SM 1500 bending insensitive single mode fiber

SM Fibercore 1500 Bend Insensitive Single Mode Fiber (SM1500 Series)

The SM Fibercore 1500 (SM1500 Series) is a premium bend-insensitive single mode fiber engineered for demanding applications in the 1520–1650 nm wavelength range (C + L band).  this specialty fiber family offers outstanding bend performance, high numerical aperture (NA), and optional reduced cladding diameters (80μm), making it ideal for compact, high-reliability, and harsh-environment optical systems.

Available in multiple core sizes and coatings (including high-temperature polyimide), the SM1500 series delivers exceptional performance in tight coils, miniature packages, and extreme temperature conditions while maintaining low attenuation and high mechanical reliability.

Product Features & Benefits

• Excellent Bend Insensitivity: Significantly lower macro-bend loss than standard single mode fibers, suitable for tight coil diameters.
• Reduced Cladding Options (80μm): Enables smaller package sizes and reduced bending stress for miniature coils.
• High Temperature Performance: Available with polyimide or high-temperature acrylate coatings for extreme environments.
• Photosensitive Variants: Ideal for Fiber Bragg Grating (FBG) inscription in sensor applications.
• Low Attenuation: Excellent signal transmission in the C + L band.
• High Mechanical Strength: High proof test levels for long-term reliability under stress.
• Tight Geometric Tolerances: Superior concentricity for low-loss fusion splicing and component manufacturing.
