Smart Product Number: 1310M-HP
1310/1550 nm Bend Insensitive Medium-NA Select Cutoff Single-Mode Fiber
Nufern’s 1310/1550 nm high-performance select cutoff single-mode fibers are optimized for use by component manufacturers in the telecommunications wavelengths. These application-specific fibers were developed for small form factor components. Nufern’s fibers offer exceptional uniformity and core/clad concentricity, very tight second mode cutoff tolerances, and tight bend radius specifications for applications in miniaturized fiber optic packages. These high-performance specifications result in superior strength, increased component reliability, improved production yields and reduced component manufacturer costs.
