Fiber Optic Loss Budget
Total link loss (fiber + connectors + splices) and the margin against an application's maximum channel loss (TIA-568 / TIA-526 / IEEE 802.3).
Formula and source
loss = attenuation(dB/km) * length_km + connectors * loss_per_connector + splices * loss_per_splice; margin = max_channel_loss - loss; pass when margin >= 0.
Optical link loss budget - fiber attenuation plus connector and splice losses against the application's maximum channel loss - per the TIA-568 / TIA-526 fiber-test methods and the IEEE 802.3 channel-loss limits, by name; first-principles.
