Safe to use a 10m DSL cable? (Master socket to modem)


[link to this post]
 
Hi, I was wondering whether there would be any significant difference using a 10m RJ11 to RJ45 cable to connect my modem/router to the master socket? This is the cable I'm using. https://www.amazon.co.uk/LINDY-RJ-11-RJ-45-Modem-Cab...

Many thanks.

Adsl2+ or VBSL2?

It could make a noticeable difference on VDSL2 (FTTC). A small difference on ADSL2+. Mainly dependent on cable distance from the exchange for ADSL, and from the fibre cabinet via the PCP for FTTC.

Sorry, It's VDSL2.

Looks like a flat cable? If so, I would certainly be reluctant to use a length of 10m flat cable.

I have the master socket nowhere near where I wanted the router, so I put the Modem near the master socket and then use a long CAT5 to the Router

Not a great idea, but if you must use a decent cable e.g.

Using a decent twisted pair cable is essential when te distance from socket to modem is more than a few centimetres, I would not be certain about the one you have liked to however, the one ukhardy07 links to is fine being made from 2 pair Cat5e.

What you do need to be aware of is the routing you chose. What will it run past? power supplies, TVs, fridges/freezers, chargers, central heating, consumer units or large amounts of mains wiring ...

I would use a Cat5e but the cable is RJ11- RJ45 as opposed to RJ45-RJ45 because for some reason the DSL port on the modem is RJ45. The cable that came with the modem is 4m and I might be able to do it with a 5m cable so maybe that's my best option..?

Is there a way to work out if the cable I linked is twisted pair? (I'll probably buy the 5m version)

There is two possibilities, the first is that in fact it's a WAN port and not a DSL port and the second is that it's a combined DSL and WAN port and that's why it's an RJ45.

Sorry to hijack this thread,

Would this 5 m shielded one be any good (for me) ?

https://www.tlc-direct.co.uk/Products/CX701HS.html

It's to replace a standard one, that came with the router (from Now TV).

I would like it to be a bit longer than the current 3 m one, and thicker.

Thanks in advance.

CJT.

It is the cable type that matters - Cat5e and you could have whatever connectors you want on the end. RJ11, RJ12, RJ45, BT601, jack plug ...

Don't take the risk with the one you link to but the other as linked to by ukhardy07 - here will be ideal.

It may be RJ11 at both end but the critical part is Cat5e (and only the thinner 2 pair which is good). RJ11 will fit into an RJ45 - they were designed to do that, or contact the seller and ask if he will make an RJ11 to RJ45 one for you and at your required length.. All his cables are hand made in the UK

He also, for example does RJ11 to RJ45 in Cat6 LINK

And this is the one you may need:

https://www.ebay.co.uk/itm/BT-Infinity-5M-Cat-5e-Mod... And at £9.99 cheaper than the link you have.

Or, if the master has unfiltered connections on the back plate then connect a standard cat5e directly to those and at the other end fit an RJ45 socket and use a short cat5e drop lead to connect from that to the router. Saves having to worry about the plugs on either end of the extension at all.

I agree, a much better way, however, not always the cheapest and making the connections puts some people off.

And my earlier point about avoiding potential noise sources is still relevant.

It just says DSL underneath it; it's a Frtiz!box 3490.

Don't DSL and WAN ports serve the same role though? (provide connection to the internet through your DSL, rather than to your local area network [LAN] )

My previous modems/router just used an RJ11-RJ11.

Thanks.

What do you mean by "only the thinner 2 pair which is good" ?

Cat5e cable can be either 4-pair or 2-pair. ADSL and VDSL only require a single pair and an RJ11 normally has just 4 pins populated wit two empty. 2-pair is thinner and easier to use than 4-pair.

If you try to terminate 4 pair in n RJ11 there will be two pairs that are just cut and bare at the end - they look untidy and are a waste as well as not being enough room for them to be inside the connector and gripped.

I make my own - and always use 2-pair Cat5e.

If you have a separate modem which interfaces to the VDSL then the output of that will go to the WAN port on the router - it is Ethernet not VDSL level signals.
