Finisar Features: ● High reliability Free Space Isolator ● Low insertion Loss ● High Isolation ● Optimized for different wavelengths ● Wide operating temperature range 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.
