You mean cat7 and cat8 bulk cable (no ends)? Yes, they will work great with this type of cable.
Or were you wondering if you can cut a manufactured cable (with ends) and use it with the jacks? I do not recommend doing this ever.
Or do you mean can you simply plug a cat7 or cat8 cable with ends into the jack? Yes, they will work great with all cat5/6/7/8 cables RJ45 which is standard and forwards/backwards compatible.
