fibre between floors

    A new building has got fibre between floors in the plans: but the data flow is fairly minor, and there are only two floors. Does the complexity of managing the fibre install outweigh the option of just running straight cat6? Enquiring minds want to know. It's only a 30-person site.

    Distance & shielding would be the two major benefits, but in this case as its such a short-run I don't see the benefit of fibre. Unless you already have equipment that uses it then its going to be a case of purchasing fibre switchs & patch-panels.... plus the conversion is going to add in extra latency... if in the case where there'll be switch/server rooms on both floors it could be a benefit (in the case of extending fibre-attached storage for example).. but again only if existing equipment uses it.

    There is no harm in running the Fibre. But the CAT should be equily as good. Is there a massive gap between the floor? i.e. basement to the 20th floor?

    Nope, no fibre-attached equipment, and a greenfield site, and it's one floor over another.

    Think I'll suggest they engineer it out.

    If you are using decent managed switches you could probably aggregate say four cat5e cables and so have a 4Gb full duplex backbone for very little cost apart from the labour of running the cables.

    Fibre will offer longer distances - N/A
    Fibre is immune to noise - N/A

    The next standard is 10Gb - but won't be there for a while and won't be cheap until mainstream.

    If you all PC's only talk to the server and not each other and the server has a 1Gb card then you don't need more than 1Gb anywhere else as that is where the bottle neck is.
