Fluke Networks has added a new capability to its DTX CableAnalyzer, which the company says will allow it to validate twisted-pair cabling links that use midspan Power-over-Ethernet (PoE) controllers in accordance with TIA/EIA standards.
DTX AC Wiremap tests the wiring in each link to assure that VoIP phones, wireless access points, security cameras and other PoE devices will work with midspan power supplies before deployment, and to identify failures that may appear after deployment.
“This capability solves a testing issue that has been problematic for Power-over-Ethernet consumers,” said Brad Masterson, product manager, Fluke Networks Canada.
“The ability to properly test through a PoE midspan is essential to certifying modern Ethernet networks.”
Ordinary wiremap tests fail when working with midspan power supplies as the power supplies block the wiremap test signals from flowing in the direction of the Ethernet switch or hub.
The new DTX AC Wiremap test uses alternating current and analysis methods that are unaffected by a midspan supply to provide accurate wiremap tests.
It also diagnosis failures by determining the distance to the point of failure, possible reasons for the failure and corrective actions, saving time and allowing technicians to understand and correct the problem.
According to Fluke, the use of PoE is growing 20% to 30% per year and rapid increase in the use of VoIP phones, wireless access points and other PoE devices has made the powered network essential to businesses.
The Wiremap test is now available on all DTX CableAnalyzers.
