6-4 Power Monitor Signal Output
The function outputs voltage signal according to integrated power monitor.
It can be used to compensate optical output power fluctuation in real time. (For
example, this feature is best recommended to be used with Santec’s Swept Test
System as WDL/PDL measurement solution.)
Power Monitor
Signal is output from BNC connector leveled “POWER MONITOR” on rear panel.
The relation between output voltage and optical power depends on measurement
range of power monitor, as shown below. Measurement range is adjusted
automatically.
Output voltage value against optical output power is not calibrated.
Typical voltage over output power correlation for each measurement range is shown
below.
Range0: 0.012 V/mW ( > 50 mW )
Range1: 0.06 V/mW ( 10 to 50 mW )
Range2: 0.3 V/mW ( 2 to 10 mW )
Range3: 1.5 V/mW ( 0.4 to 2 mW )
Range4: 7.5 V/mW ( < 0.4 mW )
