Finisar
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.
