article. Before I do so, I'd like some other people's opinions. N. Harmon 01:35, 28 May 2006 (UTC)

I think the foiled twisted pair article should be merged into here also. N. Harmon 01:43, 28 May 2006 (UTC)

I also think we should consider merging several cable category articles into this one. N. Harmon 02:22, 28 May 2006 (UTC)

Oppose the merger of cable category articles, but support the merger of the twisted pair variants. The cable category articles are (from what I can tell) pretty good, this article shouldn't concern itself with them. By the way, from the history I noticed that the user Mozzerati originally seperated the sections, see what he has to say. Also, take a look at all the articles pointing here and see if it is possible to improve that. In my opinion this article is in need of some serious attention, I'll help around where I can. --Bruce 09:54, 28 May 2006 (UTC)
Two of the cable category articles are good, specifically Category 5 cable and Category 6 cable. However they do seem to repeat a lot of information that is really about twisted pair cables and not necessarily THAT category of cable. I appreciate your thoughts on this. N. Harmon 15:37, 28 May 2006 (UTC)
Oppose keep specialized info in seperate articles. Generic info might be merged into twisted pair. Bemoeial 12:48, 6 June 2006 (UTC)

"'oppose'" - There are hundreds of type of twisted pair cables, but "Category X" is not a generic term, it is a specific term for this particular cable. It deserves a place of it's own. Trane Engineer

"'oppose'" The information for Cat 6 cable was good, and should be in its own catagory. <pun> I would not look it up under twisted pair, I would search under Category X. Twisted pair is too general, like putting it all under "wire". 69.31.216.194 17:48, 6 June 2006 (UTC) Tom Moffatt

"'Oppose" It does take some knowledge of most types of media cable to differenciate twisted pair. It can't just be classified to just Cat5 cables! ~ T. Hansen, California

  • Oppose Too much info to merge, Wikipedia is not paper. Themindset 16:15, 9 June 2006 (UTC)
  • gently oppose there's a real need for a discussion of the physics, grounding characteristics etc. of the different types. I started to think about writing it, but got sidetracked. I think they are sufficiently important and different to be worthy of separate articles. On the other hand, there's nothing wrong with merging for some time and then later splitting again.

[edit] Cancelation between pairs

To me it is not obviously why two pairs in the same cable does not crosstalk a lot. It looks like they are two coils on the same transformer. I expect that they are twisted at the same rate. Appearently this is not the case and I think this article should explain why. 62.79.30.244 08:23, 12 February 2007 (UTC)
