Structured Cabling Glossary



Asynchronous Transfer Mode (ATM): Technology selected by the International

Telecommunications Union (ITU, formerly CCITT) for broadband ISDN. This

communications protocol is also specified by The ATM Forum (Foster City, CA) for

155 Mb/s transmission over twisted-pair cable and various bit rate optical fiber

cabling applications.

Attenuation: A reduction in power or amplitude of the

transmitted signal. In cables, it is generally expressed in decibels per unit

length.

Attenuation to Crosstalk Ratio (ACR): The difference

between attenuation and crosstalk measured in decibels.

Auxiliary Disconnect Outlet (ADO): A device usually

located within the tenant or living unit used to terminate the ADO cable or

backbone cable.

Auxiliary Disconnect Outlet (ADO) Cable: In residential

applications, the cable from the auxiliary telecommunications disconnects

outlet/connector or the distribution device in a customer's premises to the

backbone facility or the point of demarcation.

Balun: A transformer device used to convert unbalanced

coaxial signals to balanced signals.

Break Test Access: Method of disconnecting a circuit that

has been electrically bridged to allow testing on either side of the circuit

without disturbing cable terminations. Devices that provide break test access

include: disconnect blocks, bridge clips, plug-on protection modules, and

plug-on patching devices.

Bridged Tap: The multiple appearances of the same cable

pair or fiber at several distribution points. Also known as parallel

connections.

Bridging: A means of providing through connections

between conductors or pairs that are terminated on connecting blocks. These

through connections are commonly provided by means of individual metallic

"bridging" clips or multiple "bridging" clips that are

housed in a plastic insulator.

Bundled Cable: An assembly of two or more cables

continuously bound together to form a single unit prior to installation

(sometimes referred to as loomed, speed-wrap or whip cable constructions).

Campus Backbone: Cabling between buildings that share

telecommunications facilities.

Collapsed Backbone: A local area network configuration

wherein bridging and routing functions are located at the main cross-connect and

accessed via optical fiber (usually 2 or 4). Concentrators (twisted-pair to

fiber) remain at the horizontal cross-connects.

CRC (Cyclic Redundancy Checking): A very reliable error

detection system, CRC is 99.99995 percent accurate in detecting transmission

errors. CRC is normally used on blocks or frames of data rather than individual

bytes, and relies on frame check sequence (using mathematical algorithms) which

provides the means to check for errors.

Cross-connect: A facility enabling the termination of

cables as well as their interconnection or cross-connection with other cabling

or equipment. Also known as a distributor.

Cross-connection: A connection scheme between cabling

runs, subsystems and equipment using patch cords or jumpers that attach to

connecting hardware on each end.

Crosstalk: Noise or interference caused by

electromagnetic coupling from one signal path to another. Crosstalk performance

is generally expressed in decibels.

Decibel (dB): A standard unit for expressing transmission

gain or loss as derived from a ratio of signal amplitudes or power.

Delay Skew: The difference in propagation delay between

the fastest and slowest pair in a cable or cabling system.

Electromagnetic Compatibility (EMC): The ability of a

system to minimize radiated emissions and maximizes immunity from external noise

sources.

Electromagnetic Interference (EMI): The interference in

signal transmission or reception caused by electromagnetic radiation generated

by other equipment or cabling.

Equal Level Far-end Crosstalk (ELFEXT): Crosstalk

measured at the opposite end from which the disturbing signal is transmitted

normalized by the attenuation contribution of the cable or cabling.

Far-end Crosstalk (FEXT): Crosstalk measured at the

opposite end from which the disturbing signal is transmitted.

FC Connector: A type of optical fiber connector

identifiable by its round, screw-operated locking nut. It is usually metal. Its

ruggedness leads it to be widely used in test equipment.

Fiber Distributed Data Interface (FDDI): Operates at 100

megabits per second (Mb/s). Developed by the ANSI X3T9.5 committee. This is a

token-passing dual-ring architecture that provides redundancy using fiber optic

cable with transmission up to 2 kilometers.

Firestop: A material, device, or assembly of parts

installed in a cable pathway at a fire-rated wall or floor to prevent passage of

flame, smoke or gases through the rated barrier (ex: between cubicles or

separated rooms or spaces).

Floor Distributor (FD): The international term for

horizontal cross-connect. The distributor used to connect between the horizontal

cable and other cabling subsystems or equipment.

Home-run Cabling: A distribution method in which

individual cables are run directly from the horizontal cross-connect to each

telecommunications outlet. This configuration is also known as star topology.

Horizontal Cabling: The cabling between and including the

telecommunications outlet and the horizontal cross-connect.

