Using the equation

\alpha=10 \log \left(\frac{P_{\text {input }}}{P_{\text {output }}}\right)

, calculate the attenuation of an optical fiber when the input power is

P_{\text {input }}=2 \ \mathrm{mW}

, the output power is

P_{\text {output }}=15 \ \mu \mathrm{W}

, and the fiber length is

d=25 \ \mathrm{km}
