Q

What is the difference between unshielded twisted pair and shielded twisted pair?

A

STP cabling has each copper pair in a layer of braided foil sheathing before being twisted with the other pairs in the cable to reduce electrical interference.

Q

What is plenum?

A

A Teflon-type covering used to cover all types of network cables. Used in cables that may be exposed to extreme heat or have the possibility of releasing gasses into a ventilation system, such as ceilings.
