PM Coupler

Free space isolator

 

Free space isolators are used in the high-speed optical transmitter or other pump laser which need to isolate the backward light. The isolators offer excellent performance with high isolation and low insertion loss. Available in single stage or semi-double stage options are centered at 1310nm, 1490 or 1550nm.


The free space isolators can offer a range of clear aperture diameters from 0.40mm to 1.5mm as standard. Packaging options include square round or U shaped housings.


The products are Telcordia GR-1221-CORE qualified.
