Active Circuit - CORRECT-ANSWERSAny circuit connected to an energized
system.
Active Equipment - CORRECT-ANSWERSThe energized equipment used for
receiving or transmitting analog or digital signals.
Above Finished Floor (AFF) - CORRECT-ANSWERSStandard mounting height
or vertical distance for a fixture, ceiling, device, or any other object
measured from the finished floor surface to the center line of the object as
the measurement point.
Accelerator - CORRECT-ANSWERSA chemical agent used to hasten a
chemical reaction for setting permanent bonds on epoxy glues.
Abandoned Cable - CORRECT-ANSWERSInstalled cables and cabling that are
not terminated at both ends at a connector or other equipment and not
identified with a tag for future use.
Absorption - CORRECT-ANSWERSA phenomenon causing attenuation of wave
signals passing through a medium. It occurs when gaseous molecules or
suspended water particles in the atmosphere absorb the signal energy and
convert in into head due to molecular resonance.
Connectivity - CORRECT-ANSWERSPatch panel, fiber cabling, connectors, and
cable management used to create and maintain electrical and optical
circuits.
Connector - CORRECT-ANSWERSMechanical device used to provide a means
for aligning, attaching, and achieving continuity between conductors or
optical fibers.
Connector Insertion Loss - CORRECT-ANSWERSThe attenuation associate
with the physical attachment of two connectors.
Connector, Small form factor (SFF) - CORRECT-ANSWERSFiber duplex
connector with a footprint aproximating that of an 8-position outlet
connector typically used with 4-pair twisted-pair connectors.
,Consistency Check - CORRECT-ANSWERSMethod of verifying the confidence
of a field measuement.
Consolidation Point (CP) - CORRECT-ANSWERSConnection facility within a
horizontal cabling subsystem for interconnection of fiber extending from
building pathways into furniture pathways or modular wall partitions to the
equipment outlet.
Continuity Tests - CORRECT-ANSWERSTest that validates whether a material
can conduct current or light without significant interruption or degradation.
Continuous Duty - CORRECT-ANSWERSDevice that can operate continuously
with no off or rest periods.
Controlled Environment - CORRECT-ANSWERSTelecom space with humidity,
temperature, floor, and wind controls to proved protected conditions for
sensitive electronic equipment.
Converter - CORRECT-ANSWERSDevice that transfers a signal from one
transmission medium type to another or changes from one signaling type to
another.
Core - CORRECT-ANSWERSThe central, light-carrying part of optical fiber
cable through which a light pulse is transmitted.
Core Hitch - CORRECT-ANSWERSWeaving of copper conductors or pairs
through a pulling eye for pulling the fiber cable.
Corrosion area - CORRECT-ANSWERSSpace that is subject to a high degree or
risk of deterioration to elements.
Coupled Bounding Conductor (CBC) - CORRECT-ANSWERSBonding conductor
placed on the outside surface of telecom cable to reduce transient noise.
Crawl Space - CORRECT-ANSWERSLimited access building space that may be
used for the placement of fiber cabling.
Crimp Head - CORRECT-ANSWERSSection of a splicing rig that fits over an
assembled modular connector on the splicing head to provide the crimping
of the module.
Cross-connect - CORRECT-ANSWERSFacility enabling the termination of cable
elements and their interconnection or cross-connect.
, Cross-connection - CORRECT-ANSWERSConnection scheme between cabling
runs, subsystems, and equipment using patch cords or jumpers that attach
to connecting hardware on each end.
Crosstalk - CORRECT-ANSWERSUnwanted transfer of signal from one or more
circuits to other circuits as a result of electromagnetic interference (EMI).
Curing - CORRECT-ANSWERSTo prepare for use over a period of time by
chemical of physical process.
Current (I) - CORRECT-ANSWERSFlow of electrons in a conductor, measured
in amperes.
Cutsheet - CORRECT-ANSWERSList of pair assignments to specify
circuit/splice connections.
A-C rated fire-retardant plywood - CORRECT-ANSWERSPlywood treated with a
fire-retardant that has a smooth-finished A grade side that is exposed for the
purpose of mounting equipment and a rough-finished C grade side.
Acceptance Angle - CORRECT-ANSWERSThe half-angle of an imaginary cone
extending from the end of an optical fiber cable within which incident light is
totally and internally reflected within the optical fiber core. Light within this
cone is couple into reflected modes of the optical fiber cable. Light striking
the surface of the fiber at an angle greater than the acceptance angle will
not enter the optical fiber cable. Also known as maximum coupling angle.
Acceptance Test - CORRECT-ANSWERSA test or set of tests performed to
demonstrate satisfactory completion of a predetermined task or group of
tasks on which acceptance is dependent.
Access Floor - CORRECT-ANSWERSA system consisting of completely
removable and interchangeable floor panels that are supported on
adjustable pedestals or stringers (or both) to allow entry to the area beneath.
Access Point (AP) - CORRECT-ANSWERS1. The point of entry into a secure
area.
2. A stand-alone hardware device or a computer wireless adapter with
software that acts as a wireless communication hub for users of wireless
devices to connect with each other and to bridge those devices to the cabled
portion of the network.
Access Provider (AP) - CORRECT-ANSWERS1. A company that provides a
circuit path between service providers (SP) and the client user. An AP can be
the SP.
