Should that fiber be rejected? Well, no, because the uncertainty of the loss budget is probably ~+/-0.5dB, providing a range of 7.5 to 8.5dB loss. The uncertainty of the loss test is probably in the same

This value represents the inherent signal loss per kilometer of fiber optic cable. It depends on the cable type (e.g., multi-mode, single-mode) and the wavelength of light used.

You can either compare this loss value to the application requirement or calculate the expected loss based on how many connectors and splices are in the link along with the length of the fiber link and

Fiber loss is another fundamental limiting factor as it reduces the average power reaching the receiver. Since optical receivers need a certain minimum amount of power for recovering the signal accurately,
