The total amount of loss in the fiber optic link is calculated by adding up the attenuation accumulated over the fiber, connectors, splices, and other optical components. This number is subtracted from the loss budget to calculate the loss margin. A loss margin of at least 3 dB is recommended to account for future repairs and aging of optical components.
