RJ11 > RJ11 Cable... Is Long Bad?

Hi. I'm looking for a 10metre plus RJ11 - RJ11 cable. I can only find 10m max but would that be bad or am I better off buying an extension.

Thing is I heard extensions can cause noise and disruption but I need for it to go from my room upstairs to the socket downstairs...

What shall I do?

Thank you in advance.

EDIT: One more thing, can I use any other type of cable instead such as CAT5 or something? It's basically going from the back of my Router to the ADSL filter to connect to the net. And do those "High Quality" cables actually live upto its name?

Long is bad, but in the scheme of things 10m is nothing compared to the length of your whole phoneline..

Having said that - use a Cat5 cable, that way it's twisted pair which will help reduce noise input, the same as your phoneline back to the exchange

10m should be fine, unless you run it near to an interference source (mains etc)

If you can get a screened cable it might be better.

Well hope mine can survive hehe. It isn't running next to anything main apart from going around are fuse box but thats behind a wall anyway, it's just running along the other side of the wall if you know what I mean.

Hey again aaronjb I couldn't find any CAT5 RJ11 male - RJ11 male cable =/

I am willing to pay abit more to get a gooden. Any links at all?

Thanks alot by the way, do appreciate the help Btw my Zen line is running smooth now. Just need to get the PC up to my room again =/

EDIT: What about all this CAT5e or CAT6, would they do the job?

Actually yeah - CAT5/5e/6 will all have RJ45 ends (sorry, blonde moment on my part!)..

You could always make your own extension up - does your master socket have a removable faceplate (NTE style)? If so you could run Cat5 cable from the back of that using a twisted pair in the cable, and put a proper socket in upstairs..

Bit more work but much neater

Cat5 cable itself (sans any ends) is cheap enough usually

(Incidentally - 5, 5e and 6 are all different specifications of the same basic cable type, it's all 8 core, four pair cable - however it's stable to different frequencies (IIRC 100MHz for 5, 350MHz for 5e and I forget for 6) to cope with different data transfer speeds)

I've seen 15m high-performance RJ11 leads advertised. Look at what Belkin sell. I've bought and used 3m, 5m, and 9m versions of Belkin Cat5-quality RJ11 leads to good effect.

There's no real performance limit imposed by long RJ11 leads. After all, your line back to the exchange is infinitely longer by comparison. Just regard the RJ11 lead as a tiny add-on at your end. Keeping the lead away from sources of interference is sensible but, again, should be no more of a problem than the rest of the line inside your house.

So-called 'screened' RJ11 leads are fairly useless, as the screen (braid) isn't connected to any pin on either RJ11 plug and so ultimately does not connect to any earthed part of the system. The leads, eg. Belkin, described as high-quality, though are arguably worth using, as the pair-twisting is somewhat better than you'll find with standard BT cable and so is more akin to Cat5 and may reject noise and crosstalk a little better.

You'll find screened RJ11 - RJ11s under part nos. such as F3L900ea15ICE-S at belkin.com and belkin.co.uk. You'll find a bunch of others there, screened and unscreened with similar part nos. Or search at Belkin for "hi-speed Internet modem cable RJ11/RJ11, Pro series". You can buy them from EBuyer.com.

Hehe no probs but nice one on the definitions, good to know what those cables are

Unfortunately I don't even have that hidden socket in my master. I've got the much older version which is pretty annoying. Had a moment when on the phone with Zen when it wasn't there heh. BT charging

Ebuyer have some Belkin cables - I can't tell from the pictures if they are twisted pair or not (if they're round cable rather than flat then it's likely):

http://www.ebuyer.com/UK/product/57737 < 30m
http://www.ebuyer.com/UK/product/57738 < 15.2 (product says 14.2, reviews say 15.2 )

For

Oh man 30m lol. That 15 is dead cheap tho! I'll put that down in my notepad. Gonna order it tomorrow. Got this and the other Belkin so far. Might give the extra few just to get that thicker wiring tho.

Just to go offtopic, i've added the log stuff from my USB Modem & Router now aaron. Here it is: http://bbs.adslguide.org.uk/showthreaded.php?Cat=&Board=zen&Number=2722764&page=0&view=expanded&sb=5&o=

Does it look right?
