Using a power meter at the end of a 2 m single-mode fiber patchcord.
Specifies the wavelength range for which no abrupt wavelength change
occurs in
The ambient temperature range and humidity range of the tunable laser
source for which the specifications apply.
If the instrument is rack-mounted, the temperature and humidity within

The insertion loss of the built-in isolator in the backward direction.
This characteristic cannot be measured from outside the instrument. It is
based on known isolator characteristics.
Specifies the ratio of the optical power in the slow axis of a connected
polarization-maintaining fiber to optical power in the fast axis, expressed
in dB
Using a polarization analyzer at the end of a polarization-maintaining
patchcord, by sweeping the wavelength to create circular traces on the
Poincaré sphere. Calculate the polarization extinction ratio from the
diameters of these circles.
