9um SM Fibercore 1250(9/80)single mode fiber

9um SM Fibercore 1250(9/80)single mode fiber

The 9μm SM Fibercore 1250 (9/80) is a high-quality reduced cladding single mode fiber designed for compact and space-constrained optical applications. Manufactured by Fibercore (part of Humanetics Group), this specialty fiber features a 9μm nominal core and an 80μm cladding diameter, offering an excellent balance of optical performance and mechanical reliability.

Optimized for operation in the 1310nm and 1550nm telecom windows, the SM1250 (9/80) delivers low attenuation, good mode field control, and enhanced bend performance compared to standard 125μm fibers. Its smaller cladding diameter significantly reduces package size and bending stress, making it ideal for miniaturized optical assemblies where standard fibers are too large.

Product Features & Benefits

• Reduced Cladding Design (80μm): Enables smaller coil diameters and more compact device packaging compared to conventional 125μm fibers.
• Excellent Bend Performance: Lower bending stress and improved macrobend loss in tight spaces.
• Optimized for 1310/1550nm: Reliable dual-window performance for telecom and sensing applications.
• High Mechanical Reliability: Reduced cladding lowers internal stress in coiled or bent configurations, extending service life.
• Tight Geometric Tolerances: Superior core/cladding concentricity for consistent fusion splicing and coupling.
• Dual Layer Acrylate Coating: Provides excellent protection and flexibility (170μm coating diameter).
• Proven Specialty Fiber Technology: Backed by Fibercore’s long-standing expertise in reduced-diameter fibers.
