Polarization-sensitive single/dual stage isolator
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.
