1310/1550nm Free Space Isolator (FSIE Series)

Produts Details

Product Name: Free Space Isolator Epoxy (FSIE Series)

AFR's GR-1221 qualified Miniature Free Space Isolators are made by sheet polarizer and YIG crystal bonded together by epoxy. It's commonly used in laser diode packages for telecommunication transmitters. The physical dimensions and optical aperature can be designed to fit your needs. It comes in single stage or semi-double stage for higher isolation or wider temperature range.
