Abstract
Monitoring a well flow device by fiber optic sensing. A system includes processing circuitry configured to be disposed downhole in a wellbore. The processing circuitry is configured to receive a downhole parameter signal that represents an operational parameter of a well flow device in the wellbore, and perturb a fiber optic cable, based on the downhole parameter signal, to transmit the downhole parameter signal over the fiber optic cable. A fiber optic sensing system is coupled to the processing circuitry via the fiber optic cable. The fiber optic sensing system is configured to be disposed outside of the wellbore to extract, from the fiber optic cable, the downhole parameter signal.
