BICSI Installer 2 copper study
(ACRF) - ANS-Is measured and expressed in decibels at the opposite end from which the
source signal is transmitted
110 Blocks come in increments of - ANS-50, 100, or 300 and 900-pair wall mount
3 basic types of crosstalk of interest for balaced twisted pair - ANS-Near End (NEXT)
Attenuation to crosstalk far end (ACRF)
Alien crosstalk
4 common Insulated Displacement Contact (IDC) are? Termination Block Hardware - ANS-•
66-style Block
• 110-style Block
• BIX-style Block
• LSA-style Block
A gauge change of __ numbers approximately doubles or halves the conductor's resistance. -
ANS-3
Alien crosstalk (AXT) - ANS-Is the unwanted signal coupling from a disturbed pair of another 4-
pair cable channel permanent link or component to a disturbed Pair of another 4 pair channel
permanent link or component
All category/class rated cable - ANS-Generally have a characteristic impedance of 100 ohm
Attenuation-to-Crosstalk Ratio, Far-end (ACRF) - ANS-Is the measure of the unwanted signal
transfer that is assistant by applying a signal on one pair at the near and measuring the signal
transfer level on any disturbed pair at the receiving end of the cable
BIX termination blocks assemblies are available in what increments - ANS-50, 250, 300, and
900-pair
Capacitance 1 - ANS-Properties of conductors that allows storage of electric charges when
potential differences (voltage) exist between the Conductors
Capacitance 2 - ANS-Causes a voltage difference between two wires when separated by
insulation
Capacitance is measured in - ANS-Farads
