    Wiring up ethernet socket

    by garry89 ·

    Hi I’m planning to run cat6 armour cable from my house to my shed and I’ve got 2 wall sockets, I believe they can be wired up A or B wiring but I don’t know what wiring plan A or B my patch cables will be, does this matter? Or is there a way of checking the patch cable so you can find out which wiring patter has been use. Many thanks

      For me.

      I have always used the usual wiring pairs which is readily available on the web. There are two color schemes I encounter and both used the same pair numbers with a variance on colors so electrically the same.

      I’ve seen techs get uppity about the colors so for me as long as the pairs and numbers are maintained I don’t give a hoot on the color scheme as long as it works.

      Another tip about calls to work in wall wiring is to always carry a 100 foot factory made Ethernet with you to be able to test if the connection should have worked. Without that you could lose hours futzing around with a bad cable run such as one with a broken wire or where a nail or staple was put through the cable.

      As stated previously you can use either

      But just make sure that both ends are the same if you use A at one end you need to use it at the other end.

      The other thing you have to look out for is the length of the cable run between the house and shed and this is the entire cable run not just the length of cable between the sockets it is the length of cable between the Hub/whatever one end and the computer at the other or whatever it is in the shed as I’m presuming that the primary Internet ingress is the house and not the shed.

      Anything over 185 Feet from memory is pushing the upper limits of any form of CAT Cabling so make sure you are not approaching that length and make sure you have Gold Connectors on both the Sockets and Plugs of the cables so there is no possibility of corrosion forming and making a High Impedance Joint which will stop any communication over the Cable.

      Just to add the very basic also no joins in the cable between the house and shed that run needs to be a straight uninterrupted cable and if underground in conduit that is glued at the joins so nothing gets into it. The number of times I’ve seen joiners in exposed cabling that used to work Once Upon a Time and no longer works is unbelievable you can not have any joins in CAT Cables when they are exposed to the elements.

        Thanks so much, the distance is less than 50ft all in, I’ll try keep the cable as straight as possible with no hard bends.
        I’ve bought 23m of armour cat 6 which will be plenty.
        I know to make sure biut ends are wired ‘A’ but how do i know any patch cables I use are also ‘A’? If they are ‘B’ will it matter? As I’ll be buying them so no idea the wiring ‘A or B’

          Doesn’t matter as they will be the same both ends

          All the wiring shows is Colour Codes but electrically the electrons do not care if they are in any colour so they just flow. The real problem with the A,B Wiring is that one end gets wired up A and the other end ends up as B which just means that each wire goes to a different position on the socket all you really need is the same wire going to the same junction so they do not crossover or anything like that. If you stick a Crossover CAT Cable in one end between the socket and whatever it will behave as a Crossover Cable for the entire length but if you use a Cross Over Cable both ends the entire cable run is a straight CAT Cable.

          Also if you are burring this underground make it at least 18 inches deep so the likelihood of a shovel or some other garden implement cutting the cable is unlikely unless you are digging a hole it is something that happens on a regular basis and why I like Conduit, as when most people hit the conduit they stop and look to see what is happening but if they hit CAT Cable even Armoured CAT Cable they have done the damage before they realise.

          Happens all of the time.
