Conventional tight-packed fiber diameter 0.9mm
Causes of Fiber Attenuation
The main factors that cause fiber attenuation are: intrinsic, bending, extrusion, impurities, unevenness and butt joint, etc.
Intrinsic: It is the inherent loss of the fiber, including: Rayleigh scattering, intrinsic absorption, etc.
Bending: When the fiber is bent, part of the light in the fiber will be lost due to scattering, resulting in loss.
Squeeze: The loss caused by the slight bending of the fiber when it is squeezed.
Impurities: Impurities in the fiber absorb and scatter the light propagating in the fiber, resulting in loss.
Inhomogeneity: The loss caused by the inhomogeneity of the refractive index of the fiber material.
