Hi, Can I connect the power, DSL, and phone cable into my Surge Protector? Will it eat up my DSL speed or cause my modem to lose max attainable bit rate?
How much capacitance in that protector? Increased capacitance causes signal losses.
Meanwhile, all telcos already install a protector for free where their wires meet yours. A protectors designed to not degrade DSL signals.
What are you trying to do? Do you think that silly little box by itself will stop what three miles of sky could not? Do you think its tiny little components will stop a surge of hundreds of thousands of joules? What do you want to do?
View what another has recently seen:
A protector simply connects a surge to all other wires. If connected within feet of earth, then a surge is harmlessly absorbed by earth. If too far from earth and adjacent to electronics, then the surge has more paths to find earth destructively via the appliance.
Don't take my word for it. View its manufacturer numeric specs. Show us where it even claims protection from each type of surge. It does not.
Why does your telco install that protector for free? Because the superior protector costs so little money. And can be earthed. A protector is only as effective as its earth ground.
Meanwhile, what is the largest source of DSL damage? Incoming on AC mains. Surges seek earth ground. One perfect path is incoming on AC mains, destructively through your DSL equipment, and to earth ground via the phone line. Why? The phone line is already connected to earth via the telco provided surge protector. But you caused the damage. You permitted a surge inside the building. You did not earth a 'whole house' protector at the breaker box.
What are you trying to accomplish? Surge protection? Or do you just assume something called a surge protector must be surge protection. A protector is nothing more than a connecting device. Surge protection is earth ground. If you want surge protection, fix what is protection.
