Category 5e cable is nominally rated for data transfer at 100 MHz, but actually can handle speeds up to 350 MHz through four pairs of twisted wires which can carry four different signals at a time. It is also backward-compatible, meaning it can replace older Cat5 cable being used in an installation without causing problems.
As Cat5 cabling became commonplace, the need for one major improvement became apparent: greater protection against interference. That’s the primary difference between Cat5 and newer Cat5e (the “e” stands for “enhanced”) cable; it greatly reduces the amount of crosstalk interference between the different signals carried on the connectors. It also helps reduce electromagnetic interference and other signal noise, all of which can lead to signal degradation. Cat5 cable is rarely used these days for new installations, having been supplanted by Cat5e.
At CableWholesale, we take our bulk network cable business seriously. For this reason, we only sell CAT5e cables with guaranteed transmission rates and ETL, UL and CSA certification. We also perform Fluke testing on all of our cables to ensure their quality, as well as backing our cables with a lifetime warranty.
