I’ll admit, I have used ethernet, but don’t understand the physics behind the limitations of cat5 cable. If you use a Cat5 cable for ethernet, your longest guaranteed transmission length is 100 m according to spec. As far as I can tell, the fathom tether is similar to a Cat5 cable, but can be used with the Fathom-X interface for lengths as long as 300 m.
I am trying to understand how you managed to triple the transmission distance while maintaining wire gauge. Is this due to the engineering of the fathom cable itself or is this also possible with standard Cat5? I know crosstalk usually causes interference between the twisted pairs which causes signal degradation over long distances. Because homeplug only uses one twisted pair, I assume this crosstalk is eliminated. Is the increased transmission distance due to this simple change? If not then what is the reason for the increased transmission distance?
