Frequently Asked Questions

What is a 1550nm Polarization Maintaining Isolator?
A 1550nm Polarization Maintaining (PM) Isolator is a micro-optic device designed to transmit light in one direction while blocking back reflections and back scattering in the reverse direction. Built with PM panda fiber, it is optimized for use at the 1550nm wavelength and is commonly used in fiber lasers, amplifiers, sensors, and communication systems.
What are the key features of the DK Photonics 1550nm PM Isolator?
The DK Photonics 1550nm PM Isolator offers low insertion loss, high isolation, high extinction ratio, and excellent stability and reliability. It can be configured with bare fiber or a 900μm jacket cable and is available with custom fiber pigtails, connectors, and handling power options.
What applications are suitable for the 1550nm PM Isolator?
This isolator is ideal for use in fiber laser systems, fiber amplifiers, fiber optic sensors, and optical communication networks where maintaining polarization and preventing back reflections are critical.
How does a polarization maintaining isolator work?
A polarization maintaining isolator uses PM panda fiber to ensure that the polarization state of the transmitted light is preserved. It allows light to pass in the forward direction while blocking light traveling in the reverse direction, thus protecting sensitive components from back reflections and feedback.
Can I request a custom PM isolator for specific requirements?
Yes, DK Photonics offers custom PM isolators tailored to your specifications, including different wavelengths, fiber types, connector options, and power handling capabilities. You can contact their sales team with your requirements for a quote and short lead times.
What should I consider when ordering a PM isolator with connectors?
When ordering a PM isolator with connectors, note that insertion loss will be 0.3dB higher, return loss will be 5dB lower, and extinction ratio will be 2dB lower compared to devices without connectors. The default connector key is aligned to the slow axis, and power transmission through the connector should be less than 2W.
What information is needed to place an order for a DK Photonics PM isolator?
To place an order, provide the correct part number (P/N) according to DK Photonics' ordering information, along with a detailed description of your requirements. If you need a connector, avoid choosing a 250μm bare fiber pigtail, and specify any special needs such as pulse application, fiber length, or connector type.
