1. INTRODUCTION
The LANcat Series are precision instruments for the certification
and troubleshooting of LAN cable installations.
With plug-in Performance Modules, the LANcat Series are capable
of testing a wide variety of cable types including
Category 5/Class D twisted pair, coaxial cable, and fiber optic
cable.
This User Manual covers two LANcat Series model configurations.
All models are fully compliant with the testing requirements of the
TIA/EIA 568A TSB-67 and provide Level II measurement
accuracy when testing Category 5 Basic Links.
LANcat OneWay. The OneWay System performs one way near-
end crosstalk (NEXT) measurements up to 100 MHz. Testing of
NEXT from both ends of the link, as now required by TIA TSB-67
for compliant Category 5 installations, is accomplished by
completing separate tests from each end. The test system includes
a main handheld unit and an Active Remote (also called OneWay
Remote).
LANcat TwoWay. The TwoWay System performs automatic bi-
directional measurements of NEXT up to 100 MHz. The test
system includes two LANcat TwoWay handheld units, each having
a full graphic display and control panel. Either unit may be
operated as a main or a remote unit for testing twisted pair links.
