Glossary
Crosstalk
C
C-5
Crosstalk
Unwanted signal transfer between adjacent cable pairs. Crosstalk occurs because electrical
signals passing through a cable pair create an electromagnetic field that transmits the
signal to nearby pairs.
CSV Data
Abbreviation for comma-separated variable. A list of data separated by commas. When
CSV data is loaded into a spreadsheet application, the application puts each comma-
separated value into a separate cell.
dB
Abbreviation for decibel. A logarithmic unit used for expressing the loss or gain of signal
strength.

EIA 568A
Electronic Industries Association Commercial Building Telecommunications wiring
standard. See EIA/TIA 568.
EIA/TIA
The US Electronic Industries Association and Telecommunications Industries Association,
which have merged.
EIA/TIA 568
The EIA/TIA Commercial Building Telecommunications wiring standard that defines
generic telecommunications wiring for commercial buildings. The standard covers topics
such as maximum cable lengths, topology, installation practices, and performance
specifications.
Equal Level Far End Crosstalk (ELFEXT)
The difference between the FEXT and the attenuation of the disturbed wire pair (in dB).
Good cable performance corresponds to high ELFEXT values, which result when FEXT is
much higher than attenuation.
