UTP vs FTP Ethernet Cable for 100m Network Runs: Speed and Interference Differences

Question

Which cable is better to use to build a network, UTP or FTP? Are the differences in transfer speed big? I mean mainly long distance transfer, i.e. 100m.

There is no difference in speed. A poorly done FTP installation causes more problems than good. The need to use a shielded cable is only in an environment with strong interference, e.g. factory halls.

I do not agree with the previous speaker. I used to have a 180 m utp line. It was maybe a month and then it died. I exchanged it to ftp and surprisingly it became stable at 100 (utp only at 10 and it fell). In addition, when it comes to hangings, utp after the first lightning bolt will burn the network card or switch. Ftp I connect the screen to ground on one side and after the problem.
From my experience on long stretches, you can see a clear advantage on ftp. In short sections it is irrelevant.

and what utp has a screen for :?: to ground it on one side only :!: in the industry you give utp or anything cat 6 in gel and patchpanel separate departure to 0 (ground)

mbo · Answer

UTP has no screen ... FTP, SFTP, etc. have it. The gelled cable is for other purposes - outdoor use and water resistance.

Hello, so how will I build a network in a block (distance around 100 meters), it does not matter whether it will be a shielded or normal twisted pair?

Just write how the shielded and unshielded twisted pair works for a longer distance, or there is no difference if it is to go basement

?

Is it supposed to be a 3 or 6 meter link or will it hold the shielded more stable over a long distance, max 100m?

Should I copy my post ?? According to the utp standard, it has 90 meters by 100 to 105 meters for 10. Unfortunately, recently there is a lot of cables with a smaller cross-section (the price of copper) or even copper-plated steel. If you want to be sure, ftp will recommend it. For utp it is roulette above 100. The problem may be with switches because from what you write, 10 is enough. But where to buy one ?? /

I think that for such distances it is better to give the shielded one, but if it wasn't, it is simply better in all respects.

mbo · Answer

This is only possible if the shield is properly grounded on one side. If not, it may perform worse than for UTP. As for speed and distance, the standard specifies operation up to 100m and 100Mb / s, regardless of the type of copper cable used. At greater distances, it can and usually does - but no one can guarantee that.

and I will tell you that I have not seen anyone in the block put FTP or STP yet. If the distance is up to 100m, then UTP will suffice greetings

mapek_sz · Answer

By the way, if there is no fear of betting about estimate and atmospheric discharges utp for sure at 100m below about goes (provided it's not some copper-plated shit). If you buy Madex, don't worry, but don't hang it outside the building, just inside. Externally only ftp grounded on one side.
