Isolator Type：Singgle Stage / Dual Stage
Grade：P-grade / A-grade
Operating Temperature：-40 to +85℃
Free Space Isolators FSI
GLSUN's Faraday isolator are devices that allow light to pass in one direction while blocking reflections in the opposite direction. They are used in free-space optical systems, where light travels through air or vacuum, rather than through optical fibers.
Features
• High isolation and low insertion loss
• Polarization dependent
• Compact size
• RoHS 6/6 compliant
Applications
• Optical transmitter
• Laser diode package
