Abstract
A method of making a polyimide coated heavy metal fluorinated fiber includes the steps of drawing an optical fiber through a low-temperature curing polyimide solution to form a polyimide coating which cures in a range of about 200.degree. and 390.degree. C. A low curing temperature enables a low temperature profile to be used for curing the coating. The low-temperature curing conditions provide a maximum fiber exposure temperature above the glass transition temperature of the fiber but minimize crystallization of the fiber during curing. The method is also applicable to chalcogenide fibers which carry optical signals in the infrared region.
