Given today ’ s competitive landscape , businesses must always be on the lookout for ways to improve data center ( DC ) performance and reliability . As legacy data center hardware and software gets swapped out with modern technologies with the goal of better application performance and stability , one must not forget about the impact this has on the existing DC copper and fiber plants . It ’ s not uncommon , for example , for a brandnew technology to be implemented within a data center only to have it be plagued by connectivity issues , lower than expected speeds and other inconsistencies caused by cabling .

Additionally , data center trends that leverage power over Ethernet ( PoE ) for various IoT purposes within a DC are also on the rise . Common examples include surveillance cameras , LAN-connected door controllers , temperature / humidity sensors and PoE lighting . These additions are creating a much higher demand for PoE within the data center than ever before . Significant increases in the number of PoE connections can cause several unforeseen problems – especially when twisted-pair cable plants were not designed with PoE delivery in mind . The distribution of electricity over copper cables increases heat and electromagnetic interference that can impact individual cables as well as crosscable interference with other twisted-pair runs within a cable bundle .
Because the data center is evolving at an unprecedented rate , it becomes more important than ever to have the right tool or tools for the job , to verify the operational performance of new and existing data center plants . p
