CMS-HP, Cladding Mode Suppressed Photosensitive Optical Fiber
Coherent CMS-HP fiber is a photosensitive single-mode fiber designed for creating complex Bragg grating structures with high channel count. It features excellent cladding mode suppression, high intrinsic photosensitivity, and low polarization mode dispersion (PMD), making it ideal for demanding telecom applications.
Features and Benefits
- Excellent cladding mode suppression - Allows for tighter channel spacing
- Mode matched to conventional transmission fibers - Low splice loss
- Designed to achieve low PMD - Enables low PDL device development
- RoHS compliant
Applications
- Dispersion compensators
- DWDM gain flattening filters
