Corning’s single-stage and dual-stage optical isolators minimize back reflection and back scattering in the reverse direction at any states of polarization. The polarization insensitive isolator is a low-cost component with excellent performance including low insertion loss, high isolation, high return loss, low PDL,?and PMD. It is available in both C and L band. Corning also offers miniature optical isolators enabling devices to be integrated in very tight modules.?
