 Practice test help
Hello,
I have a couple of questions that I would like some help with, these are on a practice test and I can't find them.
How many wires are there in a 25 pair cable?

I think this is 50 wires in a 25 pair cable.

What connector is used when terminating a category 6 cable?

EIA/TIA 568A is a recognized wiring standard?
I think this one is yes.

Any help would be greatly appreciated.
Thanks,
Mike

Dear Mike,

We have a policy here of not answering student's question to encourage you to find an answer on your own which will make you retain it better.
However, this question has been in our queue for so long that I presume you have already taken and, of course, passed the test. So, here are some answers for other people's future reference:

  • How many wires are there in a 25 pair cable?
  • - 50

  • What connector is used when terminating a category 6 cable?
  • - Oh, a tricky one! I think they wanted you to answer RJ45 but it would be a very common misnomer. It is just 8P8C (8 pins , 8 conductors) connector. RJ45 stands for a particular pin layout, and it's not even a complete name. Besides, you can also terminate CAT6 cable with a 110-type and S210 connectors. But you really have to look into your textbook to know which one did they want you to give as a correct answer.

  • EIA/TIA 568A is a recognized wiring standard?
  • - another tricky one? The current edition is TIA/EIA - 568B with "C" just around the corner but your textbook may be just only enough to not make a distinction.

    Sincerely,
    Dmitri Abaimov, RCDD
