"WebInsertion loss, defined as the loss in optical power at a joint between identical fibers, typically is 0.2 dB for mechanical multimode splices. Since single-mode fibers have small optical cores and hence small mode-field diameters (MFD), they are less tolerant of misalignment at a joint. " - Optical insertion loss
