This presentation will review metallic noise issues on customer POTS lines in Tallahassee, Florida caused by the harmonic interferences induced into the local copper communications cable when a new solar farm was placed into service. These harmonics where at a frequency level not easily mitigated using standard practices. Work Performed and analyzation of the harmonic frequencies along with details of what was done to mitigate them will be discussed.
