PANDA and Other Varieties of Polarization Maintaining Fiber

Polarization maintaining fiber, also known as polarization preserving or HiBi (high birefringence) fiber, can be produced in various configurations. In addition to the PANDA style used by Nufern, other designs such as elliptical core, elliptical clad, and bow-tie forms have been tried.

The PANDA construction methodology allows the independent control of the optical core, and the stress rod size, location, and composition. These four independent variables absolutely dictate the performance superiority of a PANDA-style fiber design over all competing technologies for maintaining the polarization state of light in an optical fiber.

Largest family of Polarization Maintaining Passive, Active, and Sensor fibers

Nufern's PANDA fibers incorporate the best attributes of single-mode fiber manufacturing, which lends itself to lower cost through large scale production. This facilitates the highest possible proof stress strength and fatigue failure resistance, along with extremely uniform optical and mechanical properties.

NuPANDA™ polarization maintaining optical fibers are available for a variety of applications. The possibilities include:

These fibers can be supplied in form factors from 80 up to 400 µm depending upon the configuration.
