  • Page 67 T-Cube NanoTrak Autoalignment Controller However, piezo transducers are unip olar and to achieve a positive an d negative adjustment either side of center, the piezo must be at its center of travel when the error signal is zero.

E.2.2 Circle Size and Gain Control Given that move ment of two opposing fibers produces variations in the coupled power, the very act of automatically aligning the fibers to increase the coupled power may cause unwanted disturbances to the signal path.
  • Page 69 T-Cube NanoTrak Autoalignment Controller This LUT diameter adjustment mode allows appropriate circle diameters to be applied on an application specific basis.
