What is inductace? - correct answer-1) The property of an electrical force field built
around a conductor when current flows through it. 2) The resistance to change in
current.
What is impedance? - correct answer-The total opposition (resistance and reactance
[capacitance and inductance]) that a circuit, cable or component offers to the flow of
alternating current (ac) at a given frequency. It is measured in ohms.
What is hearing range for humans? - correct answer-20 Hz- 20,000 Hz
What is modal dispersion? - correct answer-A characteristic of transmission in an
optical fiber that results from different lengths of the light paths taken by the many
modes of light as they travel down the fiber from source to receiver. Also called
modal distortion.
What is chromatic dispersion? - correct answer-A result of the phenomenon that the
velocity of propagation in a medium is frequency dependent, which causes the
frequency components of a pulse to lose phase coherence as it propagates
(transmitted pulse will spread out as it propagates)
What is a code? - correct answer-"A rule or set of rules intended to ensure safety
during the installation and use of materials, components, fixtures, systems,
premises, and related subjects." Codes typically are invoked and enforced through
government regulation.
A code ensures the:
-Practical safeguarding of persons and property from hazards.
-Quality of construction
What is a standard? - correct answer-Is an accepted collection of requirements and
recommendations for the defining, construction, evaluation, application or
comparison of materials, equipment, products and services.
Also to ensure a minimum level of acceptable performance.
What is a regulation? - correct answer-is an authoritative rule that controls or
governs behavior leading to uniformity.
What is SCS? - correct answer-Structured Cabling System
, What is MC (CD)? - correct answer-Building or campus serving cross connect in the
ER for connecting entrance cabling, backbone cabling, and equipment cabling.
Main cross connect/ campus distributor
What is IC (BD)? - correct answer-Building-serving cross-connect points located
between the MC (CD) and HC (FD) in interbuilding backbone cabling.
Intermediate cross connect/ building distributor
What is HC (FD)? - correct answer-Floor-serving location for the cross connection of
horizontal cabling to other cabling and equipment.
Horizontal cross connect/ floor distributor
A first level backbone consists of: - correct answer-cabling that is installed between
an MC (CD) and an IC (BD) or a horizontal cross-connect (HC [floor distributor
(FD)]).
A second level backbone consists of: - correct answer-is a cable that is installed
between an IC (BD) and an HC (FD).
The color....Orange - correct answer-Demarcation Point
The color....Green - correct answer-Network Connections (network, auxiliary
equipment)
The color....Purple - correct answer-Common equipment (connections to PBX,
mainframe computer, LAN, multiplexer)
The color....White - correct answer-First level backbone (termination of building
backbone cable connecting MC [CD] to ICs [BDs])
The color....Gray - correct answer-Second level Backbone (termination of building
backbone cable connecting ICs [BDs] to HCs [FDs])
The color....Blue - correct answer-Horizontal cable ( horizontal connections to
telecommunications outlet/connectors, formerly referred to as "station cable"
The color....Brown - correct answer-Interbuilding backbone (campus cable
terminations)
* Brown takes precedence over White or Gray for interbuilding runs
