EPC Electrically Driven Fiber Polarization Controllers/Scramblers

3 or 4 Control Channels; 1250-1650 nm, Other; Insertion Loss 0.05 dB; Polarization Dependent Loss <0.06 dB; Fiber Type SM, OtherOZ Optics' EPC-3000 high-speed electrically driven polarization controller provides a simple, efficient means to quickly manipulate the state of polarization within a single mode (SM) fiber. Employing a novel fiber squeezing technique, the device is controlled by either three or four (depending on the model) input voltages to provide endless polarization control and scrambling in a robust, easy to operate package. The EPC-3000 controller's rapid response speed easily handles changes in polarization caused by the external environment and is highly suitable for polarization controlling and scrambling for either averaging PDL, PDG effects, or for making PMD, PDL or DOP 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 the EPC-3000 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, PDL or PDG 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 innovative design of the OZ Optics EPC-3000 high-speed polarization controller provides an integrated module that allows users easily to implement the polarization controller in their systems with both analog and digital inputs.

PMD 0.5 ps; Optical Power Handling 500 mW OZ Optics' EOPC high-speed electro-optic polarization controller is based on a novel, low-loss, high-speed, free-space electro-optic crystal technology. It provides a simple, efficient means to quickly manipulate the state of polarization by applying an external voltage. High-speed polarization state management is enabled using two to four crystals in a row with remarkably low loss, all housed in a compact and robust butterfly package. The device can be offered with 2, 3 or 4 crystals (depending on the customer’s requirement), and by applying external voltages one can change/manipulate/control the output polarization state. For endless polarization control, a device with 4 crystal elements is required, while a 3-elements device will be sufficient for polarization scrambling mode operation. The compact, motionless, and vibration-free design allows fast linear response with less than 10 μs response time to the control signal. The controller's rapid response speed easily handles changes in polarization, caused by the external environment, and is highly suitable for polarization controlling and scrambling to either average PDL and PDG effects, or for making PMD, PDL or DOP measurements. This makes the EOPC device ideal for precise test and measurement applications.
