2.0μm High Power Polarization Maintaining Optical Isolator
The 2000nm Polarization Maintaining Isolator is a two port micro-optic device built with PM panda fiber. The PM isolator features low insertion loss, high isolation, high extinction ratio and high reliability and stability. The device guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction. The device can be built with bare fiber, or 900um jacket cable. The PM Panda Fiber Isolator is widely used in amplifier systems, fiber optic systems and fiber lasers.
If you do not see a standard isolator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.DK Photonics can respond to custom requirements with short lead times.

*Above specifications are for device without connector.
*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmit through the connector less than 2W.
*For >5W high power applications, we will use heat sink package, contact DK Photonics for details.
*For high-power applications, IL and ISO will be slightly worse due to the heat absorbed by the Faraday plate and the temperature rise. But they are all within a reasonable range. For more information, please contact DKP.
Package Dimension
*Due to ongoing design improvements, the package size is subject to change. Please contact DK Photonics for confirmation.
