PCD-M02 Polarization Controller

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.

MEMS-based, Coaxial Style; Fiber Type SM (SMF28ultra, ZBL, SM600/850/980), PM (HP850/908PM); 650 to 1670 nm; Fiber Length 50 to 100 cm; Attenuation up to 30 dB, 40 dB Sercalo Microtechnology’s mVOA series of coaxial ultra-small fiber optic variable optical attenuators (VOAs) is based on an electrostatic MEMS mirror. It comes in a hermetically sealed package with a diameter of only 3.5 mm, and the devices are manufactured with the latest techniques in laser welding for achieving better stability and improved reliability. A voltage between 0 and 6.5 V on the drive pin sets the optical attenuation. When power is removed, the VOA returns into its default state. There are two variants available with different default states: normally open (bright) or high attenuation (dark). The dark variant has better linearity and is used in applications where the light is cut at power off. The mVOA series is designed to conform to Telcordia 1221 reliability standards. No epoxy is present in the optical path. The optical collimator is assembled using laser welding techniques which results in long term stability and excellent reliability. The components withstand rugged environments and can directly be mounted on printed circuit boards. This ultra small mVOA series is compliant to ROHS requirements 2011/65/EU and ideally suited for gain control in amplifiers and transceivers.
