Insertion loss inherently includes both coupling (e.g., light transferred to the other output leg) and excess loss (e.g., light lost from the coupler) effects. The

How does a directional coupler distinguish between forward and reverse

Instead, reverse signals primarily affect the isolated port, where their energy is dissipated or isolated to prevent interference. This directional behavior is quantified by the "directivity" parameter, measuring
