How to handle fiber optic polarization
By maintaining a high polarization extinction ratio (PER) and reducing polarization-dependent loss and polarization mode dispersion, PM fibers mitigate signal degradation caused by random polarization drift. It should thus fully preserve the polarization of light. In reality, however, some amount of birefringence always results from imperfections of the fiber (e., a slight ellipticity of the fiber core), or from bending. Therefore, the polarization state of light is changed within a relatively short. DIAMOND has developed and perfected the necessary technologies to preserve and control the polarization state of a light signal as it propagates through polarization-maintaining (PM) and polarizing (PZ) optical fibers. Misaligned polarity can lead to communication failures, making it essential to follow best practices. The light is then guided in two perpendicular principle states of polarization with different propagation constants – the fast and the slow axis.
