The Optical Power Loss Budget
The maximum length of any optical path between two fiber optic repeaters must becalculated separately, and depends on the total loss in all components used in thepath, including fiber optic cable, optical connectors, star couplers, and splices. Thesum of the losses in all components used in the optical path must not exceed thespecified Power Loss Budget for the chosen cable type.
The specified Power Loss Budget includes the loss of the two ST–type connectorswhich connect at the two repeaters, and also includes the system margin of 3 dB.Thus only other components such as additional connectors, star couplers, and splices,along with cable attenuation, should be taken into account in calculating the loss.
