Different single-mode optical fibers have high splicing loss
Insertion 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. 5 dB/km at either wavelength for outside plant max per EIA/TIA 568)This roughly translates into a loss of 0. 1 dB per 600 (200m) feet for 1310 nm, 0. 1 dB per 750 feet. Optical fibers can be joined together, such that light is efficiently transferred from one fiber to another.
