If the tunable laser source module is rack- mounted the temperature and humidity
within the rack apply.
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.
Port separation (static)
Specifies the difference between the power P applied to one port and
the measured power D on any other port with no applied power (dark).
Excluding "Noise pp (dark)" (see,
"Drift (dark)" (see, "Drift (dark)" on page
Powers expressed in dBm, port separation S expressed in dB,
S = P – D

Conditions: Applied power level as specified.
Port separation, dynamic
Specifies the difference between step power input P
or negative slope) applied to one port and the maximum measured
power change D (positive or negative) on any other port without

applied power (dark). Excluding "Noise pp (dark)" (see,
