980C-HP, Select Cutoff SM Optical Fiber
Coherent 980C-HP fiber is a high-performance, mid-NA fiber optimized for coupler manufacturing in the telecom industry. Designed for low, consistent splice and bend loss, it minimizes excess loss in couplers and supports long-term reliability in tight bend radius applications.
Features and Benefits
- Exceptional uniformity and core/clad concentricity - Low, consistent splice loss
- Extremely tight second mode cutoff tolerance - High yield coupler manufacturing
- Higher proof test levels - Critical for long-term reliability in tight bend applications
- RoHS compliant
Applications
- WDM pump/signal couplers for EDFAs
- CATV couplers and tap couplers
- Bi-directional splitters and combiners
- Ultra-compact components requiring small bend radii
