CONCLUSION While the subject of EMI can be very confusing and difficult to understand, there are simple and practical solutions to mitigate its impact on wireline LANs and ensure a very reliable and high QoE, especially when critical video streaming applications are utilized. This can be accomplished without the additional expense of placing optical fiber cables. For electrical pro- tection and lower-frequency EMI issues, the installation of an INT should be considered, especially on longer circuits, LAN circuits for video streaming and other critical computer networking applications, and those OSP cables interconnecting buildings where GPR con- ditions are suspected. When a more suitable INT design is available for LANs, it is possible that it will also be effective in suppressing the higher-frequency AXT issue. Any new installations should seriously consider using STP and a tighter twisted pair, such as Cat 6A. Anything higher than that is already shielded and would be effective in mitigating AXT. An INT would still be required in handling GPR issues on OSP cables and many surge protection problems that traditional surge protectors cannot adequately resolve. AUTHOR BIOGRAPHY: Since January 2014, Russ Gundrum, MBA, PMP, has been the principal consultant at Telecom Problem Solvers, LCC. He assumed this position after retiring from AT&T. As an authority on telecom and computer networking wireline protection problems (e.g., lightning, power induction) and their solutions, Russ wrote his first book on the subject in 1982 and his second in January 2019. He has been an adjunct professor at the University of Houston since 2002, teaching computer networking subjects to graduate and undergraduate students. He is a Life Senior Member of IEEE as well as a member of SCTE and BICSI. Russ can be reached at russgundrum@telecomproblemsolvers.com.
