BICSI Installer 2 copper study Questions and Answers graded A+
latest update
The ratio of the speed of transmission along a cable relative to the speed of light in a vacuum
Some key factors in establishing a good connection and minimizing loss of signal include
Fit
Alignment
Functionality
Configuration
Connectors
Connecting hardware is often referred to as
All category/class rated cable
Generally, have a characteristic impedance of 100 ohm
Near-End Crosstalk (NEXT)
Is a measure of the unwanted signal coupling from transmitter at the near end into another pair
measured at the near end
Attenuation-to-Crosstalk Ratio, Far-end (ACRF)
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
(ACRF)
Is measured and expressed in decibels at the opposite end from which the source signal is
transmitted
Alien crosstalk (AXT)
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
What does 8P8C stand for?
8-position, 8-contact
Codes as adopted in part by the FCC are
RJ- Registered jack
C- Flush-or surface-Mount jack
W- Wall-Mount jack
, X- complex or multi-lone connector
The FCC code RJ means
Register Jack
There are four classes of administration of Structure cabling system (SCS)
Class 1 single ER equipment room
Class 2 multiple
telecommunication spaces
Class 3 multiple buildings on campus
Class 4 multiple sites
Endothermic
Ability to absorb heat
3 basic types of crosstalk of interest for balanced twisted pair
Near End (NEXT)
Attenuation to crosstalk far end (ACRF)
Alien crosstalk
intumescent
Ability to expand heat
Three transmission methods are
Simplex
Half duplex
Full duplex
Simplex
Transmits signals in one direction
Half Duplex
Transmits signals in either direction but only One Direction at a time
Direct current (DC)
