In the LLC equation, Power penalties account for what type of losses?

Power penalties in the LLC equation represent extra losses caused by device non-idealities. In a real link, components don’t behave perfectly—transmitters, receivers, and interfaces introduce distortion, nonlinearity, impedance mismatches, finite extinction ratios, and other imperfections that reduce usable power beyond the straightforward, predictable attenuation of cables and connectors. The penalty term is added to the link budget to reflect these inevitable degradations and to ensure there’s enough margin to meet the required performance (such as a target BER). This is different from passive cable attenuation, which is a known, length-dependent loss, and from transmitter power or receiver gain, which are about boosting signal rather than accounting for extra loss.
