optical isolators can block back lection and backscattering in the reverse direction at any polarization sate. they have low polarization mode dispersion (pmd). the optical path is epoxy-free, thereby enabling high-power applications. they are based on the micro-optics package technology and featured with the best stability and reliability
the products are telcordia gr-1221-core qualified.
