SM-9/105/125-20A, Passive Double Clad Optical Fiber
Coherent single-mode double clad coupler fiber is designed for 1550 nm amplifier modules utilizing higher power multimode pumps. This fiber is ideal for the signal leg in high-power CATV couplers, offering low splice loss and optimized acceptance of multimode pump energy.
Features and Benefits
- Single-mode core - Low splice loss to SMF
- Glass-on-glass double clad structure - Compatible with Nufern Power Delivery Fibers
- Exceptional geometric uniformity and core/clad concentricity - Superior fiber diameter tolerances
- RoHS compliant
Applications
- CATV pump/signal couplers
- Laser delivery/fluorescence
