Abstract
Messages on controller area network (CAN) buses are communicated over subsea links to subsea devices that also require electrical power to function. These subsea devices may be disposed kilometers away from the signal source where electrical signal and power transmission is impractical. The present invention provides a subsea power-over-fiber CAN bus converter for converting CAN bus electrical input and electrical power input into optical signals for transmission over a fiber optic cable for conversion into CAN bus electrical output and electrical power output for use by a subsea sensor or other subsea device. The subsea power-over-fiber CAN bus converter of the present invention is may comprise a flying lead harness that has a first connector end, a second connector end, a first optical converter module, a second optical converter module, and a fiber optic cable disposed between the first and second optical converter modules.
