Polarization controllers manually produce various polarization states by rotating two axes of λ/2 and λ/4 plates. This product combines them as units and can hold up to 8 units in a 3U rack. This product is recommended to be used when testing each channel.


– Low loss, low loss fluctuation, and high return loss
– All units are compatible with other optical delay lines and wavelength tunable filter units, and they can be arbitrarily combined within a rack.
