Steps
Gather the link's components: total fiber length, fiber type (and its attenuation coefficient in dB/km at the relevant wavelength), number of mated connector pairs, and number of splices.
Calculate fiber loss as attenuation coefficient x length using the cable spec's dB/km figure.
Add connector loss: budget roughly 0.3-0.5 dB per mated connector pair unless the manufacturer's tested value is known.
Add splice loss: budget roughly 0.1 dB per fusion splice (higher for mechanical splices) based on the installer's demonstrated splice performance.
Sum fiber + connector + splice loss and compare the total against the applicable TIA-568.3 channel/link loss limit for the fiber category, then also check it against the specific transceiver's optical power budget for margin.
Known gotchas
Loss budgets calculated on paper can still fail in the field if actual splice/connector performance is worse than assumed — field-test with an OLTS rather than relying on the calculated budget alone.
Application (transceiver) power budget and TIA-568.3 channel loss limits are two different numbers — a link can pass TIA-568.3 attenuation limits and still be too lossy for a specific high-speed transceiver's link budget.
