Modified BoB smith termination for PoE-- Will it work?
The capacitors in series with 75Rs are for blocking the DC power signal to leak thru the 75Rs.

There is no need to parallel the RCs twice, instead connect two RCs to the loaded pairs (A, B: pins 1 &amp; 2, 3 &amp; 6) and other two RCs to the spare pairs (C, D: pins 4 &amp; 5, 7 &amp; 8).  The 10nF's will not save from surge/ESD/fast transients itself, the 1nF/2kV is intended to do this.

In this question it is shown that in modern schemes BS termination has low effect.
