who can settle this argument

  1. A friend is doing his own network wiring. He told me what he did and I
    have serious doubts as to whether it will work at all. This is what
    he's done: he ran an underground shielded cable between metal junction
    boxes mounted on the outside of two buildings. The shield is grounded
    at one end, not connected to anything just wrapped and taped at the
    other, (this was my suggestion). So far everything sounds OK. now
    here's the interesting part. He's apparently taken a twenty foot
    network cable with RJ45's on either end, chopped it in half, and wire
    nutted this to the underground color for color at each end. He plans
    to connect this between the new computer which he hasn't received yet
    and the network. I told him that he should have used a termination
    block and offered that worst case this arrangement won't work at all.
    Best case he'll suffer a significant loss of speed. He doesn't believe
    that there will be any problem with this at all though, and if it is
    it would be minor. So who's right? Can this type of cob job work, and
    if so would performance be significantly compromised, and how much?
    Thanks, Lenny
     
  2. This is probably OK, if by "network" he's shooting for connecting two 9600
    baud lease line modems together.
     
  3. Assuming this is an Ethernet * connection...

    Ethernet cables (even Cat6) aren't that expensive. Why does he need to make
    up his own cable?

    This seems to be another example of a complex "solution" to a non-existant
    problem.
     
  4. There was actually a device called "the moving cable" at a 1990s ISP I
    worked at that had a normal power plug connected to a male IEC connector.
    It had the obligatory electrical tape "lump" of a splice as you'd expect
    to see in something like that.

    The end was shrouded so no pins were completely exposed, but the idea was
    you could move computers between racks, live by supplying power into the
    monitor power out socket that old power supplies had while unplugging the
    normal power connector.

    I never got to witness it's use, but am still surprised everybody that did
    always fed power it power from the correct phase.
