PANDA Fibers: Key Attributes

Radiation Performance

Because the optical core is manufactured independently of the stress rods, it can be made with high chemical purity. This allows for an intrinsic radiation performance benefit not inherent in the best radiation resistant PM fibers made with competing technologies.

Alignment & Splicing Performance

Stress rods—which induce the polarization maintaining effect in the fiber—are inserted into circular holes drilled into the pristine preform. As such, splicing and coupling can be done with a high degree of accuracy, with closer tolerance and greater repeatability than fiber made with other designs. This uniformity ensures lower splice loss and higher extinction ratios.

Polishing

Many applications require the termination of a PM fiber. To ensure good optical performance, the core, clad, and stress area must accept a proper polish. Nufern's PANDA fiber can be polished to a higher degree of uniformity than other polarization maintaining fibers without risk of damage.

Coiling & Mechanical Strength

Many sensor applications require that the PM fiber is tightly and compactly coiled. The consistency of Nufern PANDA fiber over length is unsurpassed, and so can form more uniform coils than previously achievable. Additionally, the absence of low strength breaks results in the longest life expectancy in deployment versus any competing technology.
