Category 6A

  • CAT6a is the improved version of the CAT6 cable
  • CAT6a is rated for up to 10Gigabits while CAT6 is only rated for 1Gigabit
  • CAT6a operates at 500Mhz as compared to 250Mhz for CAT6
  • CAT6a has twice the bandwidth of CAT6 cables
  • CAT6a is better at resisting alien crosstalk compared to CAT6
  • CAT6a cables are much thicker compared to CAT6
  • CAT6a costs a lot more compared to CAT6

Category 6

  • Backward compatibility to categories 5e, 5 and 3
  • Open standard that allows products from different vendors to work together
  • Patch cord plug and jack interoperability for modular (RJ-45 type) connections
  • Full system specification including testing of components, patch cords, channels and permanent links
  • Twice the bandwidth of category 5e with positive Power Sum Attenuation to Cross-Talk Ratio (PSACR) up to 200 MHz
  • 23 AWG conductors makes Cat 6 a better system to handle PoE+ (25 Watts per channel)
  • All specifications for components and cabling are tested to 250 MHz
  • Both Category 5e and Category 6 will support Gigabit Ethernet (1000-BaseT)
