Who among you is still wiring your networks with Cat5e? That’s an excellent question. While I would like to think that amongst savvy readers the answer would be “nobody,” the fact that I still see Cat5e stocked at supply companies and offered in stock lists for online distributors tells me that, statistically speaking, the real answer is “some of you.”
Well, if you are, please stop.
It is now time to be wiring all of your networks, whether data or video distribution, with Cat6. And I’m going to tell you why -- bandwidth.
Cat5e allows transmission of up to 100 megahertz (MHz) with an impedance of 100 ohm. Cat6, however, allows a transmission of up to 250 MHz, and is certified for use at gigabit (1,000 megabits) speeds.
That difference didn’t matter a whole lot a year or two ago, but now it matters a lot.
The bottom line is that Cat5e and Cat6 are structurally different cables, with each suited to different tasks. While Cat5e is sufficient for distributing component video, AV pros need to move up to Cat6 in order to accommodate the necessary bandwidth and packet size to handle digital HD. Read more...
