A Semi-double Stage Isolator Finisar free space isolators offer excellent performance with low insertion loss and 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. Features: High reliability Low insertion loss High isolation Optimized for different wavelengths (1480nm, 1520nm, 1560nm, 1600nm) Wide operating temperature range Applications: The semi-double stage free space isolators are used in various TOSAs, which require higher isolation to prevent feedback into the laser. Specifications: *Note: Over all wavelengths and temperatures. Ordering Information:
