Pre wired Dual Network boxes

Discussion in 'Home Networking' started by Peter Crosland, Jan 9, 2011.

  1. Having Googled without any success can any tell me where to find a source
    for wall mounting network boxes with two pre-wired RJ45 outlets? Of course I
    could use two modular sockets but I would prefer the former. TIA

  2. I've not heard the term "pre-wired RJ45 outlet" before. Could you point one
    of these out?

  3. What I mean is a non modular one with two RJ45 outlets that only requires
    the incoming cable to be connected to one place without the need to wire
    between the sockets. There is probably a different name for it.

  4. If you are looking to use one existing Ethernet cable to support two
    different computers then it is possible, provided the devices involved,
    router or switch, computer Ethernet ports, are designed for 10 or 100MBs
    speed. 10 to 100Mbs only utilize 4 of the 8 wires in the cat5/6 cable
    per computer leaving the other 4 wires for a second computer or even
    phone line(s).

    The newer 1000Mbs systems use all 8 wires for just one computer and as
    such can not be split without the use of a Ethernet bridge or router and
    you can not mix an old style analog phone and computer on the same cable
    with one of them.

    There used to be all in one splitters pre-wired wall plates but I seem
    to remember they cost about the same as a modern 4 port Ethernet bridge.

    Here is a link to a video showing how to use the little pre-made
    Ethernet splitters that plug into the wall jack and allow two computers
    to run on one cable, but they have to be used in pairs, one at each end
    of the cable being split.

    The above is one long URL so if it comes in two parts at your end you
    have to enter all of it into the browser to use it.

    You could be use the "splitters" to run one computer and up to two phone
    lines on the same cable provided the already mentioned speed
    restrictions are kept in mind but that would most likely require you to
    make special adapter cables for more than one phone line.

    You could use one of the above modular splitters at the switch/router
    end and hand wire a double Ethernet jack set at the end with the two
    computers if you want provided you understand which wires to route to
    each wall jack.

    Isn't it called a 2-port hub/switch?

    I don't know of anyone who makes one. I'd suggest you get a small 4-
    port switch and screw that to the wall.

    [Note: Beware of the Belkin plug-in 2-port adaptor, which they
    misleadingly call a "passive hub" -- it's not a hub at all, it's just
    two RJ-45 sockets wired to a single RJ-45 plug. It *looks* as though it
    might approximate what you're after (it's not wall-mounted but you
    could plug it into a single wall-mounted socket) but it won't do what
    you seem to want.]

    That's not a normal use of a double socket - although it can be done to
    get two 10/100mbs connections onto one cable, it won't work for
    gigabit. As it's a bit of a bodge I'd be surprised if anyone offers a
    pre-wired solution.

  7. If Peter means to use two of the four pairs on a single cable for each of two
    ethernet circuits he should try these:

    Except as he's talking about using a wall socket he'd have one of those
    dangling on a short patch cable - not exactly elegant. :)

  9. Thanks for your reply and to the others for their suggestions as well. I
    think the cheapest and most elegant solution for my requirements is to use
    two modular outlets and wire them internally.
