Product Description:

OZ Optics' Electrically Driven Polarization Controller (EPC) provides a simple, efficient means to manipulate the state of polarization within a singlemode fiber. Employing a novel mechanical fiber squeezing technique, the device is controlled by either three or four (depending on the model) input voltages that one varies over a ±5 Volt range to provide endless polarization control in a robust, easy to operate package. The controller's 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.

The polarization controller is available in either a three or four channel configuration. The three channel system is ideal for polarization scrambling applications such as for polarization averaging or PDL measurements. The added redundancy of the 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 Polarization Controller means that it does 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.
