Question

#1. An LED launches 180$\mu$W of power into the end of a fiber. a. How much power would emerge at the end of the fiber at a distance of 500m if the fiber were specified as having a loss of 0.2dB/km. b. What would the loss of the fiber be in decibels per kilometer if 172$\mu$W were measured at the output of the fiber 500m away?

          #1. An LED launches 180$\mu$W of power into the end of a fiber.
a. How much power would emerge at the end of the fiber at a distance of 500m if the
fiber were specified as having a loss of 0.2dB/km.
b. What would the loss of the fiber be in decibels per kilometer if 172$\mu$W were
measured at the output of the fiber 500m away?
