While any of these possible topologies work well when connection distances are shorter than 1 meter, each topology may present application specific risks as connection distances increase.

To validate the performance of the transformerless implementation, a DP83848 device was configured as represented schematically in Figure 5 using both 0.1 uF and 33 nF capacitors. Standard IEEE compliance testing as well as bit error rate testing was performed. Bit error testing was performed with a traditional link partner, which utilized magnetics, and with a transformerless link partner.

驗證測試（Validation Test）是用 Figure 5 的架構，而且另一邊是有耦合變壓器的。簡單來說，他們就是用 Figure 10(a) 的方式。意思是說，如果你要效果好，在架構上至少用一顆耦合變壓器，不要省到沒天良啦！
