Optical Power Budget

The allowed link length is calculated from the optical power budget (OPB), the available optical 
power for a fibre-optic link, and the attenuation of the fibre, comprising losses due to in-line  
connectors, splices, optical switches and a margin for link ageing (typical 1.5 dB for 1300 nm).
The worst-case optical power budget (OPB) in dB for a fibre-optic link is determined by the differ-
ence between the transmitter’s output optical power (min) and the receiver input sensitivity (max).
