Fiber optic splice loss is negative

If the second fiber has higher backscatter than the first, the OTDR can measure apparent gain (negative loss) at the splice. It is impossible -- a passive splice cannot amplify light -- but it appears...

Calculating Fiber Optic Loss Budgets

As optical signal from the transmitter travels down the fiber, the fiber attenuation and losses in connections and splice reduces the power as shown in the green graph

Multimode Splice Loss

Fiber misalignment is a byproduct of the splicing process and can occur with any splice. Even when splicing identical fibers together, if they are not perfectly aligned, optical power will be lost and
