Summary:A method and system for detecting transformer saturation in a communication interface is provided. The method may include detecting a change in impedance resulting from transformer saturation of at least one isolation transformer utilized in a network path of a network. The network may conform to an IEEE 802.3af specification where power may be delivered through the network. The method may further comprise generating a pulse at a one end of the network and measuring a reflection at that end to detect the transformer saturation. In response to the impedance change, a transmitter signal may be pre-distorted in order to compensate for the detected transformer saturation, or the power delivered over the network may be disabled.
