Fiber Optic Cabling Loss Limits Explained – Trend Networks
For multimode fibre, a reading of less than 3.0 dB/km at 850nm is considered good. For single-mode fiber, a reading of less than 0.5 dB/km at 1310nm or 1550nm is ideal.

Multimode loss is inherently more uncertain than single mode loss, with additional variables as follows: Attenuation varies depending on the power distribution (beam geometry) across the fiber core.
Guidelines On What Loss To Expect When Testing
The uncertainty of the loss test is probably in the same range, so the actual loss is in the range of 7.7 to 8.7dB. Thus there is considerable overlap of the loss budget
