Attenuation In Optical Fibers And Calculation
As the distance light travels through an optical fiber increases, the light''s strength decreases; this phenomenon is known as “fiber attenuation.” It is also known as fiber loss or signal loss.

Another technique is fusion splicing, where the fibers are fused together, e.g. using an electrical arc. This leads to particularly low insertion loss and high return loss, if the two fiber cores are similar. For

ITU-T Rec. L.400/L.12 (02/2022) Optical fibre splices
Splicing of multimode fibres with cladding alignment provides sufficient attenuation performance since multimode fibre has a relatively large core diameter compared with a single-mode fibre.

Multimode Splice Loss
Even when splicing identical fibers together, if they are not perfectly aligned, optical power will be lost and attenuation across the splice will exist.

Optical Fiber Loss and Attenuation | MEETOPTICS Academy
Attenuation refers to the amount of signal loss as it travels down the fiber, typically expressed in dB/km. Losses can be caused by scattering, absorption, dispersion & bending.
