FPS-001 Phase Shifter

3 Stage Scramblers or 4 Stage Controllers Available; 1250 to 1650 nm (Others on Request); Insertion Loss <0.4 dB; Polarization Dependent Loss <0.06 dB; Fiber Type SM OZ Optics' EPC series of electrically driven polarization controllers provides a simple, efficient means to manipulate the state of polarization within a single mode (SM) fiber. Employing a novel mechanical fiber squeezing technique, the device is controlled by either three or four (depending on the model) input voltages that the user can vary over a ±5 V range to provide endless polarization control in a robust, easy to operate package. The EPC controllers’ rapid response speed easily handles changes in polarization caused by the external environment and is highly suitable for polarization scrambling for either averaging PDL effects or for making PMD or PDL measurements. Because the fiber within the device is continuous, all insertion losses, return losses, and PDL effects are limited only by the fiber itself. This makes it ideal for precise test and measurement applications. EPC polarization controllers are available in either a three or four channel configuration. The EPC-300 three-channel system is ideal for polarization scrambling applications such as for polarization averaging or PDL measurements. The added redundancy of the EPC-400 four-channel version opens the way to continuous polarization control, without having to occasionally reset the device when a controller reaches its limit. The unique design of the OZ Optics EPC series of polarization controllers means that they do not require any dedicated driver circuitry. There are no internal voltage multipliers or high voltage signals to worry about. Thus operation is safe and simple.
