    Yup 90 MTRS anything more you have to use repeaters etc but you will be fine. Just watch that you dont run it Parallel to mains cables!

    if you need to cross it over a power line, do it perpendicular rather than diagonally or in line.

    You are allowed 10m of patch cable too.

    Though IIRC you shouldn't use more than 20m of patch cable even if the backbone is shorter.

    Can't remember if CAT6 allows longer lengths, it does allow more connectors en route
