The optical attenuation of the spliced fiber optic cable is too high
Modern fiber optic networks usually keep splice loss low, as shown below: You should know that each splice can add 0. If losses add up, you may face poor signal quality and need more maintenance. This helps the network stay. Fiber loss, also called fiber optic attenuation or attenuation loss, refers to the loss of signal between input and output. Thus manufacturers work very hard to control these parameters, including continuous testing throughout the manufacturing process. Thus, fiber splicing is what makes long-distance optical fiber communication possible.
