|UTP Cabling Testing|
|After installation, Category 3 and Category 5 UTP cabling shall be tested for the following parameters:|
* Wire Map;
* Near-end crosstalk (NEXT).
Category 5E cabling requires additional testing for the following parameters:
* Power sum NEXT;
* Power sum equal level far-end crosstalk (PSELFEXT);
* Return Loss.
These tests (except Wire Map) require an advanced field cable tester that may be too expensive and complex for the normal home network user. In case of problems after installation, it is recommended to thoroughly check that all UTP installation requirements are met. A local cabling contractor can also be contacted for providing cabling testing with a cable tester.
A simple and inexpensive device for checking Wire Map can also be very useful.
