How much optical attenuation occurs after passing through the junction box

By joining two optical fibers end to end splicing aims to ensure that the light passing through it is almost as strong as the original wire without any joins. Losses can be introduced by various means such as intrinsic material absorption, scattering, bending, connector loss and more. Attenuation is a term in communication that refers to loss (reduction) in signal strength when a signal is transmitted from sender to the receiver. For example, if you directly test the power of an optical module with an optical power meter, you will get the optical power of the optical module. This document describes how to calculate the maximum attenuation for an optical fiber.
