advantage of fiber over copper-based media

There is a question that states, "What is the advantage of fiber optic cable over copper-based media?" The correct answer is that it is immune to EMI. I was thinking that since it is copper based that it would not be immune to emi, but the advantage would be that it is easier to implement. If someone could clarify, it would be appreciated.

Thanks,
Natalie

    Speed
    Not susceptable to EMI

    I think you have the question slightly reversed. Let's do it like this:

    Fiber advantages:
    Immune to EMI
    Much longer range before attenuation, and potentially higher transfer speeds (depends on what speed fiber you're using of course)

    Fiber Disadvantages:
    Much more expensive
    More difficult to install

    Copper advantages:
    Cheaper than fiber
    Easy to install

    Copper disadvantages:
    Prone to EMI (especially around flourescant lighting)
    Shorter range than fiber (100m on base T)

    Edit: Noods beat me. :P

    Another for fiber, not prone to eavesdropping....
    What next?

    Thanks for the replies. I just realized I was reading too much into it. I was thinking of cddi. Thanks for the examples to deal with my brain lapse. :)

    fiber is also "media independant"
    meaning the capabilities are unlimited.
    they are limited only by what we can do with the light.
    ie how good the lasers are .... dwdm,cwdm.
    copper has phisical limitations of distance, emf and so forth.
