The document discusses connection losses in optical fiber communication, including extrinsic losses from Fresnel reflections, fiber misalignment, and other factors, as well as intrinsic losses related to differences in core diameter, numerical aperture, and refractive index profile between connected fibers. It provides equations to calculate insertion loss due to factors like fiber misalignment and presents examples of calculating loss when fibers are laterally offset with and without an index matching fluid.
