Frequently Asked Questions

What is a 1310nm Polarization Maintaining Isolator?
A 1310nm 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 1310nm wavelength and is commonly used in fiber lasers, amplifiers, sensors, and communication systems.
What are the key features of the DK Photonics 1310nm PM Isolator?
The DK Photonics 1310nm PM Isolator offers low insertion loss, high isolation, high extinction ratio, and excellent stability and reliability. It can be configured with bare fiber or 900μm jacket cable and is available with various connector options.
What applications are suitable for the 1310nm 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 one direction while blocking light traveling in the opposite direction, thus protecting sensitive optical components from back reflections and feedback.
Can I order a custom 1310nm PM Isolator with specific requirements?
Yes, DK Photonics offers custom PM isolators tailored to your specifications, including different fiber pigtails, connector types, wavelengths, and power handling capabilities. Contact their sales team with your requirements for a quote and short lead times.
How do connectors affect the performance of the PM Isolator?
When connectors are added, the insertion loss increases by 0.3dB, the return loss decreases by 5dB, and the extinction ratio decreases by 2dB 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.
What information do I need to provide when ordering a 1310nm PM Isolator?
When ordering, provide the correct part number (P/N) according to DK Photonics' ordering information, including details such as wavelength, fiber type, power handling, fiber length, jacket type, and connector type. For pulse applications, specify the pulse energy and peak power.
