can use OTDR and both of power transmitter and power meter.
To calculate the worst-case estimate of power budget (PB), you assume minimum transmitter power (PT) and minimum receiver sensitivity (PR):
PB = PT – PR
The following hypothetical power budget equation uses values measured in decibels (dB) and decibels referred to one milliwatt (dBm):
PB = PT – PR
PB = –15 dBm – (–28 dBm)
PB = 13 dB
otdr and power meter are the tools used to calculate fiber optics link budget.
Pathloss maybe considered. Thanks
OTDR and Optical power meter
to calculate fiber optic link budget, the use of a power meter and an OTDR is required

1. system link power budget and
2. system rise time budget
power budget (PB) & transmitter power (PT) and minimum receiver sensitivity (PR):
PB = PT values measured in decibels (dB)
PB = PT – PR
