Frequently Asked Questions

What is a 1310nm Polarization Insensitive Isolator?

A 1310nm Polarization Insensitive Isolator is an optical device designed to allow light to pass in one direction while blocking it in the reverse direction, regardless of the light's polarization state. It is commonly used in fiber optic communication systems to prevent back reflection and back scattering, which can degrade signal quality.

What are the key features of the DK Photonics 1310nm Polarization Insensitive Isolator?

The DK Photonics 1310nm Polarization Insensitive Isolator offers low insertion loss, high isolation, optical path epoxy-free design, low polarization dependent loss (PDL) and polarization mode dispersion (PMD), high reliability, and excellent temperature stability.

What applications are suitable for this isolator?

This isolator is ideal for use in WDM systems, fiber amplifiers (such as EDFAs and Raman amplifiers), fiber lasers, transmitters, and other fiber optic communication equipment where suppression of back reflection and back scattering is required.

How does a polarization insensitive isolator work?

The isolator utilizes the Faraday Effect of a magneto-optical crystal to guide light in one direction and block it in the reverse direction, independent of the polarization state. This ensures reliable performance in systems where the polarization of light may vary.

Can I request custom specifications for the isolator?

Yes, DK Photonics offers customization options for their isolators, including different fiber pigtails, wavelengths, power handling capabilities, and connector types. You can provide your desired specifications when inquiring to receive a tailored solution.

How does the presence of connectors affect the isolator's performance?

When connectors are added to the isolator, the insertion loss increases by 0.3dB and the return loss decreases by 5dB. Additionally, the power transmitted through the connector should be less than 2W to ensure optimal performance.

What should I consider when ordering a 1310nm isolator from DK Photonics?

When ordering, provide the correct part number and detailed specifications, including desired fiber type, connector type, fiber length, and power handling. If you require a connector, it is not recommended to choose a 250μm bare fiber pigtail. For custom requirements, contact DK Photonics directly for assistance.
