Features and Benefits
- Enhanced photosensitivity - Shorter grating writing time
- Mode-matched to transmission fibers - Low splice loss
- Tightly controlled specifications - Excellent uniformity
- RoHS compliant
Applications
- WDM
- Gain flattening filters
- Dispersion compensators
- Pump stabilizers
