PM Coupler

Mini Size 1310&1550nm Polarization Isensitive 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.
