The Category 5e is an upgrade of the Category 4 and can be able to transmit up to 100 MHz. For example, a 4 pair UTP cable should have a bend radius of 1 inch minimum and if lesser bend radius is applied, there will be detrimental effect on the network connectivity. Experts advise that when pulling cables or when inserting them into channels, practice pulling them slowly but surely to prevent any damage to the cables and other installed devices inside the ducts. It has also an added feature of 3db tighter Near End Cross Talk (NEXT) capability than the Cat 4. Problems usually happen when the cables come out of the wall and terminated back to their place which can jam the cables back into their back box. These are the coaxial cable which contains a single copper conductor, the fiber optic cable which consists of a center glass core that can transmit light instead of electronic signals, the unshielded twisted pair (UTP), and the shielded twisted pair (STP). Cat 6 can also run the same length but at least 5 meters should be allowed at terminal ends for the data cabinet. The solution to this is to work the cable back down slowly through the hole in the wall and put BV cable it back carefully where it started.
The UTP has two cable category which are the Category 5e and Category 6 Ethernet cables. The only difference is that the foil on the STP should be properly terminated so that there will be no interruption and interference from other strong signals and the shielding can do what it is supposed to do effectively. Category 6, on the other hand, has transmission characteristic of 250 MHz but with less NEXT unlike Cat 5 and Cat5e. They have specific performance and used on different criteria for hardware and connectors. The UTP and the STP are both copper wired cables but they have different tolerance and sensitivity to interference. However, if you want to use any of these network cables, you have to remember following the right cable length so that the maximum connectivity can be reached. In terms of cabling, also remember that each network cable should follow their bend radius
