Frequently Asked Questions

What is a 1550nm Polarization Maintaining Isolator and what is it used for?
A 1550nm Polarization Maintaining (PM) Isolator is a micro-optic device designed to allow light to pass in one direction while blocking it in the reverse direction, specifically for light at the 1550nm wavelength. It is built with PM panda fiber to maintain the polarization state of the transmitted light. This isolator is commonly used in fiber lasers, fiber amplifiers, fiber optic communication systems, and fiber sensors to prevent back reflection and back scattering, which can degrade system performance.
What are the key features of the DK Photonics 1550nm PM Isolator?
The DK Photonics 1550nm PM Isolator features low insertion loss, high isolation, high extinction ratio, and excellent stability and reliability. It is available with either bare fiber or 900um jacket cable and can be customized for different wavelengths, fiber pigtails, and power handling requirements.
How does a polarization maintaining isolator work?
A polarization maintaining isolator works by allowing light to travel in one direction while blocking light traveling in the opposite direction. It uses PM panda fiber to preserve the polarization state of the light, ensuring minimal signal degradation. This is essential in applications where maintaining the polarization is critical, such as in fiber lasers and amplifiers.
What are the typical applications for a 1550nm PM isolator?
Typical applications for a 1550nm PM isolator include fiber laser systems, fiber amplifiers, fiber optic communication networks, and fiber optic sensors. It is used wherever it is necessary to prevent back reflections and maintain the polarization state of the optical signal.
Can the DK Photonics PM isolator be customized for specific requirements?
Yes, DK Photonics offers customization for their PM isolators, including different wavelengths, fiber pigtails, connector types, and power handling capabilities. 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 the insertion loss will be 0.3dB higher, return loss will be 5dB lower, and extinction ratio will be 2dB lower compared to a device without connectors. The default connector key is aligned to the slow axis, and power transmission through the connector should be less than 2W. For pulse applications, inform DK Photonics of the pulse energy and peak power.
