Standard loss value for multimode fiber optic fusion splicing
Similarly, the TIA standard for multimode optical fibers (OM2, OM3, OM4) specifies a maximum splice loss of 0. 3 dB for fusion splicing and 0. Typical splice loss values (the measure of loss in optical power across the splice point) are usually lower for fusion splices (typically less than 0. The loss spec for prepolished/mechanical splice connectors or multifiber connectors like MPOs will be higher (0. 75 max per EIA/TIA 568) When testing cable plants per OFSTP-14 (double ended). Generally, the standard splice loss for single-mode fiber is around 0.
