Abstract
A powered fiber optic cable for use in a hydrocarbon well of extensive depth and/or deviation. The cable may couple to a downhole tool for deployment to well locations of over 30,000 feet in depth while maintaining effective surface communication and powering of the tool. The cable may be configured to optimize volume within a core thereof by employing semi-circular forward and return power conducting portions about a central fiber optic portion. As such, the cable may maintain a lightweight character and a low profile of less than about 0.5 inches in diameter in spite of powering requirements for the downhole tool or the extensive length of the cable itself.
