Princetel offers a dual-polarizer based stepper-motor-driven PM fiber VOA that ensures a high level of state-of-polarization
(SOP) stability and very small temperature effect. It also features very low initial insertion loss and high extinction ratio
throughout the tuning range. The precision bipolar stepper motor can be tuned at 0.9 degree steps with a two phase stepper
motor driver (model number: SMD1000).
