SM450 Short-Wavelength Single-Mode RGB Fiber

Single Mode Fiber (SMF) refers to an optical fiber that supports only one transmission mode at a specific wavelength (with two degenerate polarization modes allowed). Single mode fibers typically have a core diameter in the range of 10 microns, with a very small refractive index difference between the core and cladding (<1%). Due to the characteristics of single-mode fibers, such as long transmission distance, high bandwidth, low transmission loss, no intermodal dispersion, and strong reliability, they can be used in outdoor long-distance data transmission, fiber optic communications, fiber optic sensing, and other fields. SM450 fiber, when fused with a coupler, has a very low splice loss and is suitable for device connector manufacturing.
