      I recently purchased a used 10/100 Cisco catalyst switch and figured it was time to upgrade to cat 6a from my old cat 5e cables.

      I decided to make my own cables and bought a spool of this superior essex 6A CMP cable.
      This upgrade made no difference at all and these cables aren't flexible at all!!!

      Hopefully someone doesn't make the same mistake I did.

        of course it won't make a difference.

        cat5e = 1gbit @ +-90meters
        cat6 = 1gbit @ +-90meters or 10gbit @+-30meters
        cat6a = 10gbit @+-90meters

        you say you run a 10/100 switch … makes no difference with those speeds.

        and no, those cables are not flexible at all, because you didn't buy patch-wire ;  you bought installation wire that should be terminated on a keystone/wallsocket/....

          Wow!!! thank you so much!  I was unaware of there being solid or stranded wire option!  My cable lengths are nowhere near that! My longest is 50ft.

            There is no reason to use anything above Cat5e for 10/100 or even gig-e.

              stranded wire is more expensive and has higher attenuation then solid wire. stranded wire should be used between wallsocket<->device & patch-panel<->switch.

                +1, not to mention people tend to bandly crimp those cables due to using unsuitable tools/RJ45 connectors/…

                  yes rj45 connectors for cat6a do exists, but they are basically keystones with a male-output
                  stuff like this:

                    I actually purchased the 6A connectors and the 6A tool to crimp from from platinum tools.

                    There was never any mention of needing solid vs stranded cable and I was unaware that it was an option.

                      In general RJ45 connectors (plugs) are designed for the 8 metal connector bits to crimp into a stranded cable. If you use solid-core "building cable" then the metal prong, that would normally press itself in between the strands of the stranded cable, will have to slip to one side or other of the solid conductor - making for dodgy connections.
                      Normally the solid-core cable is terminated at the back of sockets into a punch-down point that grabs the cable from both sides.
                      I know that for Cat5 it is possible to buy an RJ45 connector designed for crimping to solid-core "building" cable - they are a different part number… I have no idea if such a thing is sold and rated for Cat6a...

                      As the Greek philosopher Isosceles used to say, "There are 3 sides to every triangle."

                        There certainly are. In fact, there are hybrids where they use 3 teeth/ prongs so you can use both stranded or solid core cables. 1 tooth pierces directly straight down for stranded and 2 more pierce to straddle solid core conductors.

                          If you are reading this thread there are chances you might not realize that CATegory cables are interconnects and not 'bus' traces…

                          I have a friend who just built a house in the North Woods, away from all civilization, and I kept insisting she included in the wiring plan a CAT5e drop alongside every AC outlet. Of course this sounds money spent foolishly - but is is not so. The extra conduits and the actual CAT cable cost very little extra when it was laid and routed the right time in the construction process.

                          A dedicated conduit for data what is important, not the CAT rating
                          The option to turn wireless OFF, in case WiFi is interfering with whatever
                          So on... Your list of benefits or lack of them may, and will differ

                          As the matter of fact, psSense is going to be sitting right at the junctions. Without the copper-wiring all throughout the house there could be no REAL DMZ
                          Without becoming more paranoid about data security in a private home located 1000 miles from NYC in any direction...

                          CATegory is for packaging, not for rating

                            Just went through this with a co worker. Had him talked into running drops in every room plus a couple dedicated lines in the ceiling for AP's to future proof his new build. He built a $350K+ home and ended up running 5 total runs of CAT5, none for AP's, and is now adding 5 and 8 port switches at every termination point to get everything connected.  ::)

                              Unfortunately this is not limited to residential (although it's typically worse there) builds.  Most new commercial builds I see, "underplan" their wired data requirements (cabling costs real money right?).  I typically add 30% extra to the total number of drops required for a build plan (placed as strategically as possible based on the plan).  My experience has been most sites find they have used up the extra I build in with 18mos of going "live".

                              Always an argument to get the costs included in the initial build, but never a complaint when they can simply plug in a device rather than pull new cable (at twice the cost of planning ahead).
