Abstract (en)

[origin: CA3202236A1] The invention relates to a silica optical fiber (10) resistant to radiations (R) comprising: - a core (20);- a sheath (30) surrounding the core; - a polymer coating (40) encasing the sheath, said coating being able to form hydrogen (H2) by radiolysis under the effect of the radiations so as to diffuse it into said optical fiber.The invention relates also to an optical fiber device comprising at least one such radiation-resistant silica optical fiber.
