The only ones that I saw that were braided had clear jackets. -- Best Regards: Baron.

The cables I had bought for $0.69 each from www.cableswholesale.com had an inner foil shield and a substantial outer shield of tinned copper braid. Most other cables at least appeared to have a braided shield. I don't think it would be possible to meet the USB spec of 0.6 ohms with just a foil shield. I am returning 80 pieces of the 100 I had bought that are still unopened and unused. I also contacted www.monoprice.com because they have very good prices, and some with gold plating, but my technical questions have remained unanswered even though several people have responded. I asked for a free sample (list price is only about $1), but nothing yet, although they all say they will issue a refund if not satisfied. But I'd have to take the time to place an order, pay maybe $5 S$H, then test it, and then pack it up and spend a couple dollars more to ship it back to get my $1 refund. I found www.trianglecables.com, and they say that their cables are custom made to their specs. They have some that have ferrite filters built into the cable, so I ordered an assortment of six cables with and without (6ft and 10ft, black, white, clear) for a total of about $25 including shipping. I should get the shipment in a couple days and I'll report back with findings. It seems that the USB3.0 cables have a larger type B connector so I can't use them. Paul Paul |
