PM Coupler

1480nm Polarization Isensitive Single/Dual Stage Isolator

 

1480nm Polarization Isensitive Single/Dual Stage Isolator 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.
