CAT 7 cable differs from preceding Ethernet cable standards including CAT 5 and CAT 6 in several ways, however, one of the greatest advantages of CAT 7 cable is the shielding of its … Better response rate, more barrel flex, and overall higher performance is achieved because of this. New comments cannot be posted and votes cannot be cast. Future proofing. Balance Point. If the cable if 5-10 metres would flat still be suitable or is that past the point of where it starts to get worse? While you don’t end up with quite the “antenna effect” of 7’s, you can actually end up with a shielding reflection problem. Both the CAT8 and CAT8 Connect match their CAT7 predecessors in terms of construction and balance point. So it won't be rare for very long...
