Keysight N77xx Series
Optical path blocking
Maximum possible attenuation.
Polarization dependent loss (PDL)
The dependence of the "Total loss" (see,
the input polarization state, expressed as the full difference (in dB)
between the highest and the lowest total loss.
Conditions: Temperature range, input mode as specified.
Measurement: Using high quality connectors in perfect optical
condition.
PDL is a peak-to-peak value.
N O T E
Polarization dependent responsivity (PDR)
Specifies the dependence of the measured power on the input state of
polarization (SOP) as ± half the difference between the highest and the
lowest measured power over all SOPs, expressed in dB.
Powers expressed in dBm.
Conditions: As specified.
