摘要：
Dual coated optical fibers and methods for forming dual coated optical fibers are disclosed herein. The dual coated optical fibers include a glass fiber comprising a core region, a cladding region and a dual coating layer surrounding the glass fiber. The dual coating layer includes an inner coating and an outer coating. The inner coating surrounds the glass fiber and includes a first polyimide material. In one embodiment the first polyimide material also includes an adhesion promoter. The outer coating surrounds and is in direct contact with the inner coating and includes a second polyimide material having a decomposition threshold temperature greater than the first polyimide material. The second polyimide material may also have a modulus of elasticity greater than the first polyimide material and a moisture uptake lower than the first polyimide material.
