In an optical connection apparatus for use in optical connection, a shutter is held by a housing defining an optical axis of the optical connection. A brushless DC motor is design optimized to operate at a design voltage, Vs, along an optimal speedtorque profile. Because the presented calibration procedure needs no new hardware it can be deployed in existing deployments with only a soft-ware upgrade. The system may also include the first filter material coupled to both the second filter material and the third filter material, as well as the second filter material coupled to both the first filter material and the third filter material.
