How much frequencies does Cat 7 cable support?



  • Hello, what frequencies does Cat 7 cables support? What's the difference between cat7 and cat7a?



  • Dear Kensudshiodh,

    Cat-7 cabling supports frequencies of up to 600 Mhz and speeds of up to 10,000 Mbit/s. This is a big improvement on previous network cabling speeds (CAT 3: 10 Mhz, CAT 5: 100Mhz, CAT 6: 250 Mhz). Cat 7a cables can perform up to frequencies of 1000 Mhz and 40 Gbit/s.
    CAT7 cables feature even more strict specifications for crosstalk and system noise then CAT 6. This is achieved through shielding on the individual wire pairs and the cable as a whole. Category 7 is recognized for all the country organizations members of ISO.
