High-temperature resistant optical fiber

Abstract

The invention provides a high-temperature resistant optical fiber. The high-temperature resistant optical fiber comprises a glass core layer (1), a glass cladding layer (2), a paraffin layer (3), a metal coating layer (4), and a high temperature resistant outer protective layer (5), a stainless steel tube layer (6) and a mica insulation layer (7) which are distributed sequentially from inside to outside. The high temperature resistant outer protective layer (5) includes the following components in parts by weight: 200 to 230 parts of ionized water; 15 to 25 parts of sodium chloride; 5 to 7 parts of antifoaming agent; 8 to 14 parts of leveling agent; 3 to 5 parts of emulsifier; 5 to 10 parts of ethylene glycol; 260 to 300 parts of polymer resin emulsion; 1 to 2 parts of thickener; 1 to 4 parts of water repellent agent; 3 to 6 parts of PVC; 5 to 9 parts of bamboo powder; and 80 to 100 parts of silicon dioxide. The high temperature resistant optical fiber provided by the invention has good communication stability under extreme high temperature conditions.

Description

technical field [0001] The invention belongs to the field of photoelectric materials, in particular to a high temperature resistant optical fiber. Background technique [0002] With the continuous development of luminescent fiber technology, luminescent fiber optics have been widely used in fields other than the telecommunications industry, such as military, electric power, engineering monitoring (sensing), petrochemical and medical fields. Especially in some special fields, luminous optical fiber is more and more valued and favored due to its advantages of large information transmission capacity and strong anti-electromagnetic interference ability. [0003] Nowadays, with modernization and information technology, optical fiber has been needed by all walks of life. The general optical fiber is sheathed with PE plastic. Low. However, for some special industries such as petrochemical, steel, aerospace, boilers and other industries related to heat and high temperature, optica...
