What is a Good dB Loss for Fiber Optics?
An acceptable dB loss is typically around 3.5 dB/km at 850 nm and 1.5 dB/km at 1300 nm for standard multimode fibers. The loss is much lower, with an acceptable dB loss of around 0.4

Guidelines On What Loss To Expect When Testing Fiber Optic Cables
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)
