The F-SM1500SC-9/125 and F-SM1500SC-9/125-P are designed for use in Hydrogen-rich environments where the pure silica core resists the effects of Hydrogen darkening. 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. The F-SM1500SC-9/125-P is designed specifically for down hole Oil & Gas applications. The fiber is engineered to resist the effects of Hydrogen ingress and when used with the high performance Polyimide coating, ensures the fiber is suitable for high temperature down hole applications.
