Fiber-coupled polarimeter plug-in module
Features:
– Four Stockes parameters measurements
– Instantaneous state of polarization (SOP)
– Degree of polarization of input light (DOP)
– Three different displaying modes: Jones graph, Poincaré sphere and Stockes parameters oscilloscope
– Extinction ratio measurements of polarizers or alignement of PM fiber
– Very low PER measurement coming soon!
The A3321A fiber-coupled polarimeter enables real time monitoring of the SOP, DOP, and power of a light signal in fiber.
It can display SOP data information either on a Poincaré sphere, a Jones diagram or on a virtual oscilloscope. Covering the operating wavelength range from 1520 to 1610nm, it offers excellent performance, fast sampling rate, high SOP accuracy, and wide dynamic input optical power range.
