5.6 DualMODE™ Function for Twisted Pair Cabling
The DualMODE™ function of LanTEK
®
III Cable tester allows measurement in compliance with
2 limits in one single Autotest. Thus, for instance, simultaneous Channel Link and Permanent
Link measurements can be performed.
With DualMODE™ it is possible to perform other important tests. Let us assume you are
installing a Cat-6 system in a country whose government agency uses a national standard
based on ISO. But you are working with cables and connection components manufactured
by a company in the US. The government agency can request a certification according to
ISO Class E from the installer. However, for warranty reasons the US company might insist
on TIA 568 Category 6. Therefore, in the past both certifications were required - in
compliance with ISO and TIA - and the increased costs had to be passed on to the
customer. In contrast, DualMODE™ makes it possible to perform both certifications at the
same time, in compliance with ISO Class E Permanent Link and TIA 568B Category 6. The
costs are the same as for one test.
Another example for the use of DualMODE™ is the calculation of margins in relation to
higher bandwidth for future applications. Up to now you had to check the certification
documents for Category 6 Permanent Link and assess whether adequate margins for
transmission of applications at higher bandwidth are available. However, assessment of the
complete final data would also require a certification according to Category 6
A
. Due to
higher test costs, these measures would usually not be performed.
With DualMODE™ you can certify the system in compliance with Category 6, and perform
tests with the limits of Category 6
A
. Due to unmistakable data, your customer would know
exactly what cable lines support higher bandwidths in future applications. This information
would be of great importance when making a decision on whether to assemble cables with
connectors of a higher category, or to pull in cables of a higher category.
5.6.1 Implement DualMODE™
