Single Mode Fiber
A single-mode fiber is an optical fiber with a very small core diameter that can only transmit one mode of light. It features minimal intermodal dispersion, long transmission distance, large bandwidth, and high reliability. CNI adopts and optimizes pure silica core single-mode fibers to meet a wide range of application needs within the visible light wavelength range of 400 to 700 nm. Compared with germanium-doped fibers, this pure silica core fiber can be used in fields with more stringent requirements for low attenuation and high radiation resistance. These high-performance fibers are suitable for RGB fiber coupling, pigtailed laser diode output, and single transmission applications.
