attenuation coefficient
Fiber attenuation per unit length, usually expressed in dB · m –1 .
loss balance sheet (or liaison balance sheet); loss budget
Sum of the fiber optic section loss and penalties (in dB), at the start of the link's existence. The final balance is the sum of the initial balance and the reserve margin (in dB).
backscatter coefficient
For a given pulse, the ratio between the backscattered power at the fiber input and the input pulse power. This corresponds to the...
