Are the connectors for Cat5e and Cat6 different? Why are they more expensive?


Cat6 and Cat5e connectors may look alike, Cat6 connectors have much better transmission performance. For example, at 100 MHz, NEXT of a Cat5e connector is 43 decibels (dB), while NEXT of a Category 6 connector is 54 dB. This means that a Cat6 connector couples about 1/12 of the power that a Category 5e connector couples from one pair to another pair. On the other hand, you could say that a Cat6 connector is 12 times less "noisy" compared to a Cat5e connector. This huge improvement in performance was achieved with new technology, new processes, better materials and significant R&D resources, leading to higher costs for manufacturers.
