* Permitted fiber optic cable length differs according to fiber characteristics, splices, and connectors.
Optical Budget Calculation:
Optical Budget [dB] = Receive Sensitivity – Optical Power – 3 (Aging) – Connectors & Patch Panels Loss
Distance Calculation:
Min Distance = Optical Budget/Maximum Loss
Max Distance = Optical Budget/Minimum Loss
