780 nm Select Cutoff Single-Mode Fiber
Nufern’s 780-HP high-performance select cutoff single-mode fiber is optimized at near IR wavelengths. This application-specific fiber was developed for applications requiring coupler generation, diode pigtails and unique delivery needs for the near IR continuum. Compared to the best fibers available today, 780-HP fiber features higher proof test levels and tighter second mode cutoff tolerance. These features result in higher strength, increased component reliability, improved production yields and reduced costs for component manufacturers.
≤ 4.0 dB/km @ 780 nm
