Free Space Isolator

Finisar free space isolators are used in various TOSAs, which require isolation to prevent

feedback into the laser. Available in single stage and semi-double stage designs.

Finisar free space isolators offer excellent performance with low insertion loss, high

isolation. Our proprietary bonding process, and years of volume manufacturing experience,

results in a high reliability record. Bare isolator chips survive more than 5,000hrs of damp

heat testing without delamination.
