One of the most common challenges experienced when  working with optical fibers  is polarization dependence. This is a cause for concern, even if the fiber optic cables you’re using are perfectly symmetrical in shape and functionality. The key reason behind this is the mechanical stress applied on the fibers, which makes them lose the symmetry and results in the light polarizing until the wavelengths become highly uncontrollable.

While the fiber quality and temperature have a lot to do with this phenomenon, there are no better solutions than the use of polarization-maintaining fibers to resolve this issue. There are several reasons to invest in polarization-maintaining fibers when looking for fiber optic tools for sale. Here’s everything you should know what they mean and how they work.

The Meaning of PM Fibers

Polarization-maintaining fibers are also referred to as PM fibers. These are a unique classification of single-mode fibers that operate differently from regular fiber cables in the market. PM fibers are manufactured to generate the unified polarization of its input light.

These fibers work by maintaining the polarized light throughout the generation of its waves. They work by preventing the interruption of optical power throughout the transfer to and from polarization modes. Components and devices with external modulators can significantly benefit from polarization-maintaining fibers, primarily because they rely on their light input for optimal operation.

Types of Polarization Maintaining Fibers

Today, the advancement in fiber optic tools  has resulted in a wide range of PM fibers and their different functions. In fact, you can find one that perfectly fits your fiber optic application. Some of the most common types of polarization-maintaining fibers include circular PM fibers, linear PM fibers, linear PM fibers with refractive index modulation, and more.

Applications of Polarization Maintaining Fibers

PM fibers perform a wide range of functions and can be applied to various components. For example, they’re a popular choice in telecommunication modulators that require a light input. Similarly, fiber optic devices that won’t operate without proper control of their polarization states can significantly benefit from PM fibers, especially when looking to keep temperature fluctuations in check.
