Optical fiber structure
The bare fiber is generally divided into three layers:
First layer: high refractive index glass core (core diameter is generally 9-10μm,(single mode) 50 or 62.5 (multi-mode).
The second layer: low refractive index silicon glass cladding in the middle (diameter is generally 125μm).
The third layer: the outermost is a resin coating for strengthening.
1) Fiber core: high refractive index, used to transmit light;
2) Coating: refractive index is low, forming total reflection condition together with fiber core;
3) Protective jacket: strong, can withstand large impact, protect optical fiber.
