Abstract
The present techniques are directed to systems and methods for monitoring parameter data from sensors, for example, in a subsea environment. In one method, an electrical signal including data from the subsea unit is converted into an acoustic signal. The acoustic signal is directed through the water column towards a fiber optic cable. The acoustic signal is detected by changes in a light signal carried in the fiber optic cable, and the changes in the light signal are decoded to obtain a data stream representing the parameter data.
