The loss budget of a fiber link is the sum of all expected losses, including fiber attenuation, splices, connectors, and any passive components like splitters in PON networks. For example, a 1,500-meter multimode link with two splices and connectors at each end may have a maximum allowable insertion loss of 6.10 dB at 850 nm and 3.85 dB at 1300 nm .
This proposed metric, link design attenuation (based on typical attenuation), defines a more practical attenuation value that should
