Our Pure Silica Core SM fibers (SM-SC) are designed for high performance in demanding applications. 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.

我们的纯硅芯SM纤维(SM- sc)是为高要求的应用而设计的。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。
