Sync speed difference between RJ11 cables.

(1/18) > >>

banger:
Just did a quick test between an old Billion 7800 RJ11 flat lead and a Tandy twister pair sheilded RJ11 cable.

The results

Max sync
72/17   Tandy
78/17   Billion

I have tried this before and got similar results.

My conclusion is the Billion cable is better and when I reconnected the Billion cable I gained 200k.

Make of that what you will.

NewtronStar:
Not again the problem with shielded cable it's not grounded the shielding in that cable acts like an Ariel picking up unwanted stuff from who knows where, the flat or twisted pair will do a good job as long as the cable is no longer than 2 meters

banger:
Ah, that is why. I don't think the flat cable is twisted both cables are 2m.

Ixel:
That's why I don't use shielded cable (Tandy's), unless grounded their impact (whether positive or negative) will be random.

I don't use the flat cable however, I use a 2 meter Cat 6 RJ45 to RJ11 UTP (unshielded twisted pair) cable and it works fine, it'll offer better resistance to noise for that 2 meter run compared to the cheap/bundled flat cable. You can find this type of cable on eBay already made. Besides, if I do manage to get g.fast at around 500 meters from the cabinet then maybe it'll also come in handy for that!

banger:
Thanks for the tip Ixel. I shall have a look on eBay now.
