Splicing and Connection Performance Three factors that could affect splice performance can be caused by attenuation, modal dispersion, and chromatic dispersion. Attenuation can cause performance issues because of dirty fiber end faces, excessive gaps between fibers or improperly installed connector offsets of fiber cores when mated. Another factor that can affect performance connections is angle acceptance also known as modal dispersion. This has to do with a differential delay between the modes, which can cause for a lower bandwidth. Then there is chromatic dispersion which is the limited bandwidth of certain single mode optical fibers. This has to do with the length of light that is emitted through wave lengths. The best way to avoid these affects is to make sure the ratings match and the splicing is perfect, as well as the end faces meet.
Three factors of Intrinsic in connection performances is commonly affected by Numerical Aperture Mismatch, Core Diameter Mismatch or Mode field Diameter Mismatch. An NA mismatch can occur when the NA of one optical fiber is different from the NA of the other optical fiber. In Core diameter mismatch this can occur when there is a difference in the core diameters of the two optical fibers and Mode field diameter mismatch occurs when there is a difference in the mode field diameters of two single mode optical fibers. To avoid these issues you want to make sure that the mating sleeves are clean and free of dirt. Use of the proper cutting equipment for splicing for appropriate diameters of each end faces match.
Three factors of Extrinsic in connection performances aren’t normally have to do with the fiber itself. In most cases extrinsic
