I'm kind of question, what is the protection of these? It not as if he were to land anywhere, and ask that bears little brain if such protection (a) has any effect, and (b) if the effect could even be harmful. The question was prompted, in part, by the fact that I have more than 1 Mbit / s. more with a "flat"-rj11 rj11 me round with a shielded twisted par.Could it be that there is something fundamentally wrong with the twisted pair cable also, I suppose, but I wonder if we are selling shit during the last two meters. After all, unshielded twisted pair in most of the path changes. Certainly, whatever the STP in the last 2m will do is provide more capacitive coupling between the two wires in the pair of utp equivalent that no significant increase in noise reduction, tcp be quite resistant to noise anyway.
