Describe at least three scenarios that a tech would define as a "broken" cable.
What will be an ideal response?
Any combination of the following answers (three minimum) is adequate.
An open circuit in which one or more wires in a cable is not connected from one end of the cable to the other, causing the signal to lack continuity.
One or more of the wires in a cable connects to another wire, causing a short.
One or more of the wires in a cable does not connect to the proper location on the jack or plug.
The electrical signal bleeds from one wire pair to another (crosstalk), creating interference.
The cable is picking up noise, usually caused by faulty hardware or poorly crimped jacks.
If cables of different types are connected, the flow of electrons is not uniform, causing a unique type of electrical noise called an echo. This is an impedance mismatch.
