Polarization-Insensitive Optical Isolator
In communication lines or EDFA, In-line optical isolators are generally used, because the polarization characteristics of light on the line are very unstable, which requires the device to have a small polarization-related loss.
This product adopts advanced manufacturing industry, has stable mechanical, physical and optical characteristics, and has the characteristics of high isolation, low insertion loss.
Product Features：
- High Isolation & Return Loss
- Low Insertion Loss
- Low Polarization Sensitivity
- Optical Path Epoxy Free
Product Application：
- Fiber optic Amplifiers
- CATV Fiber Optic Links
- Fiber optic Systems Testing
- Fiber Optic Lan Systems
- Telecommunications
