TruePhase polarization-maintaining fibers are available in a full range of wavelengths. TruePhase fibers utilize industry-standard, stress-applying parts (SAPs) to create two axes in the core, each of which guides light at a different velocity. Crosstalk between those axes is suppressed so that polarized light launched into either axis will remain polarized as it is guided. Detailed specification sheets follow.