Horizontal Cross-connect (HC): A cross-connect of

horizontal cabling to other cabling, e.g., horizontal, backbone, or equipment.

Hybrid cable: An assembly of two or more cables, of the

same or different types or categories, covered by one overall sheath.

Insertion loss — (1). The loss resulting from the

insertion of a device in a transmission line, expressed as the reciprocal of the

ratio of the signal power delivered to that part of the line following the

device to the signal power delivered to that same part before insertion. (2). In

an optical fiber system, the loss of optical power caused by inserting a

component, such as a connector, coupler or splice, into a previously continuous

optical path.

Intelligent Hub: A hub that performs bridging and routing

functions in a collapsed backbone environment.

Jumper Wire: An assembly of twisted-pairs without

connectors on either end used to join telecommunications links at a

cross-connect.

Longitudinal Conversion Loss (LCL): A measure (in dB) of

the differential voltage induced on a conductor pair as a result of subjecting

that pair to longitudinal voltage. LCL is considered to be a measure of circuit

balance.

Main Cross-connect (MC): A cross-connect for first level

backbone cables, entrance cables, and equipment cables.

MAU: (1). Multi-station Access Unit in reference to Token

Ring. (2). Medium Attachment Unit in reference to Ethernet A wiring concentrator

used in Local Area Networks. A device that allows terminals, PCs, printers, and

other devices to be connected in a star-based configuration to Token Ring or

Ethernet LANs. MAU hardware can be either active or passive and is not

considered to be part of the cabling infrastructure.

Multimode Optical Fiber: An optical fiber that will allow

many bound modes to propagate. The fiber may be either a graded-index or

step-index fiber. Multimode optical fibers have a much larger core than

single-mode fibers. See also Optical Fiber Cable.

Near-end Crosstalk (NEXT): Crosstalk measured at the end

from which the disturbing signal is transmitted.

Outlet/Connector, Telecommunications: A connecting device

in the work area on which horizontal cable terminates.

Patch Cord: A length of cable with connectors on one or

both ends used to join telecommunications links at a cross-connect.

Patch Panel: Connecting hardware that typically

provides means to connect horizontal or backbone cables to an arrangement of

fixed connectors that may be accessed using patch cords or equipment cords to

form cross-connections or interconnections.

Plenum: A compartment or chamber to which one or more

air ducts are connected and that forms part of the air distribution system.

Propagation Delay: The amount of time that passes

between when a signal is transmitted and when it is received at the opposite end

of a cable or cabling.

Punch Down: A method for securing wire to a quick clip

in which the insulated wire is placed in the terminal groove and pushed down

with a special tool. As the wire is seated, the terminal displaces the wire

insulation to make an electrical connection. The punch down operation may also

trim the wire as it terminates. Also called cut down.

Quick Clip: An electrical contact used to provide an

insulation displacement connection to telecommunications cables.

Return Loss: Return loss is a measure of the signal

reflections occurring along a channel or basic link and is related to various

electrical mismatches along the cabling.

Screened twisted-pair (ScTP): A balanced twisted-pair

cable surrounded by metallic braid, foil (screen) or both and bound in a single

cable sheath.

Shielded twisted-pair (STP-A): A cable surrounded by a

metallic braid, foil or both and bound in a single plastic sheath containing

balanced twisted-pair conductors that are individually shielded.

Single-Mode Optical Fiber: An optical fiber that will

allow only one mode to propagate; this fiber is typically a step-index fiber.

(Source ANSI/TIA/EIA-568-A)

Sneak Current: A low-level current that is of

insufficient strength to trigger electrical surge protectors and, therefore, is

able to pass through them undetected. These currents may result from contact

between communications lines and AC power circuits or from power induction, and

may cause equipment damage unless secondary protection is used.

Surge: A rapid rise in current or voltage, usually

followed by a fall back to a normal level. Also referred to as transient.

Tip Conductor: A telephony term used to describe the

conductor of a pair that is grounded at the central office when the line is

idle. This term was originally coined from its position as the first (tip)

conductor of a tip-ring-sleeve switchboard plug.

Transfer Impedance: A measure (in ž) of shield

effectiveness.

Transition Point (TP): A location in the horizontal

cabling subsystem where flat undercarpet cabling connects to round cabling.

Trunk: A communication line between two switching

systems. The term "switching systems" typically includes equipment in

a central office (the telephone company) and PBXs. A tie trunk connects PBXs.

Central office trunks connect a PBX to the switching system at the central

office.

Unshielded Twisted-Pair (UTP): A cable with multiple

pairs of twisted insulated copper conductors bound in a single sheath.

Work Area Cable: A cable assembly used to connect

equipment to the telecommunications outlet in the work area. Work area cables

are considered to be outside the scope of cabling standards.
