Frequently Asked Questions

What is a 1480nm Polarization Maintaining Isolator and what is it used for?
A 1480nm Polarization Maintaining (PM) Isolator is a two-port micro-optic device designed to allow light to pass in one direction while blocking back reflection and back scattering in the reverse direction. Built with PM panda fiber, it is primarily used in fiber lasers, fiber amplifiers, fiber optic communication systems, and fiber sensors to maintain signal integrity and prevent feedback that could damage sensitive components.
What are the key features of the DK Photonics 1480nm PM Isolator?
The DK Photonics 1480nm PM Isolator offers low insertion loss, high isolation, high extinction ratio, and excellent stability and reliability. It is available with either bare fiber or 900μm jacket cable, and can be customized for specific requirements such as fiber pigtails, wavelengths, and power handling.
How does a polarization maintaining isolator work?
A polarization maintaining isolator uses specialized PM panda fiber to guide light in a single direction, ensuring that the polarization state of the light is preserved. It blocks unwanted back reflections and back scattering, which can interfere with or damage upstream optical components, making it essential for high-performance fiber optic systems.
What are the typical applications of the 1480nm PM Isolator?
Typical applications include fiber lasers, fiber amplifiers, fiber optic communication systems, and fiber sensors. The isolator is especially valuable in systems where maintaining the polarization state and preventing back reflections are critical for performance and reliability.
Can the DK Photonics 1480nm PM Isolator be customized?
Yes, DK Photonics offers customization for their 1480nm PM Isolators, including options for custom fiber pigtails, different wavelengths, power handling capabilities, and connector types. Customers are encouraged to provide their specific requirements for a tailored solution with 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.
How do I specify the correct part number when ordering a DK Photonics PM Isolator?
To specify the correct part number, use the format PMISO-①-②-③-④-⑤-⑥-⑦-⑧ and provide a detailed description of your requirements, including wavelength, fiber type, power handling, fiber length, jacket type, and connector type. For example, PMISO-S-14-P-L-B-90-10-FA describes a 1480nm single stage isolator with specific features. Contact DK Photonics for assistance with custom configurations.
