US 2023/0408782 A1 · FIBER INSULATOR WITH FIBER OPTICAL CABLE

Abstract

A fiber insulator (100) with a fiber optical cable (200) is provided. The fiber insulator (100) comprises a fiber optical cable (200); a ceramic jacket (120), wherein the ceramic jacket (120) is hollow, wherein the ceramic jacket (120) has an inner whole diameter (D) configured to guide the fiber optical cable (200); an insulating filling material (130), which at least partially fills out the ceramic jacket (120) and is arranged between the fiber optical cable (200) and the ceramic jacket (120), wherein the insulating filling material (130) has thermal properties similar to the thermal properties of the fiber optical cable (200) and the ceramic jacket (120), and wherein at least one end of the fiber insulator (100) is closed by at least one end cap (151, 152).
