What are the three phases of testing? - correct answer - Phase 1
- visual verification
Phase 2 - testing cables with correct equipment
Phase 3 - documentation
What are the uses of a TDR - correct answer - identify cable
defects, splices, and connectors
Is a high or low L rating better for fire stopping - correct answer -
low
What are the three basic properties associated with non-
mechanical fire stopping? - correct answer - intumescent
endothermic
ablative
What is the main property associated with mechanical fire
stopping? - correct answer - Elastomeric
, Page | 3
What is the most common fire protection principle? - correct
answer - Compartmentation
Fire safety must provide - correct answer - containment

suppressant
What property allows a fire stop to develop a hard char and
become rigid when exposed to heat? - correct answer - ablative
25-pair color code - correct answer - White - Blue, orange, green,

NVP - correct answer - Nominal Velocity of Propagation
Insertion loss - correct answer - The difference in the amount of
power received before and after something is inserted into the
circuit.
Resistance - correct answer - Resistance is expressed in Ohms,
and is the property of a conductor to resist the flow of electricity
through it. V=IR
Inductance - correct answer - Is a property of an electromagnetic
field built around a conductor that opposes any change in the
current flow in a circuit
Capacitance - correct answer - is a property of conductors that
allows storage of electric charges when potential differences exist
between the conductors.
Impedance (V) - correct answer - Total opposition of current flow
measured in Ohms
