DOP-201 : Degree of Polarization Meter

The LUNA DOP-201 uses a low activation loss fiber squeezer polarization controller in conjunction with a patented maximum-minimum search method that allows it to unambiguously measure both low and high DOP values in 30 ms, and to operate over a wide wavelength range. Simultaneous measurement of DOP and optical power level of the light source under test can be used to obtain DOP power dependence and to ensure low insertion loss during depolarizer manufacturing.
