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).

* Output power is power coupled into a 62.5/125 mm multimode fibre
** Output power is power coupled into a 9/125 mm singlemode fibre
*** The optical power should be reduced by at least 5 dB (SM-LC80 and Bi-di LC-60) or 3dB (SM-LC-40
and Bi-di LC-40) between the optical output and input.
