Specifications

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.
