I’ve talked bit about the problems of using Category 6 copper cabling in the data centre. The sheer size and weight of the cable is a serious problem. Here are some photos showing the comparison of Category 5 and Category 6 cable bundles.
This is only partially true and the user is mostly correct. The author is mostly wrong. When you bend a Cat6 cable, there is a high percentage (>70%?) chance of the damage to the internal copper core.
