[QUOTE="Dan Mortensen, post: 147614, member: 2826"] Re: Cable It's funny; that notion seems intuitively correct but according to Steve Lampen of Belden (see video part 1) is factually incorrect. Modern copper annealing and/or other treatment has apparently made solid Ethernet cable as durable as stranded. It would be an interesting experiment to make a couple of short cables using solid and stranded and the appropriate RJ-45's for each (I have some specifically for stranded with inserts that I bought a couple years ago, but looking again recently the options seemed fewer and the connectors stated they were for both solid and stranded) and then bending each a thousand times and see what happens. I bought stranded for the couple snakes I built because it was the only thing available from Monoprice when I needed a pile of cable, and so far so good after nearly two years of periodic use indoors and outdoors for the 150', indoors only for the 250'. There is an issue in that the measured standard ("meeting the spec") for stranded is different than for solid so stranded will fail its test much more often than solid will. HOWEVER, stranded is intended for patch cords ("patch" in their terminology) connecting to long runs of solid ("channel" in the terminology) which are the main runs through conduit or walls or whatever to connect gear together. In other words, the "Patch" standard assumes whatever existing deficiencies are in the channel you are connecting to (which had to meet a lower spec already), so the patch cord has to be damn near perfect to connect to the imperfect channel. In my portable console use, I am not connecting to any built in channel but my stranded cable is actually the channel (my snake, in other words) so that it really only needs to meet the "channel" spec. This is mentioned in the second video connected to the workshop that I posted. In that video (with Kurt), I am not quite clear on the concept yet and ask several questions that are not quite worded correctly and get answers that are just off the mark until we finally stumble upon the concept that it's possible to have a stranded cable that is used as a channel and therefore only needs to meet the channel spec. I think that's maybe why people denigrate stranded cable, because it so often fails the certification test, which, again, is vastly more strict than for solid cable used as a channel. My posts are long enough itt without spontaneously discussing what that certification test means and how to know if your stuff will pass it, absent someone saying they want to know. Steve raised an issue in one of the videos about the stranded cable moving around within the teeth of the RJ-45 connector and failing that way, and I'll reserve judgement on its accuracy. He certainly has more experience than I do, so there's that, but there are electrical connections made to stranded cable all the time without problems, so there's that, too. [/QUOTE]
