ethernet - New construction - cat 6A. Will cat 6A patch cords work with my cat5e computer/switch ports?

    In the planning stages of a new school construction project. What is the current recommended wiring standard for this type of communication A/V heavy structure? Assuming it is Cat 6A, and all structures are wired with shielded FTP cabling, and terminated with cat6A patch panels and wall ports.

    Current switches and network cards in the computers are cat5e 10/100/1000 mbps ports. Will the existing cat5e patch cords work? If not, will cat6A patch cords plug into cat5e machine ports on one end and cat 6A wall outlets and patch panels on the other end?

    I have seen a few articles talking about cat 7 and cat 8 wiring? Should we be looking at those to future proof the network? IF so the above question would still apply.

    The signal will be fine running over cat6A or cat5e. The order of pairs and interface (RJ45 or 110 punch) are identical for both cables. The only real differences are in how the twisted pairs are arranged inside the cable for the purpose of carrying the signal. Cat5e is capable of 1Gb, but is less resistant to interference, length of run and sharp bends/damage. The signal that runs over the cable is also identical. There is no real discernible difference between cat5e and cat6A jacks and patch panels except that they MAY be made with slightly different grade materials (depends greatly on the manufacturer). Mostly it is just marketing when it comes to the structural interfaces.

    I'm looking to wire my home with CAT-X (where X is probably going to be CAT-6, unless someone can convince me differently. ;) ).

    I'm seeking advice on what equipment I'll need for the job, and any things I should watch out for.

    It's a two story half-duplex I'll be wiring, roughly about 1800 sq ft.

    Here's what I believe I need so far:

    • Bulk CAT-6 Ethernet cabling
      • CM Rated
    • Gigabit switch(es?)
    • Patch panel
    • Equipment for cutting, terminating wire, fishing through walls, etc
    • Wall outlet covers, etc.

    Questions I have:

    • Does it matter the MHz rating on the Ethernet cable? If so, why?

    • I have two gigabit switches currently, an 8-port and a 5-port. Should I buy one massive switch to cover all the connections I need, or should I just chain the two together and buy a switch for however many other connections I need?

    • Do I really need a patch panel? I understand it keeps the cables looking cleaner than coming out of a hole in the wall, but is there some other product I can use, perhaps combining a switch with a patch panel or some such?

    Ideally I'll have all this running out of a relatively small closet, so the less components (or smaller) the better.

    Any advice, links, or suggested product to use/avoid would be appreciated!

    I would personally stick with CAT5e for home wiring. CAT6 will show no improvement, and will cost you more.

    I would consolidate to one switch. Easier to manage and less points of failure.

    I would also avoid a patch panel. I think they are overkill for a home project, and just considerably add to the cost. I would just terminate with RJ45 and hook it up to the switch. I personally just got creative with a shelf and some zip ties. I mounted the shelf pretty high up in the laundry room so you can't see the cables at all.
