The F-SM-300-SC and F-SM400-SC are designed for Ultra-Violet (UV) and Visible wavelength transmission. The silica core prevents photo darkening effects, which are normally associated with Germanium doped fibers.
Fluorinated, depressed cladding design allows the core to be made from pure silica without the need for Germanium doping.

F-SM-300-SC和F-SM400-SC被设计用于紫外线和可见波长传输。二氧化硅芯防止了通常与掺锗纤维有关的光变暗效应。
氟化、凹陷的包层设计允许核心由纯硅制成,不需要掺杂锗。
