VERY few 8P8C "RJ45" plugs are rated for stranded cable and they're definitely not a stock item where I shop. The pins have to be shaped differently than a solid conductor plug so as to ensure they don't push past the strands, and make good contact.
Same goes for stranded CAT5; I don't know that even exists in a thousand foot pull box. Stranded cable has less current carrying capacity than solid and is primarily for flexibility, e.g. patch cords. I can't think of an application where stranded CAT5 would be necessary as a main link.
Thanks U1 - I recommend solid cable for horizontal/structured cabling. You can purchase RJ45 mod tips that work on either or that are optimized for conductivity specifically for stranded or solid based on the design of he teeth.
Before I start my response, I laughed so hard at the thought of the bunch of beanies. But one thing I don't see mentioned, is the "twist" aspect of a twisted pair. The twists are to prevent cross talk on the wires. When splitting these wires out, it is important to punch down or crimp them as close to the twists as possible. I have seen many installs where the wire is strait for one to two inches leading up to the RJ45 connector. This generally is bad and should be avoided. A "beanies" method would be just wrong.
I've often wondered about this, so maybe someone with more knowledge can answer this for me.
My understanding was CAT cables use twisted pairs to reject EXTERNAL interference from AC electromagnetic fields and RFI, because Ethernet uses DC current which has absolutely no inductance. "Crosstalk" between pairs should theoretically not be possible, and the varying twist rates is to enable the differential signalling to do its job at the device end.
Am I out to lunch or does my thinking have some merit?
