Polarization Maintaining Fiber
A Polarization maintaining fiber (PMF) output is standard for Keysight
81960A Tunable Laser Source Familys.
PMF is aligned to maintain the state of polarization. A well defined state of
polarization helps ensure constant measurement conditions.
The fiber is of Panda type, with TE mode in the slow axis in line with the
connector key.
