what is the maximum permissible insertion loss for splice fiber optic connections
When testing per FOTP-171 (single ended), include only one connector-the one atached to the launch cable. Splice Loss. For each splice, figure 0.3 dB (0.3 max per EIA/TIA 568). Fiber Loss. For multimode fiber, the loss is about 3 dB per km for 850 nm sources, 1 dB per km for 1300 nm.(3.5 and 1.5 dB/km max per EIA/TIA 568) This roughly translates into a loss of 0.1 dB per 100 feet (30 m) for 850 nm, 0.1 dB per 300 feet(100 m) for 1300 nm.hen testing per FOTP-171 (single ended), include only one connector-the one atached to the launch cable.
