WSP's PM Fiber Faraday Mirrors are designed to preserve the input PM light with high fidelity and with lowest possible insertion losses.
In a fiber Faraday mirror, the linearly polarized light travels in along a specific fiber polarization axis and reflected back along a 90 rotated, orthogonal direction. It can be used to compensate polarization mode dispersion (PMD) and to cancel other polarization related effects
WSP's fiber Faraday mirrors are distinguished with their high isolations, wide fiber selection, and high polarization extinction ratios.
