I've spent this morning mostly terminating cat5e cable in krone blocks. Mind numbingly dull, it lead me to wonder why some cables have a cotton or nylon string in them? The only reason I can see for it is merely to irritate the user, but maybe there's a real purpose. Can anyone shed any light on it??
