Cable Testing for Existing Category 5 Cable
Installed Category 5 cabling must pass tests for Attenuation, Near-End
Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing
information is specified in the ANSI/TIA/EIA-TSB-67 standard. Cables
must also pass test parameters for Return Loss and Equal-Level Far-End
Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/
EIA-TSB-95 Bulletin, "The Additional Transmission Performance
Guidelines for 100 Ohm 4-Pair Category 5 Cabling."
Note that when testing your cable installation, be sure to include all patch
cables between switches and end devices.
